Summary of HB 3514 (2026) — Missouri

Purpose and intent

Establishes a requirement that the Missouri Department of Transportation (MoDOT) obtain approval from the governing body of the affected local government (county, city, town, or village) before constructing a roundabout on certain roadways.

Applies to roundabouts planned on federal highways, state numbered highways, or state routes located within a local jurisdiction.

Key provisions and changes

New section added to Chapter 229 (section 229.224) with the following core requirements:

MoDOT must seek consent from the governing body of the relevant local government prior to constructing a roundabout on any federal highway, or numbered state highway or state route within that county, city, town, or village.
The local governing body has 30 days to report its decision to MoDOT after MoDOT requests consent.
Definition of “roundabout”: a road junction where traffic moves in one direction around a central island to reach one of the roads converging at the junction.

Who is affected

MoDOT procedures for roundabout projects on federal or state highways will involve an additional step of local consent.

Local governments (counties, cities, towns, or villages) would gain a formal decision-making role in approving or denying proposed roundabout projects affecting their jurisdiction.

Residents and travelers could experience potential delays or negotiations tied to local approval timing, depending on how consent decisions align with project timelines.

Procedural and timeline considerations

Consent process: MoDOT must obtain consent from the local governing body before construction can proceed on the specified roadways.

Timeline: Local governments have a 30-day window to respond with their decision after a consent request is made.

The bill uses a clear, time-bound reporting requirement intended to keep project planning moving while ensuring local input.

Additional notes

The measure is similar in concept to HB 1484 (2025), indicating a continuing legislative interest in ensuring local authority over certain changes to roundabout infrastructure.

Current action history indicates the bill was referred to Emerging Issues (H) as of May 15, 2026, after being introduced and read in prior sessions.

Practical impact

If enacted, MoDOT would need to coordinate with local governing bodies early in the planning stage for roundabouts on federal/state roadways within local jurisdictions.

Local governments would have a formal 30-day period to consider and communicate their approval or disapproval, potentially affecting project scheduling and approvals.

The bill does not specify criteria for approval or denial beyond the consent mechanism; local decisions would presumably be based on local considerations such as traffic flow, neighborhood impacts, and budget priorities.
