SULPHUR, LA (KPLC) - It could be a sign of just how hot it's going to get this summer. Sulphur officials were called out to Maplewood Drive just before five o'clock after hearing a loud boom. What they found was a large crack across all four lanes of Maplewood Drive. Westbound traffic was diverted to Louisiana Avenue while Sulphur Public Works worked to fix the problem. They say they won't know for sure what happened until they dig up the section of damaged roadway.
