The west end of the bridge is a little bit of a roller coaster. The bridge has to clear a railroad track between the river and I-94. The railroad track itself is elevated, and crosses a side street near the bridge. This configuration can be seen in the bottom photo. From the high point, the bridge has to connect to Lyndale Ave immediately west of I-94. I-94 runs in a trench, and Lyndale is the same elevation as the side street on the east side of the freeway. That means in the width of I-94, the bridge has to descend from it high point down to street level.
