US 183 Frontage Road
Project overview
The US 183 frontage road project from RM 1431 to Avery Ranch Boulevard is designed to address congestion, enhance safety and improve mobility along US 183 in Williamson County. The approximate 3-mile project includes constructing two grade-separated lanes on each side of the Central Texas Regional Mobility Authority’s 183A toll road, as well as a shared-use path on the northbound side of the roadway, connecting to the existing US 183 trailhead.
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.
