25 CFR 170.128 - Are housing access roads and housing streets eligible for IRR Program funding?
Yes. IRR housing access roads and housing streets on public rights-of-way are eligible for construction, reconstruction, and rehabilitation funding under the IRR Program. Tribes, following the transportation planning process as required in subpart D, may include housing access roads and housing street projects on the Tribal Transportation Improvement Program (TTIP). IRR Program funds are available after the projects are listed on the FHWA-approved IRRTIP.
