Project will add six lanes to heavily congested 9-mile route

AUSTIN (KJCE) -- One of Austin's busiest highway corridors is about to get an upgrade.

Last week, the Texas Transportation Commission approved $104.2 million in federal funding for a portion of the Central Texas Regional Mobility Authority's 183 North Mobility Project. The entire $504 million project covers a 9-mile stretch of U.S. 183 between State Highway 45 and MoPac, and will add two express tolled lanes and one general-purpose lane in each direction. The project will also add a direct connector between the MoPac express lanes and the new U.S. 183 express lanes.

A survey by the Texas Transportation Institute says the roadway is the 74th most congested in the state, and the mobility authority's projections show it getting worse each year.

"The 183 North Mobility Project will translate to a reliable nine-minute commute – a significant reduction in travel time for commuters using that corridor," said Mike Heiligenstein, executive director for CTRMA. "And commuters who prefer not to pay a toll will also benefit from the non-tolled components of this project. Building the non-tolled and tolled elements as part of the one project will minimize impacts to the driving public while maximizing cost and construction efficiencies."

The project will also include a multimillion-dollar investment in bicycle and pedestrian facilities, including two new shared-use path segments near Pond Springs Drive and new sidewalks and cross-street connections for bicycles/pedestrians.

The project is anticipated to break ground in early 2021, and construction along 183 North is expected to last approximately four years.
