US 183 Frontage Roads
Project overview
TxDOT is constructing two grade-separated lanes on each side of the Central Texas Regional Mobility Authority’s 183A toll road from RM 1431 to Avery Ranch Boulevard in Williamson County. The project will also construct a shared-use path on the northbound side of the roadway, connecting to the existing US 183 trailhead.
Construction on the approximate 3-mile US 183 frontage road project is in progress, with completion anticipated in 2029.
Project purpose and benefits
Population growth and development in central Texas continues to increase. The US 183 frontage road project will improve mobility and safety by constructing frontage roads parallel to the 183A Toll. The frontage roads will also serve as a relief route when the toll road is closed for maintenance or incidents.
Other benefits include:
- Mobility. Improving travel times and mobility by alleviating the frontage road gap between RM 1431 and Avery Ranch Boulevard.
- Safety. Improving safety by constructing a tranditional frontage road concept to meet TxDOT current standards and reduce number of conflict points compared to the existing alignment.
- Environmental. Reducing emissions with fewer idling vehicles queued at the existing seven signalized intersections.
- Future Planning. Allowing the city of Cedar Park more flexibility to align future development and improvements with city transportation and master plans.
What to expect during construction
The community should plan for construction impacts to last around four years. Businesses, residents and drivers can expect to see and hear a variety of construction activities as work progresses.
