There are parts of an old routing of US 52 just east of its south junction with US 61/151 on the south side of Dubuque. One portion, Bellevue Heights Road, was bypassed in the 1930s and now has the E.B. Lyons Interpretive Center on it. The other is a little extension of that that wasn’t bypassed until the 1950s, and now looks out of place. It does not appear to be closed in the most recent aerial photo (below), but time and the Dubuque County supervisors* have caught up with it.
The bridge construction is a style common to the era, reinforced concrete with a little bit of shaping to the pillars lining each side. It still has a nice plaque in the middle. Now that the bridge has been closed, the question is if it will be torn down or left in place. Photos taken Sept. 16.
