Starting at 9 a.m. June 7, US 75’s northbound high-occupancy vehicle lane through Plano and Allen will be closed as part of a $58.8 million project to convert it into a peak-hour technology lane.

What’s happening?

The lane will be closed long-term through fall 2025, according to a traffic alert from the Texas Department of Transportation. Motorists should be alert to crews working in the corridor and expect possible delays.

The closure will create space for crews to remove the highway’s old barrier and install a larger one, Public Information Officer Madison Schein said in an email. Construction crews will also install additional signage and conduits within the median as part of the larger project, she said.

No long-term closure of the southbound HOV lane is planned; however, periodic closures may happen at night, Schein said. Drivers on US 75 can keep up with future closures by checking

The background

The project, which was awarded to contracting company Webber, aims to convert HOV lanes along US 75 into peak-hour technology lanes. Construction crews will remove the pylons separating northbound and southbound HOV lanes, which will allow them to operate as general-purpose lanes during select hours.

Construction crews will also install additional lighting and signage as part of the project.

The project broke ground in March and is expected to be completed in late 2026, according to the traffic alert.

When completed, the new technology lanes will be limited to high-occupancy vehicles, low-emission vehicles and motorcycles during peak rush hours:
  • 7-9 a.m. southbound
  • 4-6 p.m. northbound
Each lane will be open to all traffic for the other 22 hours.
