31st Street Bridge

Bridge Replacement


The Kansas City Public Works Department hired IAA, in collaboration with civil engineers, George Butler and Associates, to reconstruct the iconic bridge uniting Broadway Blvd. and Main St., a late 1800’s overpass. Primary objectives were to widen the bridge and increase vehicle clearance for Wyandotte St. below - all without diminishing its historic qualities. Furthering the challenge was the inability to lower Wyandotte St. due to the cost-prohibitive relocation of existing utility lines below, and associated re-grading and paving.

design solution

Working closely with the MO Department of Transportation, surrounding neighborhoods and residents, and the Department of Parks and Rec., IAA designed a bridge respectful of it surroundings and historic significance. The bridge framework was replaced with shallower structural members, allowing for the required clearance at Wyandotte St. A pedestrian walkway was incorporated into the street-level design in order to provide families safe passage to the nearby playground and Pennway Park. Lighting features, banners, extensive landscaping, and stone elements maintain the bridge’s urban charm.
