RM 620 Phase 2

Location From Cornerwood to Deepwood Drive
Description This RM 620 project is approximately 2.74 miles in length and is made up of two segments.

Segment 1 (Cornerwood Drive to Wyoming Springs Drive):
This segment of roadway is a TxDOT project to restripe the existing four lane section to a six lane section.  Sidewalks along the north side of RM 620 in this segment are also planned; however funding has not been identified at this time.  

Segment 2 (Wyoming Springs Drive to Deep Wood Drive):
This segment of roadway is a Williamson County project to widen the roadway from four to six lanes and will include new curb and gutter and a raised median.  This segment will also include left and right-hand turn lanes, culverts, water-quality facilities, retaining walls and construction of sidewalk along the north side of RM 620 to fill in the current gaps.

Status Segment 1: To be completed by TxDOT as funding becomes available.

Segment 2: The bid was awarded to Cox Commercial Construction on November 30, 2016. Construction started on January 13, 2017, and is anticipated to be completed in Spring 2018.
