The Department of Public Safety is planning an investigation that will shut down a portion of I-35 in Troy Tuesday morning.

Southbound mainlines will be closed from mile marker 309 (FM 935 North of Troy) and mile marker 306 (FM 1237/Pendleton Road) for the investigation from 5am to 8am.

According to TxDot if the investigation concludes before 8am the mainlines will be re-opened. During the closure all traffic will be re-routed to the access road. Allow extra time if you have plans to travel through this area.
