1 dead in crash on Cummings Skyway near Martinez

One person died and another was seriously injured in a two-car crash this morning near Martinez in unincorporated Contra Costa County, the California Highway Patrol reported.

CHP officers responded to the crash at 10:43 a.m. in the area of Cummings Skyway just north of state Highway 4. 

A Ford sedan had drifted off the roadway and onto a dirt shoulder when it overcorrected into oncoming traffic and crashed its passenger side into a Nissan Xterra, the CHP said.
