Motorists traveling on Robson Ranch Road in southwest Denton should expect traffic delays beginning Monday, Aug. 10, as construction gets underway on an expansion project designed to improve traffic flow and safety. The project includes widening Robson Ranch Road from four to five lanes between Sagehawk Drive and I-35W, adding left-turn lanes and dedicated right-turn lanes. Improvements also include a fifth lane and a new left-turn lane at the Ed Robson Boulevard entrance to Robson Ranch, along with widening northbound Cleveland-Gibbs Road to add a dedicated left-turn lane and improve through and right-turn lanes. Eastbound motorists heading toward Hwy 377 are encouraged to use Cleveland-Gibbs Road or Harvest Way south to Old Justin Road or FM 407 before continuing east. The City of Denton is managing the project, with Denton County funding the design.
