Roads and Highways

I-15 Express Lanes

The 20-mile, state-of-the-art Express Lanes facility between SR 163 and SR 78 was completed in January 2012. Funded in part by the TransNet half-cent sales tax, the $1.4 billion project is designed to maximize capacity, relieve congestion, and “wow” travelers.

The I-15 Express Lanes feature four lanes with a moveable barrier for maximum flexibility (similar to the moveable barriers on the San Diego-Coronado Bridge); multiple access points to the general purpose highway lanes; and direct access ramps for high-frequency Rapid service.

The Express Lanes were built in three segments. The Middle Segment was the first to be constructed and opened to traffic in two phases. The first phase from SR 56 to Rancho Bernardo Road opened in September 2008. The second phase from Rancho Bernardo Road to Centre City Parkway opened in early 2009. The North Segment and the South Segment opened to traffic in 2011 and 2012, respectively.

Several bridges along this stretch also were modified to accommodate the Managed Lanes. The Pomerado Bridge, which reopened for public use in January 2007, was demolished and completely rebuilt in just nine months. The new and improved bridge features four lanes; a pedestrian and bike path; a signalized intersection at the west end; upgraded seismic standards; and aesthetic improvements to coordinate with other construction in progress on I-15.

The innovative Express Lanes provides vanpools, carpools, buses, and FasTrak® customers with a smoother trip along the booming corridor; and also relieves demand on the general purpose lanes.

In 2010, a 20-mile section of I-15 from just north of SR 52 in the City of San Diego to SR 78 in the City of Escondido was selected as one of two pilot sites in the nation to develop, implement, and operate an Integrated Corridor Management (ICM) system. The cutting-edge technology identifies and determines how freeway, arterial, and transit networks can be managed together to improve mobility and maximize system efficiency.

Residents are invited to monitor progress on I-15 with the TransNet Dashboard, an interactive, online reporting tool that displays how TransNet dollars are being spent. The dashboard is a key element of — the region’s window to in-depth project descriptions, construction schedules, public meeting notices, maps, news releases, and other information.
