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. 

The County’s contractor, Cox Commercial, has scheduled a traffic change for Thursday night, March 1, on the RM 620 project.   Weather permitting, the two westbound lanes from Deep Wood to just west of Wyoming Springs will be shifted to the north onto the new pavement.  Restriping, adjustment of traffic signals and the lane shift work will take place between the hours of 8 p.m. and 5 a.m.  Shifting the traffic lanes will provide a work zone between the eastbound and westbound lanes necessary to complete the construction of an additional lane in each direction and the raised center median.  Access to side streets and driveways will be maintained at all times.  Police officers will be on hand to manage traffic at the signalized intersections if necessary.  No delay to traffic is expected during this work.
