The Granite City Crossing was built on the site of the former
DeSoto Bridge in Saint Cloud, Minnesota. This key regional river crossing
fell victim to the I-35W Bridge collapse since it was the same design as
the former I-35W Bridge, and it had similar structural problems. These
issues resulted in the DeSoto Bridge being closed by MN-DOT shortly after
the I-35W disaster. It was removed in the fall of 2008. The replacement
bridge was put on a fast track in order that it be built and opened within
a year of the old bridge being demolished.
The new bridge features two piers in the Mississippi River, and one
smaller pier on the east end of the structure. This results in 3
over-river steel girder spans, and one smaller pre-stressed concrete girder
span on the east end of the bridge over Riverside Avenue. While the deck
is about the same height above the water as the DeSoto Bridge, the
clearance under the new bridge is much higher given that the new
bridge does not have the metal trusswork under the deck that existed on
the DeSoto Bridge. Like the DeSoto Bridge, the new structure is
just shy of 900 feet long. It is, however, significantly wider to
allow for wider sidewalks, wider traffic lanes, and several bump-outs for
observation areas.
The new bridge features granite, a common construction material native to the
Saint Cloud area. In fact, the new bridge has been named the Granite City
Crossing. While it is sleek looking and is a highly functional modern
structure, losing the amazing DeSoto Bridge is a very high price to pay from
a historical standpoint.
A bridge dedication ceremony was held on Monday, October 26, 2009 to celebrate
the opening of the new Granite City Crossing. People were allowed to walk the
bridge after the dedication. The bridge opened to traffic on Thursday,
October 29. The bridge was finished a bit ahead of schedule, for which the
contractor has earned a bonus.
The photo above is looking northeast along the downriver face of the Granite
City Crossing from the plaza at the south corner of the structure. The photo
below is looking southwest along the downriver face of the bridge from the
east corner of the structure. Downtown Saint Cloud is visible in the
background.
These two photos are views of the main river spans taken in the spring of
2010. The photo above is looking northeast, while the photo below is looking
southwest. Both views are of the downriver face of the structure. Note
the open spots in the ice paralleling the bridge. This is due to road
salt that was mixed in with snow that was thrown over the side of the bridge
when it was plowed over the winter. This is exactly the type of pollution
that should never be allowed to enter the river.
The photo above is a close view of the expansion joint at the southwest
end of the bridge. The photo below is a view of one of the observation
bump-outs. Both photos show the granite and railings on the upriver side
of the bridge.
The photo above is a view of the southwest end of the bridge deck nearest
to downtown Saint Cloud. The photo below is a view looking northeast down
the sidewalk on the downriver side of the bridge deck from mid-span.
The photo above is looking northeast towards the end of the bridge deck
as seen from the sidewalk on the downriver side of the structure. The
photo below is a close view of a banner that is hanging from the light
poles. This banner is commemorating Saint Cloud being selected as the
most livable city in the world in 2007, and its top 10 finish in 2009.
These two photos are views of the bridge abutments. The photo above is the
Stearns County side of the river as seen from the plaza near the south corner
of the structure. The photo above is the Benton County side of the river
near the east corner of the bridge. The abutments, railings, and one
bridge pier are faced with granite native to the Saint Cloud area.
The photo above is a view looking upriver from the plaza and regional trail
that runs under the southeast end of the bridge. The Veterans Bridge and
BNSF railroad bridge are visible a few blocks to the north of this location.
The photo below is looking downriver from the same spot. The east bank of
the river is largely residential.
The photo above is looking northeast along the center line of the underside
of the bridge. A water main is hung under the bridge deck. The photo below
is a close view of the water main as it enters the bridge abutment. Note
that the pipe is hung on bearings that allows the bridge to expand and
contract without moving the pipe.
The photo above is a view of the structure at the southeast bridge abutment.
The steel is painted brown, but a gray rust inhibitor has been painted on the
steel at the end of the bridge near the expansion joint. This is to protect
the steel from any salt runoff that seeps through that joint. The photo below
is a close view of a gusset plate under the bridge. The gusset plate is
welded to the horizontal beam, but it is bolted to the girder and crossmember.
The photo above is an overview of the construction project in March, 2009,
as seen from the construction site on the east side of the project. The
photo below is close view of the progress on the eastern of the two main
bridge piers. Workers have installed a cofferdam using sheet pile, then
drove pilings into the riverbed. From there, footings were installed,
and now rebar cages are being assembled to form the bridge pier.
These two photos are progress as of March, 2009, on the east bridge abutment
(above) and a pier that will support the east end of the main river spans as
well as one end of a smaller span on the east end of the bridge that will
cross Riverside Avenue (below).
These two photos show construction work on the west end of the new MN-23
bridge. The photo above is a view from the project site on the east
side of the river, while the photo below is a view from a riverside park
located just downstream from the project.
These two photos show construction work on the east end of the new MN-23
bridge. The photo above is a view from the project site on the west side
of the river, while the photo below is a view from a site just downstream
of the river crossing.
These two photos show construction in June, 2009, on the main river spans
(above) and the approach span on the north end of the structure (below).
These two photos are more views from June, 2009. The photo above is the
main river channel span as seen from the construction site on the east
side of the project. The photo below is a close view of the eastern of
the two main river span piers.
