HELENA, Mont. — The Montana Department of Transportation (MDT) would like to announce and invite the public to comment on a proposal to resurface about 1 mile of Prospect Avenue, in Helena. The project begins at the Prospect and Montana Avenue intersection, and extends east, ending at the Interstate 15 (I-15) off-ramp at the Capitol Interchange.
Proposed work includes milling the existing pavement, replacing it with new asphalt, and applying a seal and cover (chip seal). New pedestrian crossing flashers will be added at Sanders Street and Oakes Street. Sidewalk corner ramps will be upgraded to meet current Americans with Disabilities Act (ADA) standards. Additional work includes new signage and pavement markings. The purpose of the project is to extend the service life of the roadway and to improve pedestrian crossing facilities.
Construction is tentatively planned for 2026 depending on completion of design and availability of funds. Right-of-way acquisition or temporary construction permits will likely be required for this project. Relocation of utilities may also be necessary. MDT staff will contact affected landowners prior to survey work. Landowners may be contacted again prior to construction regarding temporary permits.
Partnering with the community is an important part of properly planning for future projects. MDT welcomes the public to provide ideas and comments on the proposed project. Comments may be submitted online at mdt.mt.gov/contact/comment-form.aspx or in writing to Montana Department of Transportation, Great Falls office, PO Box 1359, Great Falls, MT 59403-1359. Please note that comments are for project UPN 10312000.
The public is encouraged to contact Great Falls District Preconstruction Engineer Jim Combs at 406-454-5900 or Project Design Engineer RJ Snyder at 406-459-5294 with questions or comments about the project.
