This impressively large bridge crosses the St. Louis River and the BNSF Railroad mainline tracks. The tracks are on the far side of the river in these photos. When first designated to be a US highway, US-2 actually followed the current CSAH-8 on the north side of the river. US-2 was rebuilt on a new alignment and paved prior to 1940 on the south side of the river. This is actually the second time that US-2 crosses the St. Louis River. The other crossing is on the US-2 Bong Bridge over the Duluth harbor.

While this bridge is a fairly routine prestressed concrete girder bridge, it does have a few decorative elements. First, the piers have lines and indents that enhance the shape and style of the piers. Next, there are a series of parallel lines on the outside of the guardrails. Finally, the bridge has a very nice guardrail configuration. The standard solid and slanted guardrails have been installed. In addition, a set of elegant steel guardrails have been installed on top of the concrete guardrails. As a result, the guardrails have both high function and great looks.

Note that the east end of the bridge is very tall. The reason is a large rock outcropping that was buried for eons until the glaciers came through. When the glacial lakes started to drain, one lake carved a channel that ran on the west side of this rock, which today carries the St. Louis River. A second lake created a channel that is used by the Cloquet River, which once ran on the east side of this rock in a second parallel river channel. The two glacial rivers met just south of the US-2 bridge. After the glacial period was over, the Cloquet River eventually cut a new outlet and joined the St. Louis River about a mile upstream of the US-2 bridge. The result is that the east channel is no longer used, and is a wetland area today. But the rock still stands, with US-2 cutting across the center of the rock, the St. Louis River on on the west side of the rock, and the new river bridge anchored firmly to the rock.
