The bridge shall be custom designed to fit the dimensions and conditions depicted or reasonably inferred from the drawings. 1. Width: Inside clear width of bridge shall be 8 feet 0 inches. 2. Span: Center to center of bearing of bridge shall be 80 feet 0 inches. 3. Camber: Bridge shall be cambered 2% of the total span. All vertical truss members shall be perpendicular to the horizon (true horizontal) after the bridge is erected and the dead loads are applied. Design 1.

The designer/fabricator shall produce plans and specifications for the complete fabrication and erection of the bridge. The documents shall bear the seal of the registered professional engineer responsible for the bridge design. 3. In addition to actual dead loads, the bridge shall be designed for the following loads: a. Uniform Live Load: The bridge shall be designed for an evenly .distributed live load of 85 pounds per square foot using AASHTO live load pedestrian bridge guidelines b. Vehicle Load: Bridges will also be designed to support a moving concentrated load equal to 1000 pounds per foot of width (up to 10,000 pounds) plus 30% for impact loading. This concentrated load is, in addition to a 20 pounds per square foot evenly distributed live load. The vehicle load shall be distributed such that 80% of the load is on .the rear axle (per AASHTO). c. Wind Load: All bridges shall be designed for a minimum wind load of 35 pounds per square foot. The wind is' calculated on the entire vertical surface .of` the bridge as if fully enclosed. d. Design Criteria: The design of the bridge shall be in accordance with the "American Institute of Steel Construction"; "Allowable Stress Design"; 13th Edition, 2005. Tubular members and their connections shall be designed per the AISC " Hollow Structural Sections Connections Manual" latest edition. e. Seismic: All bridges shall be designed for seismic loads of the intensity required by the international Building Code 2006 for the bridge location. f. Temperature: Bridge shall be designed to accommodate a temperature differential of 120 degrees Fahrenheit. Slip pads of UHMW polyethylene shall be placed between the smooth surface of this setting plate and the smooth bearing plate of the bridge. At least 1" clearance shall be provided between the bridge and concrete abutments. g. Deflection: The vertical deflection of the bridge due to pedestrian live load shall not exceed 1/400 of the span length. The maximum deflection due to vehicular loads shall not exceed 1/800 of the span length. For pedestrian comfort, the minimum load used for the deflection check shall be a minimum of 500 pounds per lineal foot of bridge. The horizontal deflection due to lateral wind load shall not exceed 1/500 of the span length 3'-10 1/2" INSIDE CRB 3'-10 1/2" INSIDE CRB 6x6 CONTINUOUS TIMBER CURB, TYPICAL. 1" CHAMFER ALL EDGES TYPICAL 2x6 BRIDGE DECKING.

Unpainted Weathering Steel bridges shall be fabricated from ASTM A242 or ASTM A588 steel for plates and structural shapes and ASTM A606 or ASTM A847 for tubular sections. Minimum yield (Fy) shall be greater than 50,000 psi. 3. Wood Decking shall be No. 1 grade West coast Douglas fir. Wood decking shall be treated to a minimum of .40 pounds of preservative per cubic foot of wood. The wood deck shall be designed for a 85 psf local loading condition. Floor planks shall be attached with at least two plated fasteners where planks cross supporting members. Planks shall be nominal 3" x 12" continuous members. **** Install decking with crown of grain pointing up **** 4. Field splices shall be bolted with High Strength ASTM A 325 bolts; type 3 bolts are required for weathering steel bridges. 5. Welding materials shall be in strict accordance with the American Welding Society (AWS). Structural welding code, DIA Filler metal as specified in 1. shall be used for the particular welding process required. Welders will be certified in accordance with AWS D1.1. Fabrication 1. Bridge fabricator shall be certified by the American Institute of Steel Construction to have the personnel, organization, experience, capability, and commitment to produce fabricated structural steel for Conventional Steel Structures and Simple Steel Bridge Structures with Sophisticated Paint Endorsement as set forth in the AISC Certification Program. 2. Workmanship, fabrication, and shop connections shall be in accordance with American Association of State Highway and Transportation Officials Specifications (AASHTO). 3. Welding operators shall be properly accredited experienced operators, each of whom shall submit satisfactory evidence of experience and skill in welding structural steel with the kind of welding to be used in the work, and have demonstrated the ability to make uniform good welds meeting the size and type of weld required. 4. All welding shall utilize E70 or E80 series electrodes. The weld process used shall be Flux Core Arc Welding (FCAW) or Shielded Manual Arc Welding (SMAW). 5. The connection of bridge end post to top chord should be a mitered joint with the exposed welds ground smooth. 6. All hollow sections shall be closed off at exposed ends. Provide a Y4" diameter drain hole at the lowest point of all hollow member assemblies. Railings and Accessories 1. All hand railings shall have a smooth outside surface with no protrusions or depressions. All ends of tubes shall be closed and ground smooth. Railings shall meet all requirements of the American Disabilities Act. 2. Safety Rails: Continuous rails shall be located on the outside of trusses.

All handrails shall have a smooth galvanized finished. Delivery and Erection 1. Bridges must be erected by a contractor experienced in all aspects of bridge handling, storage, lifting, setting and connecting. 2. Follow manufacturer/designer/fabricator plans and specifications in all aspects of erection and construction. Provide additional support or bracing as required to keep the bridge straight and plumb, and to assure adequate structural stability and strength during construction. 3. Do not apply construction loads to the bridge until it has been properly anchored and braced. Do not subject bridge to full design loads until all permanent decking and bracing is installed. 4. Bridges shall be delivered by truck to a location nearest to the site accessible by roads. Hauling permits and freight charges are the responsibility of the manufacturer. 5.
