Williamson County officials are holding a public open house tonight for residents to receive information, ask questions and provide public comment on an arterial road work plan in west Round Rock. The proposed Corridor H/Sam Bass Road project would widen the roadway to three lanes with a center turn lane and add a shared-use path for bicycle and pedestrian access on the northern edge of the road. Officials estimate the project will cost $6.5 million. Improvements are planned on the entire 2.6-mile stretch of the road, spanning from RM 1431 to Wyoming Springs Drive. Improvements designed to alleviate bottleneck congestion on Sam Bass Road are planned at the intersections with RM 1431, Walsh Ranch Boulevard and Great Oaks Drive. Traffic signals will be added on Sam Bass Road at the intersections of Walsh Ranch Boulevard and Great Oaks Drive. Traffic data collected by the county shows the road registered 44 reported crashes from 2010-17 with more incidents occuring at intersections. According to county statistics, Sam Bass Road has about 8,900 average daily vehicles near RM 1431 and as much as 21,250 daily vehicles near Wyoming Springs Drive. As of yet, the Corridor H/Sam Bass Road project has no funding allocated and no timeline is set for the commencement of construction. The current plan was designed after hosting a public meeting in June 2017 and collecting comments online, according to county officials. The project received more than 300 comments from residents. County officials will be present tonight from 5-7:30 p.m. at Round Rock Presbyterian Church, located at 4010 Sam Bass Road, Round Rock, to present the current Corridor H/Sam Bass Road plan to the public and answer questions. Residents are encouraged to ask questions and provide feedback at the open house tonight or online.
