Rolled Steel Beams and HPS 70W Steel
(OP)
Is it possible to get W18, W14 rolled beam shapes in HPS 70W steel or are they available only in Grade 36W and Grade 50W steel. I am trying to minimize my section depth due to hydraulic concerns on a small bridge project. Any help would be greatly appreciated.
Thanks!
Thanks!

How long is the span? If less that say 110 ft., why not use prestressed butted box beams? This is the shallowest system going and performs very well in low clearance stream crossings.

I guess you could just close up your girder spacing to use smaller beams.
Then there are always those cute truss bridges.
Or widening the bridge at the narrow end to make it constant width--is that a possibility?

Is your framing plan splayed now?
If you can't tighten the girder spacing as HgTX suggests to add a beam, can you use short framing beams (our term) coming off the main beams at the wide end? In other words, make the main beams parallel to reduce the wide end spacing, and add maybe a 15' beam coming off at an angle on each exterior beam to pick up the turning radius or whatever is driving the flared-end requirement.
