(a) Use high-strength, low alloy, corrosion resistant steel conforming to AASHTO M270, Grade 50W (ASTM A709, Grade 50W) for all major structural steel components (girders, diaphragms, splice plates, bridge railing posts, bearing plates, etc.). Use bolts, nuts, and washers for structural steel connections conforming to ASTM F3125, Grade A325, Type 3. Clean all exposed surfaces of self weathering steel in accordance with SSPC Surface Preparation Specifications No. 6, Commercial Blast Cleaning, SSPC-SP6, prior to shipping. Minimum thickness of structural steel is 3/16”.

(b) Provide galvanized structural steel corrugated bridge decking conforming to ASTM A653, Grade 50, Class 1 or ASTM A1011-SS. Steel side dam plates and end angles shall be provided to accommodate a depth of aggregate base fill as shown on the plans. Provide positive connections between steel girders and steel bridge decking. If bolts are employed for this connection, they shall be clipped to girder flange using ASTM F3125, Grade A325, Type 1 fasteners. All clips and connection hardware at these locations shall be galvanized.

(c) Provide anchor bolts conforming to ASTM F1554, Grade 55 or 105. Galvanize anchor bolts after fabrication.

(d) Provide steel reinforced elastomeric bearings conforming to AASHTO M251, 60 Durometer hardness, elastomer grade 4 or higher. The bearings at each abutment shall be designed as expansion bearings, so that thermal deformations are divided equally to each abutment. Design bearings per AASHTO LRFD method A.

(e) Provide galvanized weathering steel thrie-beam guardrail components conforming to AASHTO M180, Type I IV, Class B.

B. Design criteria is as follows:

(a) Provide a fully engineered modular steel girder bridge designed in accordance with these specifications. Prior to fabrication, submit for approval complete structural calculations, showing the governing capacity and demand values for all members and connections, and detailed shop drawings bearing the seal of a registered Professional Engineer. Design in accordance with current edition of the AASHTO LRFD Bridge Design Specifications.

(b) Provide a modular bridge with a clear deck surface width as shown on the contract plans. Steel girder and diaphragm sections may be fabricated into two or more longitudinal sections, joined together with positive connections, to form the full width
