As part of the work, Carlsbad residents can expect lane closures and noise due to ongoing construction activity in the median and shoulders of I-5 in both directions.
The increased noise is due to heavy machinery used to grind existing pavement. Work will take place from 9 p.m. to 5 a.m. because of the lane closures.
Crews will attempt to minimize noise and impacts to nearby communities, and motorists will be alerted with signage and traffic controls.
The new lanes, part of the final phase of the Caltrans and SANDAG Build NCC (North Coast Corridor) program, are expected to be open to traffic in 2022.
Once the $870 million package of highway, rail and environmental improvements is complete, it will include:
- the new carpool/HOV lanes on I-5, between Lomas Santa Fe Drive in Solana Beach and SR-78 in Oceanside.
- Rail double tracking
- New bike and pedestrian trails, and
- Restoration of the San Elijo Lagoon
