San Diego MTS bus system

The San Diego MTS bus system is a public transport bus service serving San Diego County, California. It is part of the San Diego Metropolitan Transit System (MTS). The system operates 97 bus routes in San Diego and the rest of the southern half of the county. ^{[1] [2]} There are 85 "MTS Bus" fixed-route services, 9 "Rapid" bus rapid transit routes, and the "MTS Access" paratransit service.

Routes are operated by private contractors and by the San Diego Transit Corporation (SDTC), a subsidiary of MTS. SDTC operates 27 routes based out of downtown San Diego (Imperial Avenue Division), Transdev operates 74 routes based out of Chula Vista (South Bay Division) and El Cajon (East County Division), and operates the "MTS Access" paratransit service that are operated with mini-buses based out of Kearny Mesa (Copley Park Division).

All buses and division facilities, even those used by contractors, are owned by MTS. MTS serves San Diego proper and the surrounding East County and South Bay regions, ^[3] while the North County area is served by the North County Transit District (NCTD)'s BREEZE bus system. ^[4]
