The TAP replaces the funding from pre-MAP-21 programs including Transportation Enhancements, Recreational Trails, Safe Routes to School, and Scenic Byways, wrapping them into a single funding source. The FAST Act has continued authorization of this funding for transportation alternatives projects.

Federal TAP funds are provided through the FHWA. Projects using TAP funds are eligible for reimbursement of up to 80% of allowable costs. The LPA is required to match the project with a minimum of 20%. Refer to EPG 136.3.9 Local Match Guidelines for local match guidelines for transportation alternatives projects.

Compensation for expenditures will be authorized on a cost reimbursement basis. Expenditures incurred prior to receiving a formal notice to proceed will not be eligible for reimbursement.

MoDOT distributes TAP funds outside TMA boundaries every two years (even years) through a competitive selection process. The FAST Act provides for TMAs to receive a separate allocation of TAP funding through Surface Transportation Block Grants (STBG). TMAs develop their own TAP guide and selection criteria while still adhering to federal rules outlined in the FAST Act.
