I-5 ramp closure in Encinitas during weekend of July 10-13

This summer, the Caltrans and SANDAG Build North Coast Corridor (NCC) team began a series of weekend on- and off-ramp closures along Interstate 5 (I-5) in Encinitas and Carlsbad. These closures will allow crews to realign the ramps to accommodate two new Carpool/High Occupancy Vehicle (HOV) Lanes, one in each direction on I-5 between Birmingham Drive in Encinitas and Palomar Airport Road in Carlsbad.

The next weekend ramp closure will begin Friday, July 10, at 9 p.m., and reopen on Monday, July 13, at 5 a.m. at the northbound I-5 on-ramp from Encinitas Boulevard.

Detour signage will be in place to guide motorists around this closure via southbound I-5 to Santa Fe Drive to access northbound I-5.

During the next 18 months, weekend ramp closures are scheduled along I-5 at the following locations: Birmingham Drive; Santa Fe Drive; Encinitas Boulevard; Leucadia Boulevard; La Costa Avenue; Poinsettia Lane; and Palomar Airport Road.

All closures will follow the same schedule, closing on Friday evening at 9 p.m. and reopening Monday morning at 5 a.m.

Each closure is expected to occur once at each ramp location, and only one ramp will be closed on any given weekend.

Weekend ramp closures reduce long-term construction impacts to immediate surrounding neighborhoods and businesses and allow crews to more safely and continuously complete ramp realignment work. Nearby residents and businesses can expect daytime and overnight construction noise and lights. Crews will work to minimize noise and impacts to all nearby communities, and motorists will be detoured with signage and traffic controls.

To ensure safety for both motorists and highway crews during I-5 construction, drivers are reminded to “Drive 55 on the 5” in the Build NCC construction zone and that traffic fines are doubled in construction zones.

The SANDAG operated Motorist Aid service for roadside assistance can be easily accessed by dialing 5-1-1 anywhere in San Diego County.

Additionally, the “Move Over” law requires all drivers to move over a lane or, if they are unable to do that safely, slow down when they see amber flashing lights on Caltrans vehicles, law enforcement and emergency vehicles, and tow trucks.

About Build NCC

Build NCC is a collaborative effort between Caltrans, SANDAG, and the U.S. Department of Transportation. The first phase of construction began in the cities of Solana Beach, Encinitas, and Carlsbad as part of the North Coast Corridor Program.

Build NCC includes extending the HOV lanes on I-5 in each direction from Lomas Santa Fe Drive to State Route 78, double tracking the rail line at the San Elijo Lagoon, replacing the highway and rail bridges at the San Elijo Lagoon, restoring the San Elijo Lagoon, and constructing nearly seven miles of new bike and pedestrian trails.

Construction on Build NCC began in early 2017 and is expected to be completed by 2022.
