The driver of a black El Camino opened fire on another vehicle on Interstate 80 in Hercules on Tuesday night, striking a person in the leg, police said. The incident is the latest in a string of roughly 20 highway shootings that have taken place in the Bay Area since November.

California Highway Patrol officials said the driver of a black Chevrolet El Camino with dark tinted windows opened fire on eastbound Interstate 80, west of Highway 4, at 9:16 p.m. A person in a nearby car was hit in the leg by the gunfire, and another vehicle’s windows were shattered by the shots.

The wounded victim was reportedly taken to the hospital, but it was unclear what condition the person was in.

Officials said an investigation is ongoing and that they will release further details as they become available.

Contra Costa County’s Highway 4 corridor has been the scene of nearly 10 similar shootings since June, prompting Pittsburg officials to have surveillance cameras installed along the highway in hopes of catching shooters. Leaders from at least four other nearby cities, including Hercules, plan to ask for state funding to install cameras on other highways.

Tuesday night’s shooting follows a late-afternoon highway shooting Sunday, in which a man opened fire on another driver during a road-rage incident on westbound Interstate 580 in Richmond before fleeing the scene, crashing into a pole and leaving his bumper behind with the license plate still attached.

That car was described as a gray 2005 Volvo S60 with license plate number is 7ENK356. No injuries were reported in that incident and no arrests have been made.

Last week, a woman was killed and a man was injured in a shooting on Highway 4 in Pittsburg.

CHP officials are asking anyone with information on any of the shootings to call them at (800) 835-5247.
