PSC designed a highway expansion project for State Highway 155 in Anderson County, between Tyler and Palestine.

Under the direction of the Texas Department of Transportation’s Tyler District, PSC developed the plans and specifications to widen 10 miles of an existing, two-lane rural highway to a four-lane, divided rural highway. The design included the replacement of an existing 320-foot bridge over Caddo Creek and the addition of a new 400-foot bridge over Brushy Creek.

PSC also provided on-call services during the construction phase.
