The Cedar Avenue Bridge is a pair of twin spans consisting of large steel arch spans, flanked by long concrete girder causeways. The bridge spans the Minnesota River valley, including large wetland areas on each side of the main channel. These are certainly the most impressive bridge structures in the Twin Cities area. In fact, the Cedar Avenue Bridge is the longest bridge in Minnesota that is entirely within the state. The only other bridge in Minnesota that is in this league is the US-2 Bong Bridge in Duluth.

The Cedar Avenue Bridge uses a tied arch for the main spans. A tied arch has a large arch that connect to suspension cables. The suspension cables hold up the bridge deck. A tied arch has horizontal tie beams that connect to the two ends of each arch. The tie beams keep the arch from spreading out wider under the weight of the bridge deck. Since the arch will not get wider, the bridge piers only need to support the vertical weight of the bridge rather than having to push sideways against the arches. This allows the bridge to use much smaller and lighter piers under the arch spans.

The bridge is marked for three lanes of traffic, plus a wide shoulder on the outside of each span. Transit buses are allowed to use the bridge shoulders, so the bridge operates with four lanes on each span. This bridge often backs up northbound in the morning due to a number of slow exits north of the bridge. It is not unusual for morning traffic to back up all the way into Apple Valley. In addition, traffic from I-35E backs up on the loop to Cedar Avenue, and often back into the collector/distributor lanes. Now that the MN-100 ‘Ease The Squeeze’ project is complete, this is probably the single worst traffic issue in the twin cities metro area.

The photo above is looking northeast towards the parallel main span arches of the Cedar Avenue Bridge. The vantage point is the parking lot at the boat landing on the south side of the main river channel within Fort Snelling State Park. The photo below is looking northwest towards the main river spans. The vantage point is an overlook on the ramps leading to the bicycle bridge that is attached to the east side of the main river span.

The photo above is the view looking north between the two bridge spans from the Fort Snelling State Park parking lot on the south side of the main river channel. The photo below is the west face of the eastern span as seen from ground level. The bridge deck is about 50 feet above the ground. The bicycle bridge can be seen on the far side of this span.

These two photos are looking south across the main channel of the Minnesota River from a location between the two bridge spans. The photo above is the upriver west face of the northbound (eastern) span. The photo below is the downriver east face of the southbound (western) span. The island in the middle of the river can be reached by walking over the bicycle bridge that is attached to the side of the northbound bridge span.

These two photos are views from the two main channel tied arch spans as seen from the island on the north side of the main river channel. The view is looking southeast from two different angles. The pavement in the photo below is the roadway that carried traffic between the two segments of the old Cedar Avenue Bridge.

These two photos are views looking north under the concrete girder spans on the north side of the main river channel as the bridge crosses the island between the main river channel and backchannel marshes. The photo above is the northbound span, while the photo below is the southbound span. These photos were taken from the ramp leading to the bicycle bridge.

The photo above is looking north between the two concrete girder roadways. The bridge crosses the river at an angle to true north, so it needs to make a curve to line up with northbound Cedar Avenue on the Bloomington side of the river. The photo below is the first concrete girder spans located north of the main channel arch spans.

These two photos are views of the west face of concrete girder spans near the north end of the structure. The photo above is an overview photo, while the photo below is a close view of the spans located near the abutment at the north end of the bridge.

The photo above is one of the bridge piers that supports the concrete girder spans. The photo below is a close view of a joint where two sets of girders meet at a bridge pier. The gap between the girders allows the bridge to move slightly as it expands and contracts due to temperature changes.

The photo above is a view of the joint between the arch and the horizontal tie beam at the southeast corner of the northbound span. The chain link fence is part of the bicycle bridge railing. The photo below is a view of the main bridge span piers on the south side of the Minnesota River. Red and green lights hang under the bridge to mark the navigation channel.

The photo above is a close view of a bridge bearing on top of a main channel pier. Bearings allow the bridge to move slightly. This end is fixed in place, but it allows the joint to flex. The bearings on the north side of the channel are allowed to slide back and forth. This helps prevent the bridge from flexing and twisting as it undergoes temperature changes. The photo below is a close view of a pair of suspension cables as they attach to the arch.

These two photos are the first of a three photo set showing a typical river crossing heading northbound towards Bloomington. In the photo above, we are cresting the high point in the bridge just prior to entering the main river channel span. The photo below is a view from under the giant arch.

The photo above is the third of three photos showing a typical crossing of the Minnesota River heading northbound. In this photo, we have just passed under the main arch and are heading into Bloomington. The photo below is an overview of the river crossing as seen from the County Highway CSAH-1 bridge on the north end of the bridge.

The photo above is an older photo that is scanned from a print. It shows traffic approaching the main bridge spans very late in the evening in the summer. Despite traffic heading southbound, the shadow of my vehicle is visible. This is due to the sun being very far north at this hour of the day in the summer. The photo below is an interpretive sign located at the parking lot at the Long Meadow Bridge, an old bridge that formerly carried Cedar Avenue across the Minnesota River.

These two photos, and the four that follow, are views from the spring flood of 2010. The photo above is looking south along the downriver east face of the Cedar Avenue bridge. The main river channel flows under the arches in the distance. The photo below is a view of the north shore of Long Meadow Lake near the north bridge abutment. The area under the bridge is generally swampy, with a large island starting near the trees in the distance.

The photo above is a view looking south between the two bridge span, while the photo below is a view of the east face of the southbound bridge structure.

These two photos are views from the north end of the Cedar Avenue bridges. The photo above is the abutment of the southbound span, with the northbound span visible in the background. The photo below is looking west under the southbound span while standing under the northbound span. Hog Ridge trail runs along the bluffs on the north side of the river. It can be accessed from the parking lot at the south end of Old Cedar Avenue.
