Trail Extensions Coming Soon

You may have noticed the signs along the interstate, or at trailheads in areas surrounding the San Elijo Lagoon. In conjunction with Caltrans, SANDAG, Transnet, North County Transit District, 511, California Fish and Wildlife, and the San Elijo Lagoon Conservancy, County Parks is gearing up for improved access along the north coast corridor.

The project, called Build NCC, launched late last year, following a kick-off event at the San Elijo Lagoon Nature Center. Speakers shared project highlights and a timeline, which is slated to occur over 5 years. 

A key component of the project is to build 10 miles of pedestrian and bike trail connections from Solana Beach to Encinitas. Named the North Coast Bike Trail, paths span in all directions including a new bridge suspended from the existing San Elijo Lagoon highway bridge. Also cool are the additions of a new pedestrian undercrossing at the south end of San Elijo Lagoon, better access at the Chesterfield Drive crossing, a trail connection between the North and South sides of the Lagoon near the Nature Center, and the construction of bike and pedestrian paths at the Interstate 5’s Encinitas Boulevard and Santa Fe Drive interchanges.

While work is being done, some trailheads are closed. Click here to view the closure map.

“Trail closures are not permanent, and they are necessary to enhance access for all trail users, as well as to further restore the lagoon,” said Jessica Cissel, Region Manager for County Parks along the Central Coast.

Smart construction, with longer bridges and fewer support piers, will allow for a wider water channel below – adding movement and growth to this unique estuarine environment under the Pacific Flyway.

“We’re using this as an opportunity to educate people about all of the interesting things that are happening here at the lagoon,” added Cissel, “by opening new nature center exhibits, hosting Family Fun Days and encouraging kids to explore the nation’s most popular TRACK Trail.”  

Nearby, San Dieguito County Park has beefed up their program offerings with a handful of new activities like “Coffee with the Ranger” and “Survival School.” TRACK Trails exist in both the upper and lower park to meet the interests and abilities of all young patrons, along with roughly 5 miles of multi-use trails.
