The California Highway Patrol has issued a severe traffic alert Thursday morning after an accident closed the northbound I-238 connector ramp to northbound I-880 in San Leandro.
The closure was first reported at about 10:45 a.m. as crews worked to remove debris from an earlier accident on the connector ramp. As of 11:15 a.m., CHP reports that tractor trailers should take northbound I-238 to southbound I-880 and turn around at Winton Ave in Hayward.
Trailers are being allowed to use westbound I-580 through Oakland until further notice. Motorists are advised to expect delays and to use alternate routes to avoid the area.
CHP estimates that the road will be re-opened at 3pm.
