Introduction

View MapThe I-15 Express Lanes corridor is the most innovative highway in San Diego County. It speeds commutes. It fosters public transit. It encourages shared ridership. It offers benefits no matter how you travel. The 20-miles I-15 Express Lanes project, running from SR 78 in Escondido to SR 163 in San Diego, is now complete. View Fact Sheet.

Built in the center of the I-15 freeway, the new Express Lanes help all travelers. Travelers using the Express Lanes have reliable travel times. And travelers in the general purpose lanes have less traffic congestion.

There’s no entry fee for carpools and vanpools, bus riders, motorcycles, and certain permitted clean air vehicles to enjoy more predictable travel times on the Express Lanes. The new Rapid transit service, operated by Metropolitan Transit System (MTS), utilizes the Express Lanes to connect North County communities to regional employment and leisure destinations and to other transit modes such as the COASTER and SPRINTER providing a much more efficient and convenient transit option.

For solo drivers, using the Express Lanes takes three easy steps: Set up a FasTrak® account, place a transponder on your windshield for electronic tolling, and start driving.

The I-15 Express Lanes have been nationally recognized for their innovative designs. They are the first section of a regional system of interconnected Express Lanes. Their highlights include:

• More than 20 access points that give travelers a wide range of options of where to enter or exit the lanes so they can easily reach their destinations.

• Five direct access ramps that allow travelers to enter the Express Lanes from surface streets. New and improved transit stations are located at these ramps to support improved public transit options.  

• Access to motorists 24 hours a day, seven days a week, in both north and south directions.

The cost of the project is $1.4 billion and it was funded in part by TransNet, a half cent sales tax approved by San Diego region’s voters in 2004, and other state and federal funds.

Construction Advisories

Although the I-15 Express Lanes, transit stations, and direct access ramps are fully opened, closures may take place near Mira Mesa to complete work on the Mira Mesa DAR.
