World's longest orthotropic section feature of San Mateo-Hayward bridge

Foley, E.R. / Murphy, J.P.

Bridge has orthotropic steel deck on 375-750- 375 ft channel spans with seven 292 ft girder spans on each side; twin box girders 10 ft wide at 44 ft centers support deck 80 ft wide; epoxy asphalt 2 in. thick forms wearing surface; additional 10 steel spans of 208 ft length at each side of channel have concrete deck; steel H piles, fabricated from plate, support precast concrete units that form piers for steel structure; 5 mi of 30 ft span precast concrete approach trestle rest on 24 in. diam 4 1/2 in. wall, pretensioned concrete piles; these were slipformed on 900 ft horizontal bed, with sliding form at top and 15 in. center mandrel; lighting on bridge is at low level in central median.
