October 19, 2026 Construction Update

Crews refreshed lane markings on McKinney Falls Parkway and William Cannon Drive in the active work zone. This work was undertaken in response to a community request to improve lane markings in the area. Travelers will see new markings that further clarify lane assignments through the intersection, improving safety.

Anticipated completion: Early 2027. The schedule is subject to change.

Prepare for temporary lane closures in the area. Follow posted signs and allow extra travel time.

October 5, 2026 Construction Update

Additional lane closures will begin this week on northbound McKinney Falls Parkway. This is in addition to the lane closure mentioned below that began in late September 2026.

Please approach the area with caution and avoid distractions to help keep work crews safe. Minor delays are expected as traffic is reduced to one through lane.

Anticipated completion: Early 2027. The schedule is subject to change.

September 21, 2026 Construction Update

Beginning this week, crews will close the outside lane of McKinney Falls Parkway just south of William Cannon Drive. This temporary lane closure is to allow construction crews to complete a water line upgrade to improve supply and system reliability for Austin Water customers in the area.

Drivers should expect minor delays and are encouraged to plan additional travel time or use alternate routes when possible. Please approach the area with caution and avoid distractions to help keep work crews safe.

Anticipated completion: Early 2027
