The three left lanes on northbound Interstate Highway 880, just south of Interstate Highway 980, are open to traffic after multiple collisions blocked all lanes in Oakland this morning, the California Highway Patrol said.
The first accident was reported at 4:51 a.m., Officer James Evans said.
A Sig-alert was issued at 5:18 a.m. after another collision was reported, Evans said.
The fast lane was reopened at 5:28 a.m., and the two middle lanes reopened by 5:50 a.m., he said.
At least eight cars were involved in the collisions, Evans said.
It is unknown when the slow lane will reopen.
