State Highway 45 Southwest

State Highway 45 Southwest is a four-lane toll road located around sensitive environmental areas, including the 1,250-square-mile Edwards Aquifer Recharge Zone. The Edwards Aquifer is the key supplier of water in San Antonio and parts of Austin.

In addition to building in an eco-friendly setting, State Highway 45 is adjacent to a residential neighborhood. In order to minimize disruption to the neighborhood and keep residents safe, McCarthy used social media to coordinate with the local Home-Owners Association and notify residents of major changes.

Part of Highway 45 was built out of sequence to accommodate safe passage for school buses. The McCarthy team coordinated with the local school district and residents in order to plan around school bus routes.
