Hamilton County Bridge No. 230 | Bridge Replacement
HAMILTON COUNTY, IN—Hamilton County selected BLN to develop the design for this new bridge. Improvements include replacing the existing two-lane facility with a new four-lane structure with divided median and 10' wide multi-use paths, raising the structure and approaches above Q100 high water elevation thus eliminating existing "over the road" flow, and maintaining traffic throughout construction by utilizing phased construction.
The existing 5-span reinforced concrete arch was replaced with twin 4-span continuous composite prestressed concrete bulb-tee beam bridges.
