Wouldn't these bridges also be considered pedestrian bridges with a live load requiredment of 100 psf? If your bridge is ten clear feet wide, then the loading would be 1000 lb/lineal foot times the span - big load!
Remember, pedestrians flattened out the Golden Gate Bridge a few years ago.

I am designing two cart path bridges for a golf course. First bridge is 3 span 70'+50'+50', second bridge has a single span of 70'.
Wonder of wonders, the owner and the contractor both want to minimize the cost on the structures, and are asking that I use the minimum live loading possible.
The largest vehicle used on the golf course is a mower/utility vehicle with a gross weight of about 2 tons, well below H15 loading. The bridges themselves are to be 10 feet wide, and the approaches are so hilly that it is unlikely that a truck could even get to the bridges.
Soooo, my question is : Does anyone have experience regarding the use of loads substantially less than those required by AASHTO for the design of NON-highway bridges. If so, are there standard loads? I was thinking of using 5 tons as a minimum, and having the owner post a permanent sign showing the weight restriction.
Also, does the AASHTO manual govern the design of the bridges? We are currently under UBC94, soon to switch to the IBC, but I am not all that familiar with AASHTO requirements (not much bridge work on Guam). I would prefer to use UBC94, LRFD 2nd Ed for the girders, and refer to AASHTO for load distribution (based on 5 ton total weight) and seismic design.
