San Diego Metropolitan Transit System (MTS)

As the largest provider of public transportation in San Diego County, the Metropolitan Transit System (MTS) is committed to providing exceptional service to the people of the San Diego region. Every year more than 95 million people ride MTS buses and Trolleys. We have more than 80 fixed-route bus lines and 54 miles of Trolley service. Our fleet of compressed natural gas buses and electric Trolleys allow MTS to be one of the greenest companies in San Diego. As our region continues to grow, there will be a greater dependence on public transportation to help achieve mobility goals. MTS is adding three new Bus Rapid Transit lines to provide high-speed, limited-stop bus service to SDSU, Otay Mesa, Rancho Bernardo and Escondido. And plans are progressing to expand the Trolley 11 miles from Old Town to UCSD and University Town Center. MTS is one of the most modern and dynamic public transportation systems in North America and we would love for you to help us achieve our goals!
