Interstate 310 at U. S. 90 Interchange

Burk-Kleinpeter, Inc. (BKI) designed a limited access interstate highway interchange and mainline section to connect the new Mississippi River Bridge at Luling, Louisiana, with the existing Louisiana Highway 3127 and US Highway 90 in Boutte, Louisiana. This interchange serves as the Southern-most terminus of I-310 and provides traffic coming from the growing communities in St. Charles Parish, Louisiana, with a direct connection to I-10 via I-310.

The 3.5 miles of rural interstate included bridges crossing small streams, two directional interchanges, and one steel curved girder bridge. BKI also designed the preliminary geometrics for the mainline continuation and the ramps connecting Highway 90 eastbound.

The construction cost for the completed portion of the project was $32 million.
