Abstract

This project consists of the replacement of the structurally deficient bridge over Holton Creek on State Route 171 located 0.6 miles south of Kite in Johnson County. The length of the project will be 0.32 miles. Traffic will be maintained on an on-site detour during construction.  The existing bridge was built in 1963 and consist of 3 spans of reinforced concrete deck girders on concrete caps and steel piles with a total length of 96 feet. The width is 26 feet, consisting of one 12-foot lane in each direction. The current sufficiency rating of this bridge is 68.89. The proposed bridge is estimated to be 96 feet long and 36 feet wide. The proposed bridge will have one 12-foot lane in each direction with 6-foot shoulders. Existing right-of-way (ROW) varies between 80 and 150 feet, and the proposed ROW would vary between 100 and 150 feet.
