I t w a s s u p p o s e d t o b e a s i m p l e renovation of the historic Waldo- Hancock suspension bridge over the Penobscot River. But when engineers finished their inspection of the 74- y e a r - o l d s t r u c t u r e , w h i c h c a r r i e s Maine's Route 1 over the waterway near Bucksport, Maine, it quickly became evident that deterioration had reached a point where the best solution was to replace the bridge with an entirely new structure. The requisite urgency of bringing a new bridge on line in the shortest possible time led the state to request proposals from design-build engineers. Figg Engineering Group (FIGG) of Tallahassee, Florida, rose to the challenge by designing a bridge with a unique cable- stay cradle system. "We looked at several possibilities for the design of the bridge," says Jay Rohleder, Jr., senior vice president and project director for FIGG. "Eventually, we determined that the cable-stay option provided several key benefits. First, it would best fit the character of this historic area. Second, it would provide the most cost-effective solution to replacing the existing bridge. Third, it would be the fastest way to restore traffic to this important transportation corridor." The bridge, in fact, was completed in just 30 months from the time that the design was started. UNIQUE cable-stay system creates landmark bridge by Wayne A.
