Please comment on plans for the LRX: Interstate bypass alternatives
Several past posts on this blog, ConnectorComments.org, have dealt with Lafayette bypass alternatives that would compete with the proposed I-49 Connector which proposes to build an elevated urban interstate through the heart of Lafayette. Lafayette bypasses would compete with the I-49 Con for projected traffic load, and therefore funding and priority.
Last week, June 6th and 7th, the Lafayette Metropolitan Expressway Commission (LMEC) hosted open house meetings which updated information on their plans to build the Lafayette Regional Xpressway (LRX) as a partially toll-funded interstate bypass west of Lafayette.
The LRX bypass will allow through traffic to avoid passing through Lafayette's urban core, and should relieve the city of much of its heavy truck and hazardous cargo traffic. It would also draw traffic away from some of the heaviest traffic areas of the Parish.
The infrastructure solutions firm, HNTB, gave one-on-one presentations to the public during the LMEC open house. We were told that meeting materials would be posted on the LMEC web site after the meetings. That information is not yet posted, but I have scanned the meeting handouts which are available through these links:
- Handout (two pages)
- Map of alternative routes for comment (one page)
- Public questionnaire and comment form (2 pages)
Public comment on LRX planning has now been requested as a part of the project's Tier 1 Environmental Impact Statement (EIS). Completion of this EIS is anticipated at the end of this year. I urge all readers of this blog to comment, share, and ask friends to submit comments. Although our state and local politicians have financial and legal constraints that limit describing the LRX as an alternative to the I-49 Con, the obvious fact is that both would be competing parallel roadways, and funding completion of either makes it unlikely the other will ever be built! These projects are in a competition for priority and funds. Now it is up to the public to declare their preference.
The third document, the questionnaire and comment form, should be submitted to the email or postal address given at the bottom of the form. There is no set deadline for submitting public comment, but I believe it would be best to send in your comments within the next 2 weeks, and certainly by the end of June. Emailed comments should be sent to kbprejean@hntb.com

Secretary Pete: Put an immediate stop to the I-49 Lafayette Connector
Lafayette resident Ann Burruss sent the following letter to Secretary of Transportation Pete Buttigieg with copies to our Louisiana Governor, Lafayette Mayor, and Louisiana Transportation Secretary. The photos in this letter were taken by Ann earlier this month at the DOTD I-49 Open House poster presentation.
If you feel strongly about the Lafayette I-49 Connector, you too can voice your opinion to the U.S. Secretary of Transportation by sending a letter to: The Honorable Pete Buttigieg, U.S. Department of Transportation, 1200 New Jersey Ave., SE, Washington, DC 20590. You may also email the secretary at DOTExecSec@dot.gov.

Federal Aid Project No.: H004273
Secretary Buttigieg, November 17, 2021
Congratulations to you and to the Biden administration for passing the infrastructure bill. In my volunteer work for Second Harvest Food Bank in Louisiana, I drive on substandard roads in rural parishes and I know what this bill can mean for struggling workers who commute on bad roads and bridges. Thank you for putting the needs of working people first.
I am writing today to ask that you put an immediate stop to the federal highway project called the I-49 Lafayette Connector in Louisiana. While promoting the infrastructure bill the administration talks about racial justice and equity as driving factors in projects. Extending I-49 through the center of the city of Lafayette, Louisiana, is the exact opposite of that goal. The planned route replaces a surface road with an elevated interstate. It’s like the 1960s and 70s all over again! As if we have learned nothing about the damage -- the permanent dismemberment -- that an interstate highway does to a city. The I-49 Connector is racially unjust. It cements a redline through our city. It divides historically black communities from the prosperous downtown. We know better than we did in the 60s and 70s. We must do better.
The Louisiana Department of Transportation and their consultants held a series of sparsely attended open houses here recently. They never ask the public ‘Do you want this interstate? Do you need this interstate? If you need an interstate, where do you want it routed?’ It's always, ‘Do you like this lighting feature or that lighting feature? Do you want your children to be able to bike under this fabulous interstate, or do you want them to play basketball?’ I say “Neither.”
I and many informed citizens want this interstate to Not Be Built Here. Instead, we want to see the LRX (Lafayette Regional Xpressway) built. The LRX will provide the first half of a loop highway around our city. If this western loop portion proves useful and well-traveled, then an eastern portion could be built as an interstate through St. Martin Parish where they are willing and even eager to have a highway there. The LDOT will say that an eastern highway ‘on the Teche Ridge’ can’t be built because of wetland impact - and they are correct that wetlands mustn't be harmed because of their flood storage capacity and natural value. However, the Teche Ridge isn’t the only possible eastern route. Wetlands can be avoided. Please investigate and authorize these routes in lieu of the I-49 connector.
US Census data shows that from 2010 to 2020, the population of the parishes that the I-49 Connector is supposed to serve has dropped by 15%. The cost-benefit study for the I-49 Connector is very suspicious. How could it possibly have shown a positive cost for a highway to a rapidly depopulating area, an area that is losing its economic engine which is oil and gas production from which we must rapidly decarbonize? Accelerating coastal land loss will cause roads and highways south of Lafayette to face the open waters of the Gulf of Mexico. Additionally, the elevated route of this highway goes through a contaminated railyard and over our drinking water aquifer.
There is no reason to continue work on running I-49 through our city. Please quickly authorize more affordable and supportable projects to the east or west of the beautiful city of Lafayette, Louisiana, my home. Thank you.
Sincerely,
110 Seville Blvd

The I-49 Boondoggles
projects involving large numbers of people and usually heavy expenditure, where at some point, the key operators, having realized that the project will never work, are still reluctant to bring this to the attention of their superiors.Public opposition to routing I-49 through the heart of our city goes back at least to 1992, and for years now, Lafayette residents have recognized that the government project now being called the Lafayette I-49 Connector (we call it the I-49 Con) is a prime example of a wasteful government boondoggle (for an example of public comment read "Why the I-49 connector won't work" published May 27, 2016 in the Daily Advertiser). The public has been assured many times that if there is significant public opposition to the project it will never be built. Yet, the I-49 Con continues spending tens of millions of tax dollars on studies and design that will never be used for a footprint through the heart of the Lafayette.

The national Public Interest Research Group (USPIRG) published their 2018 list of US interstate highway boondoggle projects. If built as proposed, these boondoggles would waste tens of billions of our federal transportation tax dollars. And, even if these boondoggles are never built, billions will be spent on their planning and design before public pressure and simple rationality end their useless authorizations.
Although our own local boondoggle, the I-49 Con, did not make the USPIRG list this year, its sister project in Shreveport, the Shreveport I-49 Inner City Connection did make 2018's national list of worst boondoggles. Better luck next year to our own I-49 Con! If USPIRG accepts nominations in 2019 the I-49 Con will have my vote.
It is important that our political representatives hear from their voters about stopping these federal transportation boondoggles. If we don't speak up the only voices our leaders hear come from paid lobbyists representing the corporations and contractors who are hoping to continue getting design and construction contracts.
We do know that at least some of our leaders are hearing us. On October 17, 2018, One Acadiana hosted a 3rd Congressional District Candidate Forum. All seven remaining congressional candidates running in the November 6 general election participated in the forum:
- Rob Anderson,
- Aaron Andrus,
- Josh Guillory,
- Mimi Methvin,
- Larry Rader,
- Vernone Thomas, and
- Clay Higgins (incumbent).
Several of the candidates spoke to the forum in general terms about our need for improved infrastructure and the need to eliminate wasteful federal spending. However, two candidates spoke directly about problems with routing I-49 through the center of Lafayette. Congressman Clay Higgins noted that routing the interstate footprint through the central city would displace or impact a large number of private property owners. He concluded that an actual footprint for the project still needs to be selected. Candidate Mimi Methvin cited further problems with the central city route including its planned passage through the highly contaminated former railyard site. Furthermore, she noted that today urban experts and planners recognize urban blight in many US cities has been caused by the past construction of inner-city interstates.
Do you agree that the Lafayette I-49 Con is one more federal boondoggle currently wasting many tens of millions of tax dollars on design of a route through the heart of our city? Do you agree that, as now planned, the I-49 Con should never and likely will never be built?
If your answer is yes, I urge you to contact your chosen 3rd district candidate. Tell him/her of your opposition to the currently proposed central I-49 route. Ask your candidate to support planning for one of the much less costly and less damaging alternatives bypassing Lafayette to the east along the Teche Ridge or west following the plan for the Lafayette Regional eXpressway (LRX). In addition to saving federal and state taxes, either alternative also involves much lower cost to our local governments, reduces risks to property and health, and eliminates most impacts to flooding and traffic congestion inherent in the I-49 Con planned route through the heart our city.

Airport angles and increased risk
A LOT has been written on the topic of "things you just should never do." One of these "never do" actions is to build tall structures next to your airport. This is precisely the DOTD plan for extending I-49 through Lafayette.
In an earlier post I talked in general about the problems associated with the Connector plans relative to the Lafayette Airport. In this post. I want to get down to specifics.

| Figure 1. Google Earth image of the northwest end of runway 11-29 in relation to the intersection of Evangeline Thruway, University Ave, and Surrey St. |
Federal safety guidance defines the maximum height that objects should not exceed in the vicinity of airports. This definition is based on a number of imaginary surfaces through which no objects sitting on the ground should penetrate. Keeping aircraft above the imaginary surfaces, and all terrestrial objects below, provides for safe landings and takeoffs.
The lowest of these imaginary surfaces, the primary surface, is a rectangle at the elevation of the runway. The primary surface extends 200 feet beyond each end of the runway and 500 feet on each side of the runway centerline. Beyond each end of the primary surface there is an approach surface. The approach surface begins at the primary surface elevation and rises, for runway 11-29, at a slope of 34:1 (termed a 3% slope). That is, for every 34 feet of center-line distance the surface rises 1 foot. At their intersection, the width of the approach surface is the same as the primary surface, 1000 feet, and is centered on the runway center-line. The approach surface widens to 4000 feet at 10,000 feet ground distance from the primary surface. That is, the approach surface width is 1000+0.3x, where x is the ground distance along the center-line away from the primary surface. There are other defined surfaces (transitional surface, horizontal surface, conical surface), but only the primary and approach surfaces are relevant to the issue of runway displacement for 11-29.
The 2002 Final EIS asserts in numerous locations that the Lafayette Regional Airport runway 11-29 will need to be displaced 350 feet to the southeast toward Bayou Tortue and Cypress Island Swamp from its present location to meet minimum federal safety requirements for an approach surface slope of 34:1 and a 17 foot margin of safety (FEIS exhibit 4-4). While the FEIS makes the assertion that the 350 foot displacement is required, it does not show the underlying data or rationale needed to support the claim. I have therefore been forced to attempt to recreate these calculations. My calculations, however, do not agree with the conclusion in the FEIS. Lacking documentation of the FEIS methods, I conclude that the 350 foot assertion is likely in error.
A history and general information about the Lafayette Regional airport may be found in the Wikipedia article titled "Lafayette Regional Airport." Additional information on the airport AirNav.com. That web page also includes a link to a useful Airport Diagram. The diagram shows that runway 11-29 is 5401 feet long and 148 feet wide. Elevation at the northeastern end (designated 11) is 37 feet; elevation at the southeastern end (designated 29) is 35 feet.
Figure 1 is an image captured from Google Earth of the northwest end (designation 11) of runway 11-29. It illustrates that the runway does end quite close to the current highway. Measurement shows that the runway currently ends roughly 600 feet from Evangeline Thruway (Hwy 90), and roughly 700 feet from the intersection of the Evangeline Thruway, Surrey St, and University Ave.
Finally, it is necessary to estimate the height of objects above the roadway. This could include signs, streetlights, and aircraft warning lights. The FEIS does mention this, and suggests that special signage and lighting may be necessary. Thus, I will assume that the height of the vehicles on the roadway will be the tallest objects above the roadway. There is no Federal vehicle height requirement for commercial motor vehicles (CMVs). Most eastern states, including Louisiana, set a CMV height limit of 13.5 feet on most highways. Louisiana does allow heights of 14 feet on designated highways, and oversize permits can be routinely issued for heights up to 16 feet 5 inches. Without specific guidance from the Louisiana DOTD, it is unclear what height should be assumed. Here, I will simply assume a maximum height of 15 feet for all vehicles and objects on the roadway.
Assuming the peak height at the interchange structure controls the required runway displacement, the calculation of length for the approach surface is now straightforward. The interchange height plus object height has an elevation of 60 feet (45+15). Adding the FAA 17 foot margin of safety gives a total elevation of 77 feet. Subtracting the runway height which defines the primary surface elevation then gives a height of 40 feet (77-37). At a slope of 34:1, the length of the approach surface to the primary surface is 1,360 feet (34x40). At this point along the approach surface, the approach surface width is 1408 feet (1000 + 0.3x1,360), or 704 feet on each side of the extended runway center-line (Figure 3). Adding the 200 foot width of the primary surface at the end of the runway gives a total distance form the peak of the interchange of 1,560 feet. The present distance is estimated to be 700 feet, so the total runway displacement required would be 860 feet (Figure 4). This is 510 feet longer than the value asserted in the FEIS. This difference significantly brings into question the economic, environmental, and engineering feasibility of the displacement.
The calculated extension will require very roughly the destruction of 45 acres of the Cypress Island Swamp west of the airport (Figure 4), and more if embankments in the swamp must be longer than existing embankments. This considerably exceeds the 5 acres estimated in the FEIS (p 4-92).

The new extension into the swamp will need to deal with a very significant drop in elevation (Figure 5). As much as 35 feet of fill will be required for the extension. If earthen embankments are used at the sides of the filled area, considerably more than the estimated 35 acre area of wetland may be required in order to accommodate the more extensive embankment areas.

Options: What are our options? They include:
- The No Build alternative should always be considered. If the currently planned I-49 Connector project is abandoned, it could be replaced by upgrades to the current Evangeline Thruway, and bypass to the east along the Teche-Ridge, west using the LRX alignment, or both to form an urban loop.
- Build the connector project as decided in the FEIS and ROD, and extend runway 11-29 as required to meet minimum FAA guidelines. This will require land acquisition and a Corps of Engineers wetland permit. Likely this alternative will further require wetland mitigation and flood mitigation.
- Build the connector project as decided in the FEIS and ROD, and request an FAA exemption from airport approach obstacle safety requirements.
- Abandon use of runway 11-29.
- Revise the design in of the selected alternative to eliminate roadway elevation in the vicinity of the 11-29 runway approach surface.
SUMMARY: The I-49 Connector FEIS identified unacceptable risk due to failure to meet FAA flight path obstruction guidance, resulting from the proposed interchange construction adjacent to the Lafayette Regional Airport. Without documenting calculations or rationale, the FEIS stated that in order to meet these minimum safety requirements, airport runway 11-29 would need to be displaced 350 feet southeast toward Bayou Tortue and the Cypress Island Swamp.
My calculations, based on FAA guidance, arrive at runway displacement considerably longer than that presented in the FEIS. Here, following FAA guidance, I calculated that the required displacement is 860 feet. This significant difference brings into question the economic, environmental, and engineering feasibility of the displacement. Impact of this displacement on flooding, wildlife, and wetlands should be carefully addressed and documented by DOTD.
The public attitude toward airport safety should always be conservative and circumspect. The Airport's 1975 Master Plan concludes "Conditions at the airport's periphery make expansion of its land area difficult or expensive or both." Even beyond the impacts of runway displacement discussed above, it is simply inappropriate to choose to construct any tall structures on the periphery of our airport which is already severely constrained at its location. Tall structures like the University and Kaliste Saloom interchanges constrain future airport runway alignment adjustments, and impact the ability to meet current requirements and future safety requirements should FAA guidance on safety margins or approach slopes change for any reason.
