Site Data:

• Highway Type: Rural major collector
• Traffic Volume: 3248 vehicles per day, 7% trucks
• Land use: Suburban

Structure Data:

• Structure Type: single span Warren truss on concrete abutments
• Bridge Length: 140' Width curb to curb: 24' Skew: 27 degrees
• Deck Type: 32 psf - 14" deep fiber reinforced polymer (FRP) slab supported on floorbeams at 14' c.c.
• Materials: E-glass reinforced vinyl ester composite with "cell core" SCRIMP technology
• Bridge Railing: Double box beam mounted on trusses
• Drainage: Two scuppers with removable grates cast in deck, FRP curb
• Bridge Joints: Pourable silicone sealant
• Wearing Surface: 3/8" epoxy/basalt polymer concrete

Deck Design Criteria:

• Live Load: HS25
• Deflection Limit: L/800
• Analysis Method: Finite Element Model

Performance:

• Truss Load Ratings: Operating level before = H30 (30 tons); after = H85 (85 tons)
• Deck Ratings: Inventory HS85 (154 Tons); Operating HS 115 (207 Tons)
• Load Testing: The structure proved to be stiffer and under less strain than predicted.
• Testing: NYSDOT Engineering Research and Development Bureau, University of Buffalo
• Total Project Cost: $876,000, FRP deck design & fabrication: $429,000 ($121/sf)
