Southbound lanes of Interstate 35 through Troy were closed Thursday morning.

TxDOT officials are diverting traffic onto access roads after shutting down the highway near mile marker 306, adjacent to FM 1237/Pendleton Road between Troy and Temple. TxDOT says 6 to 12 inches of rain fell on the roadway as storm clouds rolled through the area Thursday morning, and more rain is expected.

There was also water covering the roadway near mile marker 308, officials said. Drivers should find an alternate route through that area or exercise extreme caution.
