Stephenville public safety officials want motorists to be aware of traffic issues starting today around Hook Elementary School. Altered travel routes begin this morning, and certain streets will be closed or have parking restrictions in place for about three weeks. Road and sewer crews are working on the TSU Methodist Branch Sewer Relief Project. Stephenville ISD sent notifications home for parents and caregivers of the district’s third and fourth grade students. Public Works Director Nick Williams said a plan is in place to facilitate school buses and others picking up and dropping off students. A portion of Ollie Street will be closed to facilitate the infrastructure improvements.
