The 45SW Corridor
To continue the Mobility Authority’s commitment to offering multimodal transportation options to Central Texans, the 45SW Trail is a 4.5-mile bicycle and pedestrian shared-use path from FM 1626 to MoPac and Escarpment Blvd. This path helps to encourage alternative transportation, as well as active and healthy recreation for the public.
The 45SW Trail Experience
A large portion of 45SW is located in the Edwards Aquifer Recharge Zone, which is an environmentally sensitive region for karst (cave) features that serves as a vital component of the community's drinking water resource.
The Mobility Authority installed 14 informative and highly-visual signs along the 4.5-mile 45SW Trail to share the rich history and natural wonders of the Hill Country and Edwards Aquifer, including how the community can help protect our region’s water source.
We took that effort even further by introducing a new mobile app; Trail Explorer by CTRMA, which enhances the signs by offering a narrated experience in English and Spanish, as well as six augmented reality animations. With this app, users can watch a prehistoric sea creature animate in life-size form right before their eyes, witness the majesty of a towering Live Oak Tree as it grows from the ground up or take a deeper look at the caves below the surface in Central Texas, and much more.
Trail Explorer by CTRMA is an innovative mobile app experience that expands upon the purpose of the 45SW Trail. The app is free to download and adds an interactive and fun, while highly educational, element to the trail that the entire family will enjoy.
Additional features of the app include GPS guidance to help users navigate the trail and alert users to upcoming experiences. Users can also take photos with the augmented reality animations to capture and share the journey with their friends and family.
While we’re considering expanding the app to some of our other trails in the future, currently the Trail Explorer app only functions once you’re out on the 45SW Trail and scan the brackets located on the educational signs to launch the experiences.
There are two main trailheads to access the 45SW Trail with parking provided at each. Trail users do not have to take the 45SW Toll to arrive at the two main trailheads of 45SW Trail. Access the trail through the MoPac Trailhead or the Bliss Spillar Trailhead.
Dogs are welcome, but must remain on-leash.
