SAN DIEGO — Chula Vista motorists are advised to avoid Telegraph Canyon Road at Interstate 805 (I-805) for a 56 hour closure this weekend, according to Caltrans. Telegraph Canyon Road near the I-805 ramps will be reduced to one lane in each direction beginning Saturday at 3:00 a.m. through Monday at 11:00 a.m.

The lane reductions are needed for seismic retrofit work on the Telegraph Canyon Bridge beneath I-805. I-805 will remain completely open.

Motorists traveling through the construction zone can expect delays and occasional full closures as equipment is moved. Motorists are urged to plan ahead and take alternate routes to avoid the congestion.

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