Located in Evanston, this steel girder bridge crosses Lincoln Street between Poplar Avenue and Green Bay Road.
Built in 1908, this bridge features four spans of steel deck girder, with a ballasted deck. The bridge rests on steel and concrete substructures.
This style of bridges was common for grade separations on the C&NW between 1905 and 1915. The bridge was built for three tracks, although only two are still in use.
Overall, the bridge appears to be in fair condition, with some deterioration.
The author has ranked the bridge as being locally significant, due to the common design.
