Traffic Control Update

  • The Montana Department of Transportation (MDT) and Diamond J Construction plan to begin paving this week, weather and other unforeseen factors permitting. A pilot car will direct single-lane traffic through the work zone. Expect 10 to 15-minute delays. This work is expected to last approximately two weeks.
  • The 7th Street with Washington Street intersection has reopened to traffic.
  • The River Street intersection is temporarily closed to traffic as underground utility and concrete work continue northward.

Project Overview

The Montana Department of Transportation (MDT) has partnered with Diamond J Construction to make improvements along Montana Highway 59 (MT 59), in Miles City. Construction will begin at the intersection of MT 59 with Main Street and will continue north for approximately two miles, ending just past Secondary Highway 489 (Kinsey Road).

The purpose of this project is to rehabilitate the existing roadway, enhance safety features, and reduce maintenance costs. In addition to the roadway improvements, the City of Miles City will be updating the water main, sewer line, and storm drain on the segment of roadway south of the Yellowstone River. This work will be done in cooperation with MDT’s road construction project to minimize impacts to the public.

Planned improvements include:

  • Reconstruction of the roadway (south of the Yellowstone River bridge).
  • Widening the shoulders and new plant mix surfacing (north of the bridge).
  • New rumble strips (north of the bridge).
  • Replacement of all non-compliant Americans with Disabilities Act (ADA) ramps.
  • Upgrades to existing sidewalks and ADA curb ramps.
  • Upgraded pavement markings, signage, and guardrail.
  • City utility improvements to the water main, sewer line, and stormwater management system (south of the bridge).
