Baton Rouge, LA (April 21, 2026) – A crash caused major traffic delays on Tuesday, April 21, along Interstate 12 East at Veterans Avenue in Baton Rouge.
Emergency units responded after a collision blocked the right lane on Interstate 12 East and also closed the entrance ramp from Veterans Avenue to the interstate. The incident led to significant congestion, with backups stretching approximately six miles.
Details regarding the number of vehicles involved and any possible injuries have not been confirmed. Authorities continue to monitor the situation and work to clear the roadway. More information is expected as the investigation continues.
Our thoughts are with those affected.
How Lane and Ramp Closures Impact Highway Traffic
When both a travel lane and an entrance ramp are blocked, congestion can build quickly on major highways. Drivers entering from ramps must merge into already slowed traffic, which can further back up traffic.
These conditions often lead to extended delays, especially during peak travel times. Limited merging space and reduced lane availability force vehicles to suddenly adjust their speed, which can ripple through surrounding traffic. Maintaining a safe following distance and allowing space for merging vehicles can help improve flow in these situations.
