The 18th Street Bridge over the Kansas River is one of the few remaining deck truss bridges on the state highway system. Built in 1959, the bridge has undergone numerous rehabilitations over its more than 60-year life. The bridge is nearing the end of its service life and any further rehabilitation beyond the repairs conducted in 2018 can no longer cost-effectively maintain this structure. Therefore, it is important that KDOT has determined a solution for replacement of the bridge before further rehabilitation is required or safety is jeopardized.

The On-Alignment Alternative was determined to be the most feasible option as it best meets the project goals and evaluation factors. The key factors that differentiated this alternative were cost, impacts to adjacent properties, environmental considerations, maintenance of traffic and safety during construction. This alternative focuses on the bridge replacement and limits impacts along the corridor. It minimizes encroachment on adjacent properties and protects sensitive environmental resources.
The On-Alignment Alternative will utilize a full closure of 18th Street to construct the new bridge. This approach will allow for construction to be completed in the safest manner for both construction staff and travelers. KDOT analyzed detours to accommodate the full closure, and several low impact detours were determined to be viable options for travelers. The analysis indicated that travelers can expect minimal travel delay and high trip reliability during construction. More information will be provided as the project progresses.
The On-Alignment Alternative was selected because it:
