The I-49 Lafayette Western Bypass Option: The "Lafayette Regional Xpressway"

One bypass alternative for Lafayette has been under study by the DOTD since 2003. At that time, the Lafayette Metropolitan Expressway Commission was created by the Louisiana State Legislature. They are commissioned to study alternatives for the Lafayette Regional Xpressway, or simply the LRX. The LRX would create a bypass loop which begins in the south at Highway 90 / I-49 south of Broussard, has a major interchanges as it crosses Highway 167 (Johnston Street) north of Abbeville, and I-10 between Duson and Scott. This portion of the roadway would be very roughly 25 miles. The bypass would then continue north and east for roughly 20 miles to return to I-49 north of Carencro. An eastern bypass leg of very roughly 15 miles would run south east from north of Carencro to I-10 west of Breaux Bridge. Total length of the Lafayette Regional Xpressway bypass would then be very roughly 60 miles.

At an estimated cost of $760 million, the cost per mile for this roadway is under $13 million per Interstate mile. The 5.5 mile Lafayette Connector project which now has cost estimates of over $1 billion before toxic waste removal and flood mitigation have even been considered. This gives the Connector a cost that will greatly exceed $182 million per mile.
