BATON ROUGE - The Acadian Thruway exit off of westbound I-10 was blocked Wednesday afternoon for a chemical cleanup. 

The Baton Rouge Fire Department said an 18-wheeler hauling diesel had a leak in its saddle tank. The driver stopped at the exit around 1:20 p.m. Approximately 50 gallons of fuel had spilled on the roadway. 

No injuries were reported.

Congestion was backed up past the 10/12 merge.
