 ST. MARY PARISH, La. - DOTD announces that beginning Sunday, January 5, 2025, until Monday, June 30, 2025, a traffic swap will occur along US 90 Westbound from just east of its interchange with LA 83 (Baldwin) to just west of its interchange with LA 318 in St. Mary Parish. During this time, traffic will be reduced to one lane and diverted to the inside lane of U.S. 90 eastbound.
 
 Additionally, the westbound lanes of US 90 in that area will be closed while the traffic swap is in place.
 
 This traffic swap is necessary for crews to perform paving operations and bridge repairs on the westbound lanes of US 90 in that area.
 
 The temporary lane configuration on US 90 Eastbound includes an 11-foot lane in each direction, with eastbound and westbound traffic separated by concrete barriers.  There will also be a 14-foot wide maximum restriction on oversized loads in that area.
 
 Emergency vehicles will have access to the area, but may encounter delays.
 
 DOTD appreciates your patience and reminds you to please drive with caution through the construction site and be on the lookout for work crews and their equipment.
