Ranch-to-Market (RM) 620 South from SH 71 to Hudson Bend Road in northern Travis County experiences significant congestion. Along most of its length, RM 620 South functions as both a local thoroughfare and commuter highway. In most cases, it is the sole access to subdivisions, businesses, and schools. It is also a primary access route to Lake Travis area facilities. Travis County’s rapid growth has placed increased demand on this already congested highway. The Hill Country terrain, limited route alternatives, constrained right of way and environmental sensitivity limits solutions. The Capital Area Metropolitan Planning Organization 2040 Regional Transportation Plan identifies RM 620 as a six-lane divided major arterial.

Proposed Improvements:

The Texas Department of Transportation is proposing improvements to RM 620 South between SH 71 and Hudson Bend Road in Travis County. The proposed project plans to address safety and mobility concerns along this section of RM 620 with the following improvements:

  • Widening the existing four-lane divided rural roadway to a six-lane divided urban roadway, adding a third travel lane in each direction
  • Adding raised medians
  • Adding a continuous bike/pedestrian shared-use path along the corridor


Work began in May 2018 to develop design options for a build alternative, consider the no-build alternative and conduct an environmental study for the proposed improvements.

Get Involved:

The purpose of Open Houses and Public Hearings is to share project information and updates, present proposed project information, and collect community input. TxDOT is committed to working closely with the community on this project. All input will be considered as TxDOT moves forward in developing a plan to enhance the safety of this corridor while preparing for future growth.
