U.S. 83/Broadway Bridge Replacement

Project Description

The North Dakota Department of Transportation (NDDOT), in cooperation with the Federal Highway Administration and the city of Minot, is replacing the existing U.S. 83 Broadway Bridges in the heart of Minot. This work started in March 2017 and is anticipated to be finished by the end of 2018.

This project is important to residents in Minot and travelers in north central North Dakota, as the five-lane urban roadway carries approximately 30,000 vehicles per day. These bridges remain safe for drivers, and are still being used to convey traffic during construction. The demolition of the old bridges and construction of the new bridges is part of the NDDOT’s proactive plans to replace the bridges.

During construction seasons the traffic will be reduced to head-to-head flow on just one side of the two bridges, allowing the public to continue using this route while one portion of the bridge is under construction. During the winter of 2017-2018 both bridges will be open to traffic: the new bridge constructed in 2017 (the east bridge) will be open to two northbound lanes, and the old bridge (the west bridge) will be open to two southbound lanes. Also during the winter of 2017-2018 and during construction in 2018 the Central Avenue intersection will be open to “right in” and “right out” access; the Central Avenue intersection is closed during construction in 2017.

Timeline of Project

  • Project Awarded - December 2016
  • Construction Start - Week of March 20, 2017
  • Estimated Construction end for 2017 - Late October/Early November
  • Estimated Construction for 2018 - March to October/November

Public Involvement

The public is encouraged to be involved in the current and on-going process of helping to develop the look and feel of the new U.S. 83 Broadway Bridge. An anticipated early June public meeting will be a prime opportunity for members of the general public to make their opinions heard. In the meantime, designers and engineers will be working with city officials, local businesses and community leaders to get an early start on potential design concepts.

Frequently Asked Questions

Why is this project being done? Are the Broadway Bridges safe to travel on?

The bridges are safe. Some early signs of deterioration were noticed during a recent inspection of the underbody of the bridge and this caused the NDDOT to upgrade the project from a previously planned deck replacement to a bridge replacement. As NDDOT looked at the cost to continue maintenance on the existing bridge, it was economically apparent to build a new bridge.

How long will the construction take? When will the bridges be back to normal driving?

It is anticipated that demolishing and reconstructing the two bridges will take two construction seasons, 2017 and 2018. During the winter of 2017-2018 the east bridge (under construction in 2017) is set to be open to northbound traffic. Both bridges and adjoining intersections will return to normal traffic patterns at the end of the entire project.

How is the impact to businesses in this area being minimized and are there any detour routes I should be taking?

At least one entrance is being maintained into the handful of businesses directly impacted by the bridge replacement project. This includes access to Bremer Bank, I. Keating Furniture, Wells Fargo Bank, and Sammy's Pizza. Appropriate localized routes are marked for access to adjoining roads currently not directly accessible off Broadway. No detour route is in place for the project as head-to-head traffic is being maintained on whatever side of the bridge is not currently under construction. The driving public is still encouraged to use US 83/Broadway in traveling through or into the heart of Minot. Downtown Minot remains open during this construction as well.

What changes or upgrades are being done with the new bridges?

This is a complete demolition of the old bridges and a construction of new bridges. The bridges will remain in nearly the same footprint as they have the last 50+ years. They will be slightly taller, by approximately 1.5 to 2 feet, due to railroad clearances needed below the driving surface of the bridge. There will be fewer piers/columns that make up the underside of the bridge, from 14 to 8. The north abutment of the bridges will tie into the flood protection plan being done for the north side of this portion of the Mouse River. A pedestrian walkway will be part of the east bridge.

How are the improvements going to make this area more pedestrian and public friendly?

The improved pedestrian walkway on the east bridge will be wider than the current version and have a overlook/bumpout at just over the Mouse River to encourage pedestrian activity. The wider walkway will also be more biker friendly. New decorative LED street lights are also being used on the bridges and are of a similar design to those going in place for the Downtown Infrastructure Improvements Project and those in place on North Broadway. This will provide for a connectivity over the river and the railroad tracks that cross in the center of Minot.

What is the estimated life span of the new bridges?

With proper care and upkeep it is anticipated that these bridges would last 50-75 years, much like the previous ones from the early 1960s and 1970s.

Who is paying for this project? How is the cost share being split?

The bulk of the funding is coming from Federal Highway Administration dollars, nearly 80%. The remaining cost is being shared by the State of North Dakota and the City of Minot.
