What is the I-35E/US67 Project?

The I-35E/US 67 Project is a Texas Department of Transportation (TxDOT) Dallas District project that is developing long-term transportation and operational improvements to the southern gateway corridor. The purpose of the proposed project is to improve safety, congestion relief, traffic operations, address roadway deficiencies, and improve system linkage. The project proposes approximately 11 miles of improvements along I-35E from US 67 to I-30 and US 67 from I-20 to I-35E located within the City of Dallas and Dallas County, Texas.

The improvements would generally consist of adding reversible non-tolled express lanes and/or general purpose lanes to improve capacity in the corridor. Non-tolled express lanes are non-tolled lanes that are open to all users including SOVs (single occupancy vehicles) and HOVs (high occupancy vehicles) that would serve as a general purpose lane with limited access. And as an express lane, the operations could change over time to allow HOVs only during peak hour or trucks only at night. In addition, bicycle and pedestrian accommodations are proposed where frontage road reconstruction is proposed.

Proposed Improvements

Reference the map above to see where each proposed improvement will take place.

  • Tolled managed lanes have changed to non-tolled express lanes
  • Realigned the mainlanes to reduce the ROW footprint and displacements
  • Full reconstruction to include:
      • Two reversible non-tolled express lanes
      • Widening of the mainlanes from 8 to 10
      • Ramping modifications
      • Additional mainlane along I-35E from Marsalis Avenue to US 67 is proposed in each direction
      • Wider cross street accommodations for pedestrian and bicycle accessibility are proposed
      • Evaluated the feasibility of a potential deck plaza
      • Revised ramping to facilitate increased operations and local access
      • Maintained 10th Street as a through-street connection for vehicles and pedestrians
  • Tolled managed lanes have changed to non-tolled express lanes
  • Partial reconstruction to include:
      • Change the existing concurrent HOV lane to one reversible non-tolled express lane within the existing median
      • Increasing the number of mainlanes from 4 to 6
      • Ramping modifications
  • Shifted the managed lane access point north to allow access to/from Camp Wisdom Road
  • Providing ramping for increased Southwest Center Mall access along US 67
  • Reconstructing and relocating additional ramps to facilitate increased operations and local access

To be Constructed under a separate project and will not be procured under the I-35E/US 67 Project. However, the separate project will have similar anticipated begin and end construction dates

      • Tolled managed lane has been omitted
      • Increasing the number of mainlanes from 4 to 6
      • Reconstructing and relocating additional ramps to facilitate increased operations and local access
      • Local operational improvements such as turn lanes, u-turn bridges, and sidewalks have been evaluated to facilitate increased operations and local access
      • This portion of the corridor will be designed and constructed as a separate project, and not as a part of the I-35E/US 67 Project

Due to additional project development evaluation, there will be no proposed improvements until future funding can be identified.
