SAN DIEGO–The northbound Interstate 5 (I-5) connector ramp from the San Diego-Coronado Bridge will close through Thursday night from 9 p.m. to 5 a.m. for electrical work.

Signs will be posted detouring motorists to the National Avenue off-ramp and turn right, continue straight to Cesar E. Chavez Parkway and turn right onto Kearney Avenue/19th Street to the 19th Street northbound I-5 on-ramp.

The work is part of a $14.6 million project to upgrade the electrical systems on the San Diego-Coronado Bridge. The existing electrical systems are approximately 50 years old and much of the current equipment is outdated. The upgrade includes replacing the existing bridge light fixtures to Light-Emitting Diode (LED) lights that are lower energy consumption. The project is expected to be completed by next summer.

Caltrans reminds drivers to ‘Be Work Zone Alert’ by avoiding distracted driving, paying constant attention to traffic, and slowing down when approaching work zones.
