183A Trail

A 7-mile long path bordering 183A Toll from south of Brushy Creek Road to Hero Way.

The 183A Trail is a paved, 10-foot-wide, dedicated bicycle and pedestrian path. It connects to Williamson County’s Brushy Creek Regional Trail with a pedestrian bridge and includes a trailhead with exercise equipment. The trail also connects to the Cedar Park Recreation Center via a path at Whitestone Boulevard.

The 183A Phase III Project will extend the shared use path northward from Hero Way to Seward Junction Loop.

Accessing the Trail

Trail users do not have to take the 183A Toll to access the trail. Drivers can access the Brushy Creek Trailhead using the southbound general-purpose lanes from Brush Creek Road/Cypress Creek Road adjacent to the toll. Parking is available.
