PROJECT SUMMARY

The Texas Department of Transportation (TxDOT) is managing a project that converts the 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.  During peak travel times—southbound in the morning and northbound in the evening—high-occupancy vehicles (HOVs), low-emissions vehicles and motorcycles will be allowed to access the technology lanes. In non-peak hours, HOVs, low-emissions vehicles, motorcycles and single-occupant vehicles (SOVs) will be allowed in the peak-hour lanes.
