What Tri Delta Transit does

Tri Delta Transit, legally the Eastern Contra Costa Transit Authority (ECCTA), is a California public transit authority operating since 1977 across Eastern Contra Costa County. It runs a multi-modal service network consisting of 14 fixed bus routes (local and express numbered 200X/201X and 360-377), the Tri MyRide on-demand microtransit service (operating across three zones — Pittsburg/Bay Point, Antioch/Oakley, and Brentwood — powered by Via's platform at $2 per ride), ADA paratransit, and Senior paratransit. Fixed route buses are fully accessible with wheelchair lifts, ramps, and audio stop announcements. The agency serves a diverse rider base including general commuters, seniors, people with disabilities, students, and low-income individuals through programs like LIFE (Low Income Fare Equity) and Clipper START. Customer access is delivered through fixed bus stops, an administrative office in Antioch, the Tri MyRide mobile app (iOS/Android), paratransit phone reservations, Clipper Card fare payment, and an online ticket-by-mail system.

The business model combines farebox revenue with public funding. Fares are transactional and modest: $2.00 local / $2.50 express for general riders, with reduced rates for seniors and people with disabilities, plus day passes ($3.75), 20-ride passes ($33), and 31-day passes ($57). Paratransit fares run $2.75 per one-way trip. The bulk of operating funding comes from federal, state, and local government transportation allocations, and the agency publishes financial statements and audits on its website. Strategic partnerships are central to operations: Keolis operates services under contract; Uber, Lyft, and United Med Transportation deliver the Mobility on Demand program for ADA customers (subsidizing up to $14 per ride); BART, County Connection, LAVTA, and WestCAT enable regional connectivity and the One Seat Regional Ride program. As of 2026 the agency is navigating a fiscal cliff budget crisis that resulted in service reductions effective August 9, 2026, including discontinuation of two routes and frequency cuts across multiple lines, with Tri MyRide increasingly used as a replacement service in lower-density zones.
