December 8, 2022
The Montana Department of Transportation (MDT) and Riverside Contracting will pause construction tomorrow on the Armington Junction project.
Riverside Contracting crews will return in the spring to lay the second "lift" or layer of asphalt on the roadway north of the new Belt Creek bridge and seal and cover (chip seal) the entire project. Chip sealing is used to extend the life of the roadway, as well as keep water from penetrating the pavement and improve the driving surface.
MDT Great Falls District Administrator Jim Wingerter stated, "We are grateful to the public for their patience on this project. I appreciate the Riverside Contracting crews who have been working nights and weekends to get the project paved before winter."
Russ Gaub, Engineering Project Manager at Riverside Contracting, stated, "We appreciate the public’s understanding this fall. The project was delayed by inclement weather and our choice to help our neighbors along the Yellowstone River with flood mitigation.” Gaub added, “We look forward to finishing the project in the spring."
Don’t Crowd the Plow!
While driving, be on the lookout for snowplows and give operators room to work. Many plows are hit by private vehicles each winter, with the potential to cause harm to all parties involved. The plow truck and operator are taken out of service immediately following an incident.
Drive safely this winter and keep these tips in mind:
- Don’t pass a plow when the TowPlow is deployed. The operator will periodically rotate the TowPlow back in line with the truck to allow vehicles to pass.
- Be aware that, where there is one plow working, others may be nearby. The snow cloud created by one plow may obscure presence of additional plows in adjacent lanes.
- When approaching a snowplow from the rear, reduce speed immediately.
- When approaching an oncoming plow, don’t crowd the centerline.
- Be patient. Plow operators know where they can pull over to let vehicles pass, but remember, the road in front of the plow is likely not as clear as the road behind it.
MDT has tools to help plan for conditions so you can reach your destination safely. Find more plow safety information and winter driving tips on MDT's Winter Driving page.

MDT and Riverside Contracting thank you for your patience as construction continues at Armington Junction. The project team received several comments over the weekend about the conditions of the detour through the project. Conditions deteriorated rapidly this past weekend due to the construction site receiving about three inches of rain, but Riverside Construction crew members have worked hard to improve the driving surface, and it is in much better shape. Along with weather, heavy traffic makes the unpaved surfaces decline rapidly. The site is bladed daily and receives dust control frequently. Traffic at the project continues to drive on the subgrade of the new road as it is being built. As the crews make progress moving north, additional layers will make the travel surface much smoother. The construction site is approximately three miles, and the traveling public should be prepared for slow speeds as pilot cars lead traffic through the site, allowing work to continue safely. At night, lanes are created using reflective cones and barrels.

Armington Junction Construction site, 10/4/22
Crews are starting to pour concrete for the new curbs of the roundabout and will begin paving the new roadway as soon as they can. Work also continues on the new bridge over Belt Creek. Concrete was poured last week for the last section of the bridge deck. This week, crews will be working on the concrete barrier rail for the bridge.

Building Connections to Bring Montana Together – Good Roads Day is June 21, 2022
There are over 73,000* miles of roads open to public travel in our state (including nearly 12,923 miles of MDT routes) that accommodate nearly 13 billion annual vehicle miles traveled (AVMT). Simply put, roads and roadways (including bridges) keep our great state connected and moving forward! The third Tuesday in June marks Good Roads Day – designated by the Montana Legislature in 1947, whereby the people of the state are asked to contribute toward the improvement and safety of public highways (MCA 60-1-104). For MDT, building “good roads” takes time and means a continuous planning process that is underway long before ground is ever broken on a project. It can take eight years to complete a road project, but long-range planning starts anywhere from 1-20 years prior to the project start date. As transportation needs outpace revenue 3 to 1, MDT focuses on safety and preserving and maintaining transportation infrastructure as top priorities; in other words, keeping Montana’s good roads in good order. Join MDT in celebrating Good Roads Day on June 21, 2022, and share what #GoodRoads mean to you!

