DCCI was contracted to perform the retrofit work on the existing Meridian Bridge in Yankton, SD. Built in 1924, the Meridian Bridge was along U.S. Highway 81 until traffic was re-routed to the new Discovery Bridge, a half mile to the west. This newly retrofitted bridge is now a pedestrian bridge for the residents of Yankton.
DCCI's scope of work included the reinforcement of the bottom chord of the bridge by adding new exterior and interior fill plates and gusset plates, along with replacing much of the existing horizontal wind bracing. At the gusset plate reinforcement, all of the rivets had to be meticulously removed and replaced by bolts. Because of the unique layout required at each location, each gusset plate required field fabrication.
