MDT district outlines 2025 interstate and local roadwork, pacing projects to limit overlap
Summary
Montana Department of Transportation representatives reviewed major 2025 projects including multiple interstate mill-and-overlay segments, bridge rehabilitation, district-wide signing and an inlaid striping program; MDT said schedules are staggered to avoid concurrent curb on interstate segments.
A Montana Department of Transportation district representative briefed the MPO technical committee on major 2025 construction projects and how MDT is sequencing work to reduce overlapping impacts.
The district representative summarized three large interstate projects — Rock Canyon, Bozeman Hill East and Bozeman East — that mainly involve mill-and-overlay work, bridge deck repairs and guardrail or barrier upgrades. The district will also implement a district signing project (D2/D3), an inlaid striping project and several NH- and CMAQ-funded local projects that include intersection and ADA upgrades.
"District manages a couple of pots of money," the MDT representative said, describing the annual Tentative Construction Plan process used to assign funding categories and program projects. MDT noted the inlaid (D2) striping layer overlaps some project limits, and staff said they are using change orders to sequence on-the-ground work for constructability.
MDT described local projects planned in the Bozeman area for 2025, including the North Nineteenth corridor (mill/overlay and intersection reconstruction at East Valley Center), the Jackrabbit–Amsterdam intersection improvements (part of a larger Belgrade program) and paired projects on North Seventh Avenue (intersection and surfacing work). The district said it staggered the notice-to-proceed and construction schedules on interstate segments so crews are not competing in the same corridor at the same time.
Committee members asked technical questions about materials and pavement depths. MDT said most intersection work will use plant‑mix asphalt rather than concrete and that inlaid striping is epoxy-based. The district noted that contractor and equipment availability, and bridge work complexity, are factors shaping schedules.
MDT also said 2025 is a relatively light local construction year compared with upcoming years and that additional large bridge and capital projects are expected in the next several years.
No committee action was required for the MDT briefing.
