Highway 183

CTRMA

The Central Texas Regional Mobility Authority Board is moving forward with plans to add managed toll lanes to part of U.S. Highway 183 in Northwest Austin. The CTRMA board voted Wednesday to authorize final negotiations with the Texas Department of Transportation (TxDOT) to complete the $500 million project.

The project would add two tolled lanes in each direction for nine miles, from State Highway 45 to MoPac. Tolls on the new lanes would go up and down depending on demand, and would connect to the existing MoPac Express Lanes, which have the same variable tolling.

A stretch of US 183 in Cedar Park will be closed this morning.

Starting at 9 a.m., 183 will shut down between the Leander city limit and RM 620. The freeway will stay closed until sometime around noon.

The closure is needed to make room for two trucks carrying oversize loads. Power lines and stoplights need to be lifted along the route to allow the trucks to pass underneath.

Intersections and sections of the highway will be open before and after the trucks pass through each intersection, but traffic will be unable to pass the trucks in either direction.
