Construction Impacts on the Trail

Content Image
Here are any impacts to the Ann & Roy Butler Trail that could cause detours or slowdowns in your daily route.

July 22, - August 2024

Waller Creek Confluence

Over the next several months, users of the Ann and Roy Butler Hike and Bike Trail are urged to slow down and be prepared to stop when approaching Waller Creek. A series of detours will be in place to construct new lattice bridges and the Lagoon Overlook and Leaf Deck for The Confluence, the second phase of the Waterloo Greenway.

The first detour is scheduled to start Monday, July 22, and last through the end of August, weather permitting. While this detour is in place, the construction crew will be installing a new lattice bridge and preparing a temporary creek crossing for later detours. Subsequent detours will differ on the route over the creek.

The first detour will route users of the trail onto a temporary, 12-foot wide, crushed granite trail just east of the existing bridge over Waller Creek. The temporary trail will be fenced on either side, and users will continue to cross Waller Creek on the existing bridge.

Periodically, bicyclists and pedestrians may need to stop briefly to allow construction traffic to cross the trail. There will be a flagger, and gates will keep trail users separate from vehicular traffic. Work hours are 7 a.m. to 7 p.m. Monday through Friday, with occasional weekend work.

Longhorn Dam

The Austin Transportation and Public Works Dept. will be issuing the notice to proceed (NTP) to the contractor for the new Longhorn Dam pedestrian bridge construction project on July 1, 2024. You will start to see activity on this date or shortly after.

There will be an 18-month detour to the Butler Trail during this construction time that will direct Trail users across Pleasant Valley Rd and back again at two locations and along the east side of the bridge. The detour will continue along Canterbury St. to Pedernales and connect to the Trail. Both crossings at Pleasant Valley Rd will be at pedestrian hybrid beacons.
