Highway / Express Lanes


The 35Express project includes nearly 30 miles of improvements to heavily congested I-35E between US 380 in Denton and I-635 in the northwest corner of Dallas. This corridor serves hundreds of thousands of commuters, handles substantial daily truck traffic, and is a primary link to major universities in the city of Denton, including the fourth-largest university in the state, the University of North Texas. The project will also add frontage roads across Lake Lewis, which will improve north-south commuting options.

In its ultimate configuration, the $4.8 billion project would rebuild the full corridor while adding tolled express lanes to provide a reliable alternative to the general purpose lanes and frontage roads. The project is proposed to be constructed in phases Phase 1's elements include:

  • Construction of two reversible managed toll lanes (express lanes) with associated exit/entrance ramps between Valley View Lane just north of I-635 and Turbeville Road/Hundley Drive 16.5 miles to the north
  • Addition of express lane connectors between I-35E and the existing LBJ Express along I-635
  • Reconfiguration and rehabilitation of general purpose lanes from IH635 to Corinth Parkway, 20 miles to the north
  • Reconfiguration and/or widening of general purpose lanes and the construction of an additional general purpose lane in each direction from Sam Rayburn Tollway (SH 121) to US 380 (21 miles)
  • Construction of direct connectors to Sam Rayburn Tollway (SH 121)
  • Construction of a collector-distributor system between President George Bush Turnpike and Sam Rayburn Tollway (SH 121)
  • Construction, reconstruction, widening, or rehabilitation of various frontage roads, interchanges, and bridges
  • Construction of a new southbound bridge over Lewisville Lake with four general purpose lanes, two reversible express lanes, two frontage road lanes, and a pedestrian walkway; reconfiguration of the existing north and southbound bridges to carry all northbound traffic on four general purpose lanes, two frontage road lanes, and a pedestrian walkway
  • Associated mitigation projects
