The installation of a water line along Dublin Road in Franklin County, Ohio, required that two deteriorating structures be replaced. It was decided that both structures would be replaced simultaneously in order to ensure a timely completion of the project and to lessen the overall impact to traffic.
Two precast CON/SPAN® Bridge Systems were chosen for the project. A 12’ x 9’ CON/SPAN was installed over Kuhn Ditch while a 16’ x 9’ CON/SPAN was installed over an unnamed tributary. Installation of these precast options occurred in just one day allowing for the road closure to be greatly minimized.
Alternative precast concrete structures were considered but later ruled out because CON/SPAN’s precast headwalls and wingwalls could be installed in the same day as the bridge, thus saving time over cast-in-place end treatments. This allowed the contractor to complete the project early and the County to open the road ahead of schedule.
“The use of the CON/SPAN arch culvert system with precast headwalls and wingwalls allowed us to complete the work 15 days ahead of schedule much to the satisfaction of the surrounding neighborhoods” states Jim Pajk, P.E., Franklin County Bridge Engineer. “In addition, Contech was able to incorporate our standard formliner detail into the wingwalls which we traditionally use in urban settings to provide better aesthetics”
