The Louisiana Department of Transportation and Development (DOTD) has announced a temporary road closure affecting LA 478 at the Union Pacific railroad crossing near its intersection with LA 1.

The closure is scheduled for Wednesday, July 15, 2026, weather permitting, and is expected to remain in place from approximately 8:00 a.m. to 7:00 p.m. for one day.

According to DOTD, the closure is necessary to allow Union Pacific crews to conduct maintenance work on the railroad crossing.

During the closure, traffic will be detoured from the LA 478 crossing west onto Interstate 49 northbound, then east onto LA 6 Business/University Parkway, and south onto LA 1.

Northbound traffic on LA 1 will continue north and use LA 6 (University Parkway) and I-49 southbound to reconnect with LA 478 eastbound.

Officials noted that all construction activity is weather dependent and may be rescheduled in the event of inclement weather. DOTD also reminded motorists to use caution when traveling through work zones and to be on the lookout for crews and equipment.
