Staff Analysis

Senate Bill 5 proposes a transformative restructuring of public transportation governance and planning in the northeastern Illinois region. Through the creation of the Metropolitan Mobility Authority (MMA), the legislation consolidates several major transit agencies into a single, unified authority and introduces a new framework for transit-supportive development aimed at promoting equitable and accessible land use around high-quality transit services.

1. Creation of the Metropolitan Mobility Authority

SB 5 enacts the Metropolitan Mobility Authority Act, which consolidates the Chicago Transit Authority (CTA), the Regional Transportation Authority (RTA), and the RTA’s Service Boards—Pace (Suburban Bus) and Metra (Commuter Rail)—into the new Metropolitan Mobility Authority. As part of this overhaul:

The Metropolitan Transit Authority Act and the Regional Transportation Authority Act are repealed.

The former agencies are replaced by three operating divisions under the new MMA:

Chicago Transit Operating Division

Commuter Rail Operating Division

Suburban Bus Operating Division

This consolidation aims to eliminate overlapping administrative structures and enable more integrated regional transit planning, policy, and service delivery.

2. Operational Framework and Governance

The bill reinserts and reorganizes relevant provisions from the repealed Acts into the new statutory structure, establishing guidelines for the governance, funding, and oversight of the MMA. It also aligns various existing statutes with the new governance model by making conforming amendments to numerous Illinois laws, codes, and administrative regulations.

Additionally, SB 5 adds a provision to the Toll Highway Act, granting the Chair of the MMA a nonvoting seat on the Illinois State Toll Highway Authority, further linking highway and transit planning across the region.

3. Equitable Transit-Supportive Development Act

In parallel with the governance reforms, SB 5 creates the Equitable Transit-Supportive Development Act, which aims to promote land use practices that support increased transit ridership and equitable community development. Key components include:

The establishment of an Office of Equitable Transit-Oriented Development and a Transit-Supportive Development Fund.

The provision of targeted funding to municipalities that:

Adopt a transit support overlay district, or

Implement zoning and land use reforms that meet or exceed the benefits of such districts.

Oversight responsibilities for setting development standards, determining eligibility, and producing evaluation reports.

This initiative recognizes the importance of aligning transit investments with housing, jobs, and sustainable land use in order to create more vibrant, accessible communities.

4. Creation of the Office of Public Transportation Support

SB 5 also amends the Department of Transportation Law to require the Illinois Department of Transportation (IDOT) to establish an Office of Public Transportation Support. The Office’s mission is to optimize transit vehicle operations and service delivery on roadways under IDOT’s jurisdiction within the MMA’s service region. Its responsibilities include coordination with the MMA to enhance service efficiency, reliability, and intermodal connectivity.

5. Effective Date and Implementation

Some provisions of the bill are effective immediately, setting the stage for a staged implementation process. The complete transition to the Metropolitan Mobility Authority would require substantial administrative, legal, and operational work, likely over a multiyear timeline.

Summary

SB 5 is one of the most ambitious transit reform proposals in recent Illinois legislative history. It seeks to modernize and unify the region’s fragmented transit governance under a single agency—the Metropolitan Mobility Authority—while also laying the groundwork for equitable, transit-oriented development across the region. By aligning governance, planning, land use, and service optimization, the bill represents a bold shift toward a more integrated, rider-focused, and sustainable transportation system.
