(KRON) — The full highway closure of westbound Interstate 80 between I-780 and State Route 4, including the Carquinez Bridge has reopened Monday evening, according to Caltrans. The section of roadway was closed following major pavement repair work during Labor Day weekend.

Caltrans made significant progress throughout the long weekend and the roadway reopened a day earlier than previously expected.

Crews completed the concrete pour on the number three lane and worked to rip out the old concrete from the number one lane.

Caltrans crews also performed vegetation management work along the westbound lanes.

The full highway closure for westbound I-80 began Thursday at 9 p.m. “The roadway has become worn and in need of major repairs due to decades of high traffic use,” according to Caltrans.
