Construction is officially in full swing on County Road 112 in Northeast Round Rock as the city aims to keep pace with the area's rapid growth. The project, which kicked off earlier this year, aims to transform the current two-lane road into a six-lane divided highway complete with a central median to better manage future traffic demands. Aside from the much-needed expansion, this initiative will introduce pedestrian facilities as well as upgraded storm drainage systems, reports Round Rock's official website.

The overhaul of County Road 112 encompasses two major projects: the East segment, which extends from County Road 117 to County Road 110, and the West segment, from A.W. Grimes Boulevard to County Road 117. The city's strategic planning efforts have found this expansion to be critical in order to adequately support the burgeoning residential and commercial developments. Dan Williams Company has been awarded the construction contract, and they are expected to quickly start to assemble the necessary utilities, aiming for a completion date in the fall of 2026.

A budget of $54.5 million has been allocated for these improvements, with funds sourced from a combination of developer contributions, the City's Type B sales tax, City-issued Certificates of Obligation bonds, and contributions from Williamson County. The investment underscores the city's commitment to not only enhancing vehicle traffic flow but also to encouraging pedestrian mobility as an important facet of the local infrastructure.

For those interested in tracking the progress of this project or to learn about other transportation projects in the works for Round Rock, detailed information can be found on the city's transportation page. Projects include the expansion of Gattis School Road, the Old Settlers Extension, the widening of Red Bud Lane North, the Wyoming Springs Extension Segment 1, and the Harrell Parkway Reconstruction, each designed to improve traffic, upgrade intersections, and pedestrian accommodations across this growing city.
