Roddy Bridge Road Restoration

Thanks to hot-dip galvanizing, this national historic bridge will stand for another 150 years. This bridge spans 40 ft. (12 m), is 16 ft. (5 m) wide, and has almost a 13 ft. (4 m) clearance. In 1995, the county approved a request to repair the bridge and replace the badly corroding stringers with something that would withstand Maryland's weather conditions, and they specified hot-dip galvanized stringers and diaphragms to do the job.

The galvanizer realized that there was no parallel route while the bridge was under repair. He received the steel one day, galvanized it overnight, and shipped it to the site the next day. Located near the foothills of the Appalachian Mountains, this bridge, which has stood for 150 years, must withstand de-icing salts, the expansion of the ground during hot/cold climate cycles, and it must protect and mix well with the indigenous vegetation.
