Bridge Description

SPS deck on press-brake-formed steel tub girder Modular Decked Beams

Cannelville Road over Riders Run Creek in the village of Roseville in Muskingum County, Ohio

Tier 4 (within 1 month)

The superstructure was erected in 20 minutes and bolted together in one day. The bridge was closed a total of 26 days. The impact to the neighboring community was minimal. Fire, EMS, and school systems saved many dollars not having extended use of the 8-mile detour.

reduced onsite construction time – helped maintain essential services while reducing life cycle costs and maintenance cost due to the nature of the watershed

Conventional construction would have required extended use of the 8-mile detour.

The existing 38-ft-long and 22-ft-wide bridge was deteriorated and needed replacement.

Each of the two modular decked beam units weighed 31 tons and had two galvanized Press-Brake-Formed Steel Tub Girders with spray metallized Sandwich Plate System (SPS) deck panels, complete with bridge railing, for a projected 100-year service life. Advantages of this innovative superstructure include prefabrication and weight savings that allowed the rapid onsite installation, and reduced section depth due to the thin SPS decks and structurally efficient girder cross section.

The bridge roadway was closed and all traffic was re-routed to an 8-mile-long detour. Standard construction methods were used for the substructure (cast-in-place concrete footer and abutments). The superstructure was prefabricated offsite and delivered to the jobsite on two flatbed trailers. The half-width modules were erected in 20 minutes and bolted together in one day, followed by application of the waterproof membrane and asphalt overlay. After setting the superstructure, the road was opened to traffic less than 10 days later. The bridge was replaced in a total of 26 days, ahead of the 30-day maximum allowed closure.

Because this structure was a “one-off” structure, the design was cumbersome since there were no standard ODOT drawings to reference.
