RENDERING COURTESY TEXAS DEPARTMENT OF TRANSPORTATION

tra c on the road. Additionally, the city will com- plete studies on Serene Hills Drive to address concerns about speeding and tra c build up at the Serene Hills and Flint Rock intersection, Molis said. “We’ve done some tra c studies on [Flint Rock] to look at the volume and capacity of the road. Our engineer tells us that, as of now, the road does have the capacity,” Molis said. “But as part of our long-term thoroughfare plan, we do show that road being wid- ened to a four-lane road.” LTISD is also anticipating comple- tion of its Vail Divide extension in early 2023, which will allow residents to access Hamilton Pool Road through a road near Bee Cave Middle School
both county and city jurisdiction, such as Flint Rock, Molis said. For Bee Cave, working with TxDOT on signal optimization at key inter- sections has alleviated a signi cant amount of tra c by making the lights turn quicker, Jones said. Addi- tionally, the city is working to gain full control of its tra c signals, he said. “If we have more autonomy over the lights, we can see where tra c is becoming congested at certain times and adjust those lights ourselves to get tra c owing more easily,” Jones said.
instead of waiting at the light at the intersection on Hwy. 71, according to the district. Upon completion, TxDOT will hand the project over to Travis County for continued maintenance. However, the problem extends beyond the realm of far western Travis County. A TxDOT project to improve safety and mobility on Loop 360 recently began. TxDOT plans to improve nine intersections that collectively will provide congestion relief along the road. The next planned step of the proj- ect is set to begin in 2026 and includes work at the intersection at RM 2222, including a new diverging diamond interchange. Work began at West- lake Drive and Cedar Street in June
to remove tra c signals on the Loop 360 mainlanes and add an underpass at both locations. Developing solutions Although coordination between so many entities for safety improve- ments may be di cult, it is possible, as shown by Lakeway and Bee Cave’s approach toward handling school tra c, Jones and Molis said. In Lakeway, the city has worked to build close connections with its area engineer for TxDOT to work on roads such as RM 620 by building additional turn lanes and managing tra c light timing. Similarly, the city is building relationships at the county level to address problems with roads having
