Caltrans and SANDAG crews are planning an overnight ramp closure Thursday as part of the ongoing San Elijo Lagoon Highway Bridge Replacement Project.
At 9 p.m. that day and continuing until 5 p.m. Friday, a full closure is planned for the southbound I-5 off-ramp to Manchester Avenue, officials said Wednesday.
During the closure, crews will reposition K-rail (concrete barriers), switch the ramp over to a new alignment and stripe the ramp road surface.
A detour will be in place taking motorists around this closure via I-5 south to Lomas Santa Fe Drive in Solana Beach.
During November, multiple ramp closures also are set at the I-5/Manchester Avenue interchange, ranging from overnight closures to weekend closures.
The Build NCC project team will continue to send email notices alerting residents to upcoming closures and associated detours or other traffic impacts.
“These closures will play a key role as they facilitate continued San Elijo Lagoon highway bridge construction and provide space necessary for an upcoming traffic switch onto the two new exterior northbound and southbound highway bridges (anticipated in early-2020),” said the San Diego Association of Governments.
Build NCC is a collaborative effort between SANDAG, Caltrans and the U.S. Department of Transportation. The first phase of construction is in Solana Beach, Encinitas and Carlsbad as part of the North Coast Corridor Program.
Build NCC includes extending the existing carpool lane on Interstate 5 in each direction from Lomas Santa Fe Drive to state Route 78, double tracking the rail line and replacing the highway bridge at the San Elijo Lagoon, restoring the San Elijo Lagoon and installing nearly seven miles of new bike and pedestrian trails.
Build NCC work began in early 2017 and will be complete by 2022.
