Transportation Development Act Article 3

NOTE: As a result of COVID-19, reimbursement requests should be submitted electronically to Do not send hard copy requests.

Transportation Development Act Article 3, or TDA 3, provides funding annually for bicycle and pedestrian projects.

Two percent of TDA funds collected in the county is used for TDA 3. MTC allows each county to determine how to use funds in their county. Some counties competitively select projects while other counties distribute the funds to jurisdictions based on population.


MTC Resolution 4108 sets forth MTC's policies and procedures for TDA 3 funds. All projects must be reviewed by the City or County Bicycle Advisory Committee. For more information, review the Guidance on Project Review by Countywide BAC.

Allocations and Reimbursements

Each county coordinates a consolidated annual request for projects to be funded in the county. Learn more in the TDA Article 3 Application.

MTC reviews applications and allocated funds to eligible projects. Project sponsors request reimbursement. Resolution 4108 explains how to seek reimbursement.
