Expect heavy traffic congestion and delays Friday on Interstate 12 westbound from Juban Road to O’Neal Lane, according to State Police and DOTD.

The roadway will be reduced to one lane until 3 p.m. to facilitate ongoing construction efforts.

Westbound traffic on I-12 has backed up from O’Neal Lane in East Baton Rouge Parish to Walker in Livingston Parish as a result of construction work and minor accidents, authorities said late Friday morning.

Traffic has been reduced to one lane on I-12 near the Amite River and there have also been a couple of minor accidents, Denham Springs police spokesman Shawn Perkins said.

Most of the backup is due to the lane closure for the construction work, Perkins said.
