Located in the heart of Davenport, a pair of through trusses cross streets along an elevated track leading towards the Government (Arsenal) Bridge.
This particular structure crosses 3rd and Iowa Streets.
Built in 1928, the bridge likely replaced a smaller girder bridge. The truss on this bridge is massive, containing 6 panels and riveted connections.
Utilizing a Subdivided Warren design, the truss is also approached by an I-Beam span on either side. The substructures on the bridge are built of concrete and steel.
Along with the nearby 4th Street Bridge, these two structures are extremely recognizable to the community. As Davenport continues to develop into a more upscale area, one can expect these two iconic bridges to be painted and look even nicer.
Overall, the bridge remains in very good condition. Recently, the deck on the bridge was replaced and corrosion corrected.

The author has ranked this bridge as being locally significant, due to the newer age.
