County approves supplemental engineering agreement for Walnut River bridge replacement

Jan 20, 2026

The Board approved a time‑and‑materials supplemental engineering contract with MKEC estimated at $20,000–$30,000 to convert plans, attend KDOT meetings and secure permits for a Walnut River bridge replacement funded in part by a $2 million grant.

The full story

Public Works Director Curtis Mader told the Board the Walnut River bridge replacement on SW 80th St. has been on the county’s Capital Improvement Plan since 2023 because of traffic volume and safety concerns. He said Butler County was awarded a $2 million grant to fund the replacement and presented a supplemental engineering agreement with MKEC to convert the plans to Kansas Department of Transportation format, attend KDOT meetings and handle permitting.
