State Route 125 (South Bay Expressway)

State Route (SR) 125 (South Bay Expressway) San Diego County

The South Bay Expressway (SR 125) officially opened on November 19, 2007. The 10-mile state-of-art toll road extends from SR 54 in Spring Valley to Otay Mea Road/SR 905 near the International boarder crossing. The South Bay Expressway is four lanes and has seven interchanages but may be expanded to meet future growth. Motorists traveling the new toll highway will be able to take advantage of the latest in high-tech toll collection, which allows tolls to be paid while driving at highway speeds using a FasTrak® electronic transponder mounted on their vehicle.

The construction of this express toll road is being made possible through an innovative public-private partnership, and is one of the first roads of its kind in California and the United States.
