Flashing Yellow Arrows Soon to be Added to Traffic Lights in Southwest Louisiana

Modifications to Traffic Signals – Flashing Yellow Arrow – Calcasieu, Beauregard, Jefferson Davis, Allen, Cameron

The Louisiana Department of Transportation and Development advises motorists that beginning Monday, April 8 modifications will begin to most of the traffic signals on state routes in Calcasieu, Beauregard, Jefferson Davis, Allen, and Cameron Parishes. Modifications include installing flashing yellow arrows to left turn lanes and performing upgrades to traffic signals.

The flashing yellow arrow will replace a solid green bulb, indicating motorists should yield to oncoming traffic and pedestrians prior to performing a left turn. Flashing yellow arrow signals have been shown to increase safety and reduce traffic delays.

Work will begin in Calcasieu Parish along the following corridors: US 171, LA 14, LA 378 and I-210. The project is scheduled to be complete in late 2020.

DOTD appreciates your patience and reminds you to please drive with caution through work zones and be on the lookout for work crews and their equipment
