I
nternational
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



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



There
is substantial section loss (up to 50%) on
some members


T
he
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



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



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

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



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




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 ???


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
