(KRON) — Work on the eastbound I-580 in Livermore has been completed and four lanes of the five-lane highway have reopened, according to Caltrans. Caltrans crews shifted the highway to the left at a spot where a retaining wall collapsed to open the four lanes.

The section of the 580 just east of North Flynn Road has been under repair for several days as crews work to fix a crack in the roadway along with the retaining wall collapse. The shift is temporary until a permanent fix is installed, Caltrans said.

The five-lane highway shifts to four lanes as motorists approach North Flynn Road on eastbound 580. Repair efforts along the section of roadway have been ongoing for several days and have been further complicated by the latest in a series of atmospheric river storms that have struck the Bay Area.
