Bridges may be a lifeline for reconnecting Fort Berthold communities separated by the Garrison Dam and Lake Sakakawea after 65 years. Not only can they provide better access to vital services (jobs, education, health care), they will help reduce travel time, and provide safer travel alternatives across Fort Berthold.

Bridge Feasibility Study

What is a Bridge Feasibility Study?

A bridge feasibility study determines the feasibility, costs, risks, and benefits of building bridges such as the Charging Eagle Bay and/or Elbowoods Bridges over strategic points of Lake Sakakawea.

With the construction of the Garrison Dam and Lake Sakakawea in 1956, one-sixth of the Fort Berthold area was flooded (152,360 acres), and 70% of our road and bridge infrastructure was permanently lost. This displaced our families, destroyed sacred sites, ruined the best farmland, flooded valuable natural resources, destroyed the economy, and isolated communities that had previously been connected. The Charging Eagle Bay and Elbowoods bridges would help reconnect our communities, as well as create more viable corridors for trucking, recreation, and commercial travel. This would not only impact Fort Berthold, but the whole region!

In the early ’70’s, the Army Corps of Engineers conducted an environmental assessment (see document below) for the construction of the Charging Eagle Bay Bridge. At the time, the proposed bridge project was to span 4,500 feet across the Little Missouri River arm of Lake Sakakawea and connect State Highway 22 (near Mandaree) with State Highway 8 (near Twin Buttes). By conducting a feasibility study for the Charging Eagle Bay and Elbowoods bridge development, we can best understand the costs, benefits and investment required to reconnect our communities.


Why is Bridge Planning Important?

Access to Vital Services.

In conjunction with public transit, bridges are important for providing Fort Berthold residents access to essential services such as work, education, and health care. This also includes the ability for emergency first responders (ambulance, fire trucks or police) to reach remote and isolated areas quicker.

Connect Fort Berthold.

Not only would a bridge help reconnect Fort Berthold, but it would stimulate economic growth and connectivity across the region.

Reduce Travel Time.

The Charging Eagle Bay bridge would reduce the distance between Mandaree and Twin Buttes to only 22 miles (from 63 miles) and eliminate the need to drive off of Fort Berthold boundaries. The Elbowoods Bridge would reconnect the heart of Fort Berthold through East-West travel and reduce the Twin Buttes and White Shield journey to 20 miles (currently 103 miles that takes two hours in ideal traffic conditions).

Reconnect our communities.

By connecting isolated areas of Fort Berthold by bridge, there is greater opportunity to strengthen community relationships and improve our connectivity to the region.

Improve Emergency Response.

The proposed bridges would help reduce the distance and time needed for emergency responders and law enforcement officers to reach all segments of Fort Berthold. In emergency situations, time is crucial to protecting and saving lives.


In order for MHA Nation to ensure equitable health services, employment opportunities, and access to education with neighboring counties and states, it is essential to invest in a transportation infrastructure system that will help us achieve these goals.

Where do we come from?

Prior to the arrival of Europeans, the Three Affiliated Tribes had no need for bridges. We used the Missouri River for transportation, hunting, trading, as our main water source, and to cultivate our crops. Tribes from across the Great Plains traveled large distances to trade agricultural products and goods along the river with us. We occupied great distances along the Missouri, from Cannonball to Yellowstone (with other Tribes including the Crow), but our largest fortified villages prospered along the Heart River. In 1888, many communities moved away from Like-a-Fishhook village and settled 20 miles upriver in Elbowoods.1 Prior to the construction of the Garrison Dam, the old Elbowoods bridge  (constructed in 1934) crossed the Missouri at old Highway 8, near what is now Twin Buttes. In 1955, it was moved to a new location due to the construction of the Garrison Dam and subsequent creation of Lake Sakakawea. A new Four Bears Bridge was constructed in 2005.2 With the construction of the Garrison Dam and Lake Sakakawea in 1956, one-sixth of the Fort Berthold land area was flooded (152,360 acres including 94% of our best farmland), and our bridge (as well as 70% of our road infrastructure) was permanently lost. The flooding of our river displaced our families, destroyed sacred sites, ruined the best farmland, flooded valuable natural resources, destroyed the economy, and isolated communities that had previously been connected.

Where are we today?

Lake Sakakawea is the third largest man-made lake in the US (largest in North Dakota), and the only available crossing points to reach all segments are at Four Bears Bridge (west of New Town) or 20 miles east of Fort Berthold’s boundaries (Highway 83) near Coleharbor. Today, to get from White Shield to Twin Buttes requires commuters to drive 103 miles, yet a bridge crossing at Old Highway 8 would reduce this distance to 20 miles. Similarly, the drive from Mandaree to Twin Buttes would be reduced from 63 miles to 22 miles with a bridge. Currently, a study is being conducted to determine the costs, benefits, risks, and feasibility of constructing one or both of these bridges on Fort Berthold. For this feasibility study, FIGG (who was responsible for designing and managing the construction of Four Bears Bridge) partnered with CH2M, providing Fort Berthold nationally and internationally recognized experts in all project aspects. The FIGG/CH2M Alliance is working directly for MHA Nation within a co-project management structure that will allow them to dedicate their highest-level key personnel to most efficiently deliver the best quality study. To take this ambitious project from conception to completion, a suite of environmental, cultural, social, and engineering elements must be carefully analyzed. The study will follow a holistic approach that addresses tribal needs, economic and non-economic criteria, public involvement, environmental concerns, community connections, and traditional use in addition to bridge and roadway costs.

Where are we going?

Constructing one or more new bridges on Fort Berthold will require significant funding and investment, and the decision to build or not build will impact members of the Fort Berthold community for generations. This feasibility study will provide opportunities for public and stakeholder comment, analysis, data, and information needed to assist the public and leadership in making that decision. There will a series of public meetings in all of the segments starting in May, a presentation to Tribal council in August, and the feasibility study will be completed in September 2018. The series of public meetings will be designed to provide information, address areas of concern, risk, cost, necessity for further research, and create a basis for making future decisions. What do you think about the bridge feasibility study? How can we plan for our future in a way that aligns with our cultural, spiritual and environmental values while ensuring a strong economy, jobs, health and education for our communities? How can we engage the Tribal community (both off and on reservation), our youth, elders, spiritual leaders, veterans, businesses, schools, programs, neighbors as well as other stakeholders including State, Federal and County governments in a way that ensures a brighter future for our next generations? We want to hear from you!
