Project
HELP !!!!!!
International border bridge located over the Rainy River on the Minnesota Trunk Highway 72 and Ontario Provincial Highway 11
This route provides access to and from Baudette, Minnesota and Rainy River, Ontario, a connection between the United States and Canada as well as a full-service, 24-hour Port of Entry
Operated as a toll bridge until 1988
Background
Project Location
This project was initiated as a result of the Chapter 152 funding intended to address structural issues
This bridge was constructed in 1959 with a total length of 1,285 feet, a 2-lane roadway with a width of 24 feet and an open grate steel deck
The bridge is classified as fracture critical (non redundant) and has a sufficiency rating of 48.8 out of 100
Project Need
6-Foot Wooden Walkway
Open Grate Steel Deck
There is substantial section loss (up to 50%) on some members
The steel truss exhibits pack rust and free edge distortion on many gusset plate connections
The knee bracing on the overhead truss members were removed after being impacted a number of times
Active corrosion on the structural members will continue to reduce the structural capacity of this bridge over time
Project Need
Stringer and Deck Corrosion
Stringer/Floor Beam Connections
Floor Beam Section Loss and Corrosion
Distortion at Truss Connections
Bridge can support normal weight loads, but not ‘permitted’ overweight loads (Type B and C) and over-dimensional loads (over 14.7’ high)
Both high and wide loads have impacted the vertical and overhead truss members
Microbial induced corrosion (corrosion due to water-borne bacteria) is evident on the steel caissons
Project Need
Bridge Hit
Bridge Railing Condition
The project is currently scheduled for a November letting in 2017, but could potentially be let sometime between 2016 and June of 2018
Ontario has finished their Cultural Heritage Evaluation process; MnDOT will start its historical process soon
Steps from this point are dependent of the results of the historical process

Other Anticipated Stakeholders
MTO has determined that this bridge does not qualify for the Ontario Heritage Bridge List, and thus does not consider rehabilitation as a viable option
Discussions have taken place considering each partner build their half and meet at the center of the river
Recent experience has shown agencies from Canada, U.S., Minnesota and Ontario will not recognize authority being limited to the international border
Expected Challenges
Labor and contracting laws differ in each country
Developing an agreement to transfer dollars from one government entity to the other could prove challenging
Geometric standards differ slightly for the transportation agencies
Expected Challenges
Materials requirements, such as concrete and steel, need to be kept as uniform as possible so the bridge reacts consistently
Needs of the communities, businesses and border facilities will need to be addressed
Other ???
Expected Challenges
Cooperative Agreement between Minnesota and Ontario is still in development
Will need to address/resolve many of the challenges identified
Ontario’s comments on the draft agreement reflect their desire to have each partner build ½ of the bridge
Cooperative Agreement
