I-35 at Wells Branch Parkway


The project will include improvements to the intersections at FM 1825 and Wells Branch Parkway. The project will also include intersection bypass lanes to the I-35 frontage road to allow through traffic to bypass the traffic signal. In addition, entrance and exit ramps will be reconstructed on I-35 north and south of Wells Branch Parkway. Bicycle and pedestrian accommodations will also be improved along the I-35 frontage road.
