LIVERMORE, Calif. (KGO) -- Caltrans closed two lanes of eastbound I-580 at North Flynn Road in Livermore for emergency road repairs on Monday.
On Tuesday, two eastbound lanes at Flynn Road remain closed in an area with few viable detours with only two lanes of traffic open causing significant delays.
Caltrans says this collapse has gotten worse Tuesday because of erosion that's causing the retaining wall to slide down the hill. They're worried about the rest of the freeway.
Video from Monday showed a crack down the middle of the lane.
"We've lost two lanes of eastbound 580 toward the Altamont pass in Livermore. Significant rainfall has come down and damaged a retaining wall -about 250 feet has to be replaced. It's also caused a crack on the mainline freeway and we can't have trucks riding over that part of the freeway," said Bart Ney, Caltrans spokesperson.
A team of engineers are analyzing the damage and there are concerns more lanes could be compromised.
Caltrans hopes to re-stripe the section of freeway when the weather dries out. But a long term fix could require rebuilding part of the road.
