Road closures will affect late-night drivers on Toll 183A at Hero Way in Leander this weekend.

From June 7-10, road closures will occur between 9 p.m. and 5 a.m. in northbound and southbound lanes, according to a June 6 Central Texas Regional Mobility Authority release.

The rolling closures will run in 15-minute segments simultaneously on main lanes and frontage roads. Closures are expected through the morning of June 10, but work may last through the morning of June 11, said Dee Anne Heath, the Mobility Authority's director of external affairs. Message signs will notify drivers of anticipated delays, according to the release. Drivers should use caution and consider alternate routes.

Closures are related to new transmission lines over the toll road and will be implemented by the Lower Colorado River Authority.
