Posting a pedestrian bridge
(OP)
Anyone ever see a weight limit for a pedestrian bridge?? Or has anyone ever posted a pedestrian bridge? If so did you use PSF kn the sign? An overall safe weight-like in elevators? Number of people? I have a bridge that is 140ft that i want to post for around 50 psf...

Neat picture.

Not typically involved in pedestrian bridges, but I've never seen one posted.

The other at the Hells Gate pedestrian bridge in British Columbia:
Looks like this one is really needed, too:
Note that both use Bridgebuster's excellent suggested "occupancy" that would be more understandable by the public.

Apparently they had a notice AND a limit AND a guard on both sides and it still fell down....
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

I have also seen a couple of pedestrian bridges that had a uniform load rating as well, though psf is not a load unit that most non-engineers have a good gut-feel for as bridgebuster stated. By the way, you may want to check your specific state's DOT guidelines (assuming this is in the U.S.) as most of those require a pedestrian bridge live load of 85 psf, with a minimum of 60 psf and can get as high as 90-100 psf. If its an existing bridge then you have little to no choice, but if you are designing a new pedestrian bridge with a live load of 50 psf you may want to rethink your design loads.