The Montana Department of Transportation (MDT), in conjunction with Riverside Contracting have nearly finished building half of the new bridge over Belt Creek on US 87 just north of Armington Junction. This work has had minimal impact on traffic because crews built a temporary structure called a work bridge allowing work without disrupting travelers.
Recently, crews poured concrete for the new bridge deck. While they wait for the concrete to cure, and gain the necessary strength to bear traffic, crews are building the bridge barrier rail and removing the work bridge. Next, crews will start building approaches to the new bridge, where traffic will be diverted as work begins demolishing the old bridge and building the second half of the new bridge.
Currently, crews are building the approaches to the new bridge. On approximately April 18, after the approaches are built, the traveling public should be prepared for traffic control and minor delays as they begin to detour over the new bridge. Two-way traffic will remain, but folks may experience minor delays, pilot cars, and signal lights controlling traffic.

The Sletten crews are continuing work this week on the Bridge over Belt Creek. Work will include continuing the installation of piles, which entails driving long, narrow steel columns into the ground to create a deep foundation for the bridge. When the piles are driven into the ground the friction makes them stronger. Essentially, the resistance between the pile and the surrounding earth creates an extremely strong foundation for further construction.
Crews will also be installing temporary shoring (driving sheet piling into the ground next to the roadway to hold back the roadway embankment) on bent 3. Bents are the structures that provide vertical support for the bridge.
Work should continue without major disruptions to traffic, but the traveling public may see temporary single-lane closures with a traffic light to control traffic as needed as the Sletten crews move their equipment around the work site.

Bridge work continues this week with the crews from Sletten Construction. They will be working on one of the bridge bents, which is the structure that provides vertical support for the bridge. Specifically, they will be doing grading work to support bent 1, which means ensuring a level base for the structure. Then they will begin piling work. This entails driving long, narrow steel columns into the ground to create a deep foundation for the bridge.

This week the crew will be working around the bridge, building up the embankments on the ends of the bridge to support the end bents which are the structures that will support each end of the bridge span. This will entail minimal impacts to the public, but there may be temporary single lane restrictions and flaggers and signals.
Watch for the Cone Zone
As you travel through construction sites, please remember the three S's of work zone safety: speed, space, and stress.
1. Manage Your Speed
Slow down when approaching all work zones. You will be in the work zone quicker than you think.
Follow posted speed limits, especially within construction zones, and try to maintain a consistent speed with the traffic flow. And adjust your speed for weather conditions.
Don't resume normal speed until you see roadway signs indicating it's safe to do so.
2. Manage Your Space
Leave room. Leave adequate braking room between your vehicle and the one ahead of you. Count out at least two seconds from the time the car ahead of you passes an object and the time your own car passes that object. Also, keep a safe distance between your vehicle and traffic barriers, trucks, construction equipment and workers.
Don't pass on the shoulder. Don't drive across the median. This creates a very dangerous situation for you, construction workers and other motorists.
Give yourself an out. When stopped in traffic, leave a safety zone between you and the vehicle in front of you. A good rule of thumb is that when stopped in traffic you should be able to see the bottom of the tires of the vehicle in front of you.
Don't try to force tailgaters to back off by slamming on your brakes. At night, lightly tap your brake pedal to illuminate your brake lights to warn tailgaters they are too close. During the day, turn your headlights on and off several times to illuminate your tail lights.
3. Manage Your Stress
Keep Your Cool. Calm down. Don't rush. Remember, the temporary inconvenience of a construction zone will soon pay off with greatly improved roads.
Pay Attention. Avoid cell phone or radio distractions, as well as those of other stopped cars or construction.
Expect Delays. Use the Traveler Information Map to learn about construction; leave a bit earlier; or try an alternate route.

Construction starts today on the Armington Junction Belt North and South project. This year, the project will focus on the bridge and culvert structures, including off-site building of the new bridge over the winter. The construction to widen the roadways and install the roundabout at Armington Junction is planned to occur in 2022. Initial operations will include removing trees and shrubs in order to allow for the bridge and culvert work to proceed. This will entail minimal impacts to the public, but there may be temporary single lane restrictions and pilot cars.
