Paving, traffic light installation closes part of busy El Cajon Blvd.

SAN DIEGO — A stretch of El Cajon Boulevard running through Normal Heights and City Heights was closed early Wednesday so crews could begin installing new traffic signals. The off-ramp from northbound state Route 15 to El Cajon Boulevard will also be closed  from 9 a.m. to 3 p.m. for paving work.

Overnight closures of El Cajon Boulevard’s lanes and sidewalks in both directions between 38th Street and Marlborough Avenue are scheduled through Thursday. During work hours from 9 p.m. to 5 a.m., the onramps and offramps from SR-15 to El Cajon Boulevard also will be closed intermittently, according to the San Diego Association of Governments.

Motorists will be detoured around the closure via 38th Street, Marlborough Avenue and Meade Avenue. The closures will also affect Metropolitan Transit System buses.

The paving work on the off-ramp is expected to only take one day, officials said.

Travelers were advised to allow extra time or consider an alternate route to their destination.

The work is part of a $65 million effort to build freeway-level transit stations along the SR-15 at University Avenue and El Cajon Boulevard and transit-only lanes on the highway from north of Interstate 805 to south of Interstate 8. Transit officials said the SR-15 Mid-City Centerline Rapid Transit Stations Project is expected to be finished next year.
