Bi-State Development Agency and Metro Transit

Bi-State Development is the compact agency that operates Metro Transit — the primary public transportation system serving the St. Louis metropolitan region — and holds authority that crosses state lines into both Missouri and Illinois. Established by an interstate compact, the agency functions as a regional quasi-governmental body responsible for bus, light rail, and specialized transportation services. Understanding how Bi-State Development is structured, how it relates to Metro Transit, and where its jurisdictional boundaries fall is essential for anyone engaging with regional transportation policy, funding mechanisms, or service delivery in the St. Louis area. Broader regional governance context is available on the St. Louis Metropolitan Area Governance reference, and a general overview of civic functions is accessible from the site index.

Definition and scope

Bi-State Development Agency was created under the Bi-State Development Agency Compact, a congressionally approved interstate agreement between Missouri and Illinois (7 U.S.C. App., Public Law 86-303, enacted 1959). The compact authorizes the agency to plan, construct, and operate transportation infrastructure across a defined district that spans the Missouri portion of the St. Louis metropolitan area and the Illinois portion in the Metro East region.

The agency's legal name is Bi-State Development Agency of the Missouri-Illinois Metropolitan District. "Metro Transit" is the operating brand — not a separate legal entity — for the public transit services Bi-State delivers. Bi-State also operates the Gateway Arch Riverboats and manages the Gateway Arch transportation systems under separate contractual arrangements with the National Park Service, but transit operations represent the core statutory function.

The governing board consists of 10 members: 5 appointed by Missouri (through the Governor with Senate confirmation) and 5 appointed by Illinois (through the Governor). This equal representation structure is mandated by the compact and cannot be altered by either state acting alone. Actions require approval from representatives of both states, giving each state an effective veto on major policy decisions.

Scope of this page: This page addresses Bi-State Development's role as a transportation authority for the St. Louis bi-state metro area. It does not address Bi-State's non-transit commercial operations in depth, nor does it cover municipal transit programs operated independently by local jurisdictions outside the Bi-State district. For governance of adjacent planning bodies, see the East-West Gateway Council reference.

How it works

Bi-State Development funds Metro Transit operations through a combination of farebox revenue, federal grants, and dedicated local tax levies. The primary local funding mechanism in Missouri is a sales tax authorized under Missouri Revised Statutes Chapter 238, which permits transportation development districts to levy a sales tax subject to voter approval. On the Illinois side, funding flows through a combination of state appropriations and Regional Transportation Authority (RTA) allocations administered under the Illinois Regional Transportation Authority Act (70 ILCS 3615).

Metro Transit's fixed-route network breaks into three operational categories:

  1. MetroLink — The light rail system operating approximately 46 miles of track with 38 stations, connecting Lambert-St. Louis International Airport in Missouri to the Shiloh-Scott station in St. Clair County, Illinois (Metro Transit system map, Bi-State Development).
  2. MetroBus — Fixed-route bus service operating across the bi-state district, covering routes within St. Louis City, portions of St. Louis County, and the Metro East Illinois counties.
  3. Metro Call-A-Ride — Paratransit service mandated under the Americans with Disabilities Act of 1990 (42 U.S.C. § 12143), providing demand-responsive rides for eligible passengers who cannot use fixed-route service.

Federal capital and operating grants flow primarily through the Federal Transit Administration (FTA) under Title 49 of the U.S. Code, and Bi-State must comply with FTA grant conditions including Title VI civil rights requirements and drug and alcohol testing programs.

Common scenarios

Transit governance in the St. Louis region generates recurring points of confusion that arise from the layered nature of the compact structure.

Route and service decisions — MetroBus route changes, frequency adjustments, and service eliminations are decided by the Bi-State board. Individual municipalities in St. Louis County cannot unilaterally require or prevent route changes; they may advocate through the board process but hold no direct authority over service levels.

Missouri vs. Illinois funding differences — A rider boarding MetroLink at a Missouri station and alighting at an Illinois station crosses a state line, but the trip is governed by a single fare structure set by the Bi-State board. The two states' differing public finance laws affect how tax revenues are raised to support the system on each side, not how fares or services operate end-to-end.

Relationship to East-West Gateway — East-West Gateway Council of Governments (East-West Gateway) serves as the federally designated metropolitan planning organization (MPO) for the St. Louis region. East-West Gateway controls the distribution of federal transportation planning funds and develops the region's long-range transportation plan. Bi-State/Metro Transit is a project sponsor within that planning framework, not the same entity. A transit capital project must appear in East-West Gateway's Transportation Improvement Program (TIP) to be eligible for federal funding.

Paratransit eligibility disputes — Call-A-Ride eligibility is governed by ADA functional standards, not by Bi-State policy alone. The FTA's ADA regulations at 49 C.F.R. Part 37 set the floor for eligibility determinations, and Bi-State's eligibility process must conform to those federal requirements.

Decision boundaries

Understanding which body holds authority over a given decision prevents misrouting of advocacy, complaints, and funding requests.

Bi-State Development decides:
- Metro Transit fare structures and fare policy
- Service levels, route configurations, and schedules on MetroLink and MetroBus
- Capital project priorities submitted to the FTA
- Labor contracts with unionized transit employees
- Operating rules and passenger conduct codes

Bi-State Development does not decide:
- Highway projects and road infrastructure — those fall under the Missouri Department of Transportation (MoDOT) or the Illinois Department of Transportation (IDOT)
- Regional transportation planning priorities — governed by East-West Gateway Council under 23 U.S.C. § 134
- Land use and zoning around transit stations — those decisions rest with the municipality or county in which the station is located (for example, St. Louis City zoning is governed by the St. Louis Zoning Code framework)
- Public school transportation — not covered by Bi-State; see St. Louis Public Schools Governance

A comparison of Bi-State's authority versus a purely Missouri state agency illustrates a structural difference: a Missouri-only agency is subject to Missouri executive oversight and can be restructured by Missouri statute alone. Bi-State, as a compact agency, requires concurrent action by both state legislatures and, for any change to the compact itself, approval from the U.S. Congress. This makes Bi-State structurally more stable against unilateral state action but also slower to reform when structural changes are warranted.

The Illinois counties within the Bi-State district — primarily St. Clair County and Madison County — are subject to Illinois law for all non-transit matters. Transit riders in those counties using MetroLink or MetroBus are served under the interstate compact, but employment law, property tax, and municipal regulation in those areas fall under Illinois jurisdiction and are outside the scope of Missouri-based governance references on this site.
