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, and a variable inside shoulder with concrete median barrier. No additional right of way would be needed for the project.
