Beginning Monday, February 10, 2014, US 90 will be reduced to one lane alternating in the eastbound and westbound directions for median shoulder work between La 3073 Ambassador Caffery near the City of Broussard and Wall Road in the City of Youngsville. This work will occur Monday through Saturday between the hours of 7:00 a.m. and 5:30 p.m. This portion of the project should be completed by Monday, February 24, 2014 - weather permitting.  All lanes will be opened at night and on Sundays. Permit loads are restricted to 16 feet in width. Emergency vehicles have access through the area.  No detour is necessary for this median work. Wall Road near the City of Youngsville in St. Martin Parish will continue to be closed between US 90 and Petroleum Parkway in order to reconstruct the intersection of Wall Road with US 90. This work will occur Monday through Saturday between the hours of 7:00 a.m. and 5:30 p.m. The Wall Road portion of the project was delayed by last week’s weather but is expected to be completed and the roadway reopened by Friday, March 14, 2014 - weather permitting.
