A popular Interstate 5 on-ramp in Encinitas will close for the entire weekend as crews continue construction on the San Elijo Lagoon highway bridge.
The southbound I-5 on-ramp from Manchester Avenue will close from Friday, Nov. 1, at 9 p.m. through Monday, Nov. 4, at 5 a.m., according to the San Diego Association of Governments.
Crews will switch the ramp over to a new location that better aligns with southbound exterior San Elijo Lagoon highway bridge.
A detour via I-5 north to Birmingham Drive will be available for drivers.
Construction on the San Elijo Lagoon highway bridge will add new carpool lanes in each direction and a new bike and pedestrian suspended bridge, SANDAG said. It will also improve tidal flow for the lagoon below.
The project is part of Build NCC, a collaborative effort between SANDAG, Caltrans, and the U.S. Department of Transportation.
