If you would like to receive e-mail updates, please send an email to roads@wilco.org with the specific corridor you are interested in and "Updates” in the subject line. 

The corridors are being studied as part of the Long-Range Transportation Plan (LRTP). The LRTP is a guiding document that Williamson County is responsible to develop to plan for accommodating transportation and mobility now and in the future. This plan has been updated and will continue to be updated based on current needs, population projections, anticipated future mobility needs, and safety of Williamson County. The planning process to develop the LRTP involves working with the public, cities, neighboring counties, and transportation and planning agencies to gather input and coordinate connectivity and mobility. 

The current amendments to the LRTP outline a network of roadways that will improve safety and mobility across the County, and include a maps of proposed controlled access facilities and proposed arterial facilities. The locations of the controlled access facilities and arterial roadways are conceptual only to show general locations and connections needed. Final alignments for each route will be determined through appropriate planning and environmental studies.

Engineering firms have been hired for each of the studies to conduct public involvement, environmental studies, preliminary engineering, and schematic development. Construction funding has not been identified at this time.
