Minnetonka, MN

• Structure ID: NBI 91052.
• Location: River Mile 19.6.
• River Elevation: 921 Feet.
• Structure Type: Highway Bridge.
• Construction: Concrete Culvert.
• Length: 24 Feet, 11 Foot Longest Span.

The I-494 Interchange bridge is located on the entrance and exit ramps that connect between Minnetonka Boulevard and northbound Interstate highway I-494. This bridge is the easternmost of 4 bridges over the Minnehaha Creek at this interchange. The bridge is a concrete culvert that that has two 11-foot wide passages. It was built in 1965 when the freeway was constructed, and was poured in place (as opposed to being prefabricated).

Minnehaha Creek used to follow a channel located several hundred feet north of this location. The creek channel was diverted to the south and the wetlands area was filled in then the Interstate was constructed.

The photo above is looking northeast towards the bridge. It is not readily apparent that there is a bridge when viewed from the traffic lanes, nor is it apparent that this road is crossing the famous Minnehaha Creek. The closer traffic lane is the northbound exit from I-494, while the traffic lane on the far side of the bridge is the entrance to northbound I-494.

The photo above is the west side of the I-494 Interchange bridge. The photo below is the downstream east side of the structure. Both photos were taken from the south shore of Minnehaha Creek. Note that this bridge has no railings or guard rails, and that the roadway is built up about a dozen feet above the bridge deck.
