AUSTIN (KXAN) — Two lanes along a busy section of a south Austin road are closed Friday morning due to a “partial road cave-in,” according to a tweet from the Austin Transportation Department.

The department said crews are shutting down two of the three eastbound lanes of West William Cannon Drive from Menchaca Road to Woodhue Drive. The lanes may remain closed through next week, the city warned.

The Austin Public Works Department crews said sediment movement caused the collapse under the road asphalt, which happened after the heavy rains earlier this week.

Staff from Austin Public Works’ Office of the City Engineer were on site Friday investigating the cause of the road damage and determining a solution. Repair work has begun and is expected to wrap up September 3.

Two of three eastbound travel lanes and the sidewalk will remain closed until then. Drivers are advised to take an alternate route during this time.

No vehicles or people were harmed due to the cave-in.
