Montebello Bus Lines began on 28 July 1931, with a small lot on the corner of Greenwood Avenue and Olympic Boulevard, where the four buses the agency operated were housed.

Three years later, in 1931, the City purchased the route back from the Motor Transport Company, and Montebello Bus Lines was born.

Montebello Bus Lines serves 15 communities, providing transport to 8 million passengers on an annual basis.

This reservation-based service utilizes shuttles that meet the Metrolink's arriving schedule in the morning and take passengers to major employment centers.
