Project Updates

July 1-7, 2019

  • Last week concrete was poured for the new bridge structure and pouring for the bridge columns will continue into this week.
  • The asphalt has been removed from the eastbound interstate on and off ramps in advance of excavation and embankment activities this week. Work will continue on the reinforced soil slope this week as well.
  • The contractor plans to suspend construction operations by noon, Wednesday, July 3rd and return to work on Monday, July 8th. MDT hopes you have a safe 4th of July holiday.
  • Flaggers will continue to direct traffic on Haynes Avenue and the interstate ramps as needed for construction operations, Haynes Ave. traffic will continue to travel on the gravel detour, and the on and off ramps will also be gravel.
  • Remember to watch carefully for workers and equipment!

Previous Updates

June 24-30, 2019

  • MDT would like to thank the Miles City Community for your patience during pile driving operations. The support structures for the eastbound bridge are now complete and work continues on both the retaining wall and reinforced soil slope.
  • This week, pavement milling, and excavation work begins on the eastbound on/ off ramps. Travelers should prepare for flaggers to direct traffic on the ramps.
  • S. Haynes Ave traffic will continue traveling on the detoured gravel surface. Expect uneven driving surfaces, flaggers, and periods of one-lane traffic.
  • With so much happening at once, the Broadus Interchange is a busy construction zone. MDT appreciates your efforts to keep our construction crews safe by remaining "work zone alert." Remember to slow down and watch carefully for workers and equipment at all times.

June 17-23, 2019

  • Pile driving operations will resume this week, so the public is asked to prepare for daytime noise disturbances and ground vibrations.
  • Traffic will be shifted to the far east side of S. Haynes Ave. to accommodate the work; however, two-lane traffic will continue throughout the week.
  • The traveling public should expect flaggers and gravel surfaces. Remember to stay "Work Zone Alert," slow down and watch for workers and equipment.

June 10-16, 2019

  • MDT would like to thank community members for their patience throughout this process. On the interchange, construction of the MSE retaining walls was last week’s focus, and the retaining walls will be the main operation this week as well.
  • There will be minimal traffic impacts with this operation. Remember to slow down and watch carefully for workers and equipment in work zones.

June 2-9, 2019

  • MDT appreciates the community's patience during pile driving operations. We know things were loud for a bit. Bridge supports on the east and west end of the project are now complete.
  • This week, Oftedal will begin construction of two separate retaining walls adjacent to S. Haynes Ave.
  • Traffic disruptions during this phase of the project are expected to be minimal; however, drivers are asked to remain “Work Zone Alert”. Remember to slow down and watch carefully for workers and equipment.
  • Other Traffic Impacts:
    Bridge deck upgrades and guardrail replacement are underway on the MT-59, Yellowstone River Bridge north of Miles City.
  • Single-lane closures and 24-hour traffic control are in place, as is a 12-ft width restriction. Planning extra travel time is recommended. For timely detour and delay information click HERE.

May 20-29, 2019

  • Broadus Interchange construction will generate substantial noise and minor traffic impacts this week as crews continue pile driving operations for the eastbound bridge. Members of the public are asked to prepare for loud hammering noises and ground vibrations between the hours of 7:00 am-7:00 pm.
  • S. Haynes Ave. will remain open to two-way traffic throughout pile driving operations. Momentary delays may be necessary while crews move piling into place.
  • Pile driving is the first step in building a foundation for the new bridge. The operation involves hammering long metal columns deep into the ground using a diesel-powered hammer or other specialized equipment. It's an important technique for structures that must bear a lot of weigh such as bridges.
  • This week Oftedal Construction will also begin work on a reinforced soil slope east of bridge construction.
  • Please remember to slow down and follow all posted signs in construction zones. Workers are counting on you to make it home safely.

May 13-19, 2019

  • Broadus Interchange construction will generate substantial noise and minor traffic impacts this week as crews complete work on the eastbound retaining wall and begin installing bridge supports.
  • Drivers should expect reduced speeds and single-lane, one-way traffic on S. Haynes with flaggers present to direct traffic.
  • This week Oftedal construction will begin driving pile for the foundation of a new eastbound bridge spanning S. Haynes Ave.
  • Pile driving involves hammering long metal columns deep into the ground using a diesel-powered hammer or other specialized equipment. It’s an important technique for structures that must bear a lot of weight such as bridges, albeit one that creates a lot of noise. Members of the public are asked to prepare for substantial noise impacts and ground vibrations between the hours of 7:00 am – 7:00 pm.
  • Bucking Horse Sale Update
    The Montana Department of Transportation will pause major construction activity in Miles City May 16-19 to accommodate traffic from the annual Bucking Horse Sale. During this time, both South Haynes Ave and all four interchange ramps will be fully open to traffic. Eastbound lane closure and reduced speeds on I-94 will remain in effect.

May 6-12, 2019

  • Demolition of the Eastbound bridge structure is fully complete and Oftedal has moved on to construction of a retaining wall to be located at the base of the new bridge. Work last week focused on driving sheet piling to hold material for the wall in place during excavation. Sheet piling operations will continue this week along with excavation of the western portion of the new wall.
  • Members of the public are asked to prepare for daytime noise disturbances and to use extra caution when traveling through the work zone. Excavation activity will require frequent crossings of both S. Haynes Ave and the eastbound off-ramp. Remember to slow down and pay close attention to directions from flaggers. Single lane, two-way traffic will continue on I-94 throughout the summer.

April 7-14, 2019

  • Construction crews will begin demolition on the center portion of the eastbound interstate bridge Monday. To maintain the safety of workers and the traveling public all traffic will be diverted to the far east-side of S. Haynes Ave.
  • Drivers should expect single-lane traffic controlled by flaggers and rough roadway surfaces. Planning extra travel time is highly recommended.
  • Remember to remain “Work Zone Alert” by slowing down and paying careful attention to flaggers and signs!
