What Solano Transportation Authority does

Solano Transportation Authority (STA) is a Joint Powers Authority established under California law and the statutorily designated Congestion Management Agency and transportation planning authority for Solano County. Headquartered at 423 Main Street in Suisun City, California, with 36 employees, STA serves all seven cities of the county (Benicia, Dixon, Fairfield, Rio Vista, Suisun City, Vacaville, and Vallejo) plus unincorporated areas. Its core function is end-to-end transportation project delivery and program administration: STA plans, funds, and oversees capital infrastructure such as the I-80 Express/Managed Lanes ($123.4M TCEP award), the I-80 Westbound Truck Scales replacement ($129M TCEP award), the SR-37/Fairgrounds Drive Diverging Diamond Interchange ($24.9M construction contract, February 2025), and the Solano Rail Hub multi-modal project, while also operating service programs including Solano Mobility, Solano Express, Safe Routes to School (engaging 80 schools countywide), the EV Program, Clean Air, the Abandoned Vehicle Abatement Program, and Suisun Microtransit door-to-door transit ($2.00 general / $1.00 discounted fare). STA is governed by an STA Board with member agencies, Technical Advisory Committee, and citizen advisory committees, and operates with 19 consecutive fiscal years of clean audit opinions and no material weaknesses.

STA's technology stack is conventional public-sector transportation tooling rather than a proprietary platform: transportation planning and mobility management infrastructure, the Solano Travel Demand Model, GIS data systems, and FasTrak/toll technology for the I-80 managed lanes corridor (operated in partnership with BAIFA). STA does not operate an app, API, or SDK, and holds no patents or trademarks. Its revenue model is overwhelmingly government-funded: it receives formula and competitive grants from USDOT/FHWA, Caltrans, the California Energy Commission, and the Metropolitan Transportation Commission; administers dedicated vehicle registration surcharges ($4 TFCA, $1 DMV AVA) channeled through BAAQMD and YSAQMD; collects FasTrak toll revenues on I-80 Express Lanes (reinvested in the corridor by statute); and charges transit fares on Suisun Microtransit. Its go-to-market is direct-to-consumer through public board meetings, community task forces, the monthly STATUS newsletter, the Solano Mobility call center (1-800-535-6883), and program-specific websites (sta.ca.gov, solanomobility.org, solanosr2s.ca.gov), with delivery executed through member agency transit operators and contracted vendors such as Transportation Concepts and Ghilotti Construction.

Direct peers

• Bay Area Infrastructure Financing Authority (BAIFA): Joint powers authority that operates express-lane tolling systems across the Bay Area, including on STA's I-80 corridor. BAIFA is a direct operational peer and active partner — it runs the FasTrak tolling system that funds STA's managed-lane projects and pilots weekend tolling.
• Transportation Authority of Marin (TAM): Marin County's sales-tax-funded transportation authority. TAM is a direct peer to STA in scope and authority — both administer regional Measure funds, coordinate with Caltrans on highway projects, and partner jointly on the SR-37 corridor improvements from Marin to Solano.
• Napa Valley Transportation Authority (NVTA): County-level transportation authority for Napa County, California. NVTA is a direct peer with the same statutory mandate (congestion management, project programming, transit coordination) and is one of STA's named partners on the multi-county SR-37 improvement program.
• Alameda County Transportation Commission (Alameda CTC): Alameda County's transportation authority, administering Measure BB and federal/state funds for highway, transit, and active transportation projects. Alameda CTC is a direct peer to STA as a same-structure California county transportation authority operating in the same Bay Area funding ecosystem.
• Contra Costa Transportation Authority (CCTA): Contra Costa County's transportation authority, structurally analogous to STA as a JPA-funded county transportation planning and project delivery body. CCTA is a peer in administering a ½-cent sales tax, delivering managed-lane projects, and coordinating with MTC and Caltrans across the East Bay–Solano corridor.
• Sonoma County Transportation Authority (SCTA): California county transportation authority operating under the same JPA framework as STA. SCTA is a direct peer — STA and SCTA partner on the SR-37 corridor and both administer sales-tax Measure M/M funding for highways, transit, and active transportation within their respective counties.
• Capitol Corridor Joint Powers Authority (CCJPA): JPA managing Amtrak Capitol Corridor intercity rail service through Solano, Contra Costa, Alameda, and other counties. CCJPA is a direct peer — STA's Solano Rail Hub is designated as a key station in CCJPA's Vision Implementation Plan, tying STA's rail-mobility investments into CCJPA's broader network.

Broad incumbents

• Santa Clara Valley Transportation Authority (VTA): Multi-modal county transportation agency for Santa Clara County combining planning, highway, and transit operations. VTA is a broader incumbent peer — significantly larger than STA but operating the same combination of congestion management, project programming, and transit delivery that defines STA's mandate.
• Metropolitan Transportation Commission (MTC): Regional transportation planning and financing agency for the nine-county San Francisco Bay Area. STA is a sub-regional partner that channels MTC-administered funds (e.g., $100M RM3 commitment) into Solano County projects, making MTC STA's parent-scale peer in funding allocation and Plan Bay Area coordination.

Regional players

• San Mateo County Transit District (SamTrans): Multi-modal transit district for San Mateo County operating bus, paratransit, and rail services. SamTrans is a regional peer — directly comparable to STA's Solano Express and Suisun Microtransit operations, though SamTrans is larger and focused on a transit-heavy ridership base rather than highway capital programming.
