The 7th Street Trafficway Bridge is a one level deck truss bridge over the Kansas River and BNSF Railway tracks on 7th Street.

[1] It connects the Armourdale district of Kansas City, Kansas, to the east end of the Argentine district of Kansas City, Kansas.

In 1970, the bridge was resurfaced, repainted, and a new sister bridge was built.

The new sister bridge is a two lane girder bridge that would now carry southbound lanes, making the deck truss bridge into a northbound bridge only.

It is also called the Herman G. Dillon Bridge, and it survived the 1951 flood.
