Public Transit

I-15 Rapid


In June 2014, a new Bus Rapid Transit (BRT) service, called Rapid, began service along the I-15 corridor. This high-frequency transit service offers increased reliability and customer convenience, similar to the services of a light rail system. Rapid features include transit signal priority, digital displays announcing next vehicle arrival times, modern shelters, and fewer stops. Other planned transit improvements will support Rapid services, connecting residential areas to major employment centers and creating a vast network of quick and efficient public transit throughout the region.

In addition to providing faster service and increased routes, the I-15 Rapid service includes 29 new vehicles with improvements designed to make the ride more comfortable, accessible, and convenient for passengers. Rapid vehicles are designed to streamline and accelerate the boarding process by featuring multiple doors, low-floor designs, and fare boxes that accept Compass Cards. Additional design features, such as comfortable seating and larger windows, improve ride quality. Automated systems provide announcements of station stops and other transit information.

Two new Rapid services began in 2014:

  • Rapid Route 235 is a new all-day, all-stops service (15-minute frequency in peak-hours and 30 minute frequency off-peak) that runs from Escondido Transit Center to Downtown San Diego via I-15. This service started on June 8, 2014.

  • Rapid Route 237 is a new weekday, extended peak hour service (15-minute frequency) that runs from Rancho Bernardo Transit Station to UCSD via I-15. This service began on October 13, 2014.

    These new Rapid routes will complement existing and new MTS regional and local transit services, including Rapid Express 280, Rapid Express 290, and Mid-City Rapid 215.

    The new Rapid services will use capital investment projects throughout the corridor:

  • The I-15 Express Lanes is a 20-mile facility that extends from SR 78 in Escondido to SR 163 and provides four express lanes separated from general purpose lanes. These express lanes provide free access for transit, carpools, vanpools, motorcycles, and permitted clean air vehicles; solo drivers may use the lanes for a fee with a valid FasTrak® account.

  • Direct Access Ramps (DAR) provide direct access to and from the I-15 Express Lanes, allowing users to avoid congestion at general traffic freeway on-ramps. DARs connect the I-15 directly to the Escondido Transit Center, Del Lago Transit Station, Rancho Bernardo Transit Station, Sabre Springs/Peñasquitos Transit Station, and San Diego Miramar College Transit Station.

  • Upgraded transit stations at Escondido Transit Center, Del Lago, Rancho Bernardo, and Sabre Springs/Peñasquitos, Kearny Mesa, Mid-City, Downtown San Diego, and a new San Diego Miramar College Transit Station, include modern shelters, next vehicle arrival signs, enhanced staging areas, improved lighting, security cameras, and secure bicycle parking. Additional corridor improvements along Clairemont Mesa Boulevard and Mira Mesa Boulevard include Transit Signal Priority improvements which offer increased reliability in service schedules.
