Purpose TxDOT is proposing to improve US 75 from I-635 to SH 121/Sam Rayburn Tollway (SRT) in Dallas and Collin counties, Texas.

The proposed project would convert existing US 75 high-occupancy vehicle (HOV) lanes to peak-hour technology lanes from I-635 in Dallas County to SH 121/SRT in Collin County. No tolls will be charged to vehicles using the peak-hour technology lanes. Construction of the project will replace the double white stripes and pylons with broken white stripes to allow for continuous ingress and egress between the technology lanes and general-purpose lanes.

Dynamic message signs and overhead signs will be located at various locations to communicate operation times for the peak-hour technology lanes. During peak travel times – southbound in the morning and northbound in the evening – high-occupancy vehicles (HOVs), low-emission vehicles, and motorcycles will be allowed to access the technology lanes. In non-peak hours, HOVs, low-emission vehicles, motorcycles, and single-occupant vehicles (SOVs) will be allowed in the peak-hour lanes.

The proposed typical section would consist of:

  • Four 11-foot general-purpose lanes in each direction
  • One 11- to 12-foot peak-hour technology lane in each direction
  • 10- to 11-foot outside shoulders
  • A variable inside shoulder with concrete median barrier

No additional right of way would be needed for the project.


The virtual public hearing and in-person option will be conducted in English. If you need an interpreter or document translator because English is not your primary language or you have difficulty communicating effectively in English, one will be provided to you. If you have a disability and need assistance, special arrangements can be made to accommodate most needs. If you need interpretation or translation services or you are a person with a disability who requires an accommodation to attend and participate in the virtual public hearing or in-person option, please contact the TxDOT Public Information Office at (214) 320-4480 no later than 4 p.m. Monday, March 13, 2023. Please be aware that advance notice is required as some services and accommodations may require time for TxDOT to arrange.
