The San Diego Association of Governments and Caltrans will begin a four-day, full weekend closure of southbound Interstate 5’s on-ramp from Manchester Avenue Friday to continue construction work.
Work crews will close the ramp from 9 p.m. Friday to 5 a.m. Monday morning to merge the existing ramp to its new alignment that will tie into the San Elijo Lagoon highway bridge. Motorists seeking to get on southbound I-5 at Manchester Avenue will be detoured up northbound I-5 to Birmingham Drive and re- routed back down the freeway.
The closure is one of multiple expected ramp closures at the interchange of I-5 and Manchester Avenue over the next six weeks, part of the San Elijo Lagoon Highway Bridge Replacement Project. The project will add carpool lands on both sides of I-5 over the lagoon and a pedestrian bridge linking the north and south sides of the lagoon.
The project is scheduled to be completed in 2021.
The closure is part of SANDAG’s Build NCC (North Coast Corridor) program, the first phase of a 40-year, $700 million effort to repair and expand vehicle and rail transportation infrastructure throughout the county. Build NCC, which began in 2017 and includes construction in Solana Beach, Encinitas and Carlsbad, is scheduled to be completed in 2022.
Once the full 40-year program is completed, SANDAG anticipates adding a total of 13 miles of new carpool and high-occupancy vehicle freeway lanes, 1 1/2 miles of doubled railroad track, seven miles of bike and pedestrian paths and more than 1,200 acres of restored and preserved coastal habitat land.
