MINOR MAINTENANCE OF COUNTY BRIDGES

INDIANA COUNTY BRIDGE MAINTENANCE IS A BIG, COSTLY JOB. THERE ARE WELL OVER 15,000 BRIDGES ON INDIANA COUNTY ROADS, AND OVER HALF OF THEM ARE OVER 35 YEARS OLD. ORIGINAL DESIGN AND CONSTRUCTION OF BRIDGES WAS LIGHT, AND TRAFFIC HAS GREATLY INCREASED IN VOLUME AND WEIGHT. COUNTY ROAD OFFICIALS HAVE DONE WELL TO REPLACE MANY OLD BRIDGES WITH WIDER, STRONGER ONES. MAXIMUM REPLACEMENT EFFORT AND PROPER MAINTENANCE OF NEW BRIDGES FOR LONG, EFFICIENT SERVICE ARE RECOMMENDED. ONLY MINOR BRIDGE MAINTENANCE IS CONSIDERED, INCLUDING ROUTINE MAINTENANCE OF SUB-STRUCTURE, SUPER- STRUCTURE, APPROACHES, CHANNELS, AND BRIDGE SIGNS AND MARKINGS. MAJOR REPAIRS AND IMPROVEMENTS WILL BE CONSIDERED IN SUBSEQUENT BULLETINS.
