Currently, here in Ohio, it is very lucrative to be a diver that has a=20
registered engineer's license, that also has a bridge inspection=20
certificate. Even small bridges require inspection, but then there is=20
the guy with a heavy load, bootlegging, driving back roads to avoid=20
being caught with no overweight permit, and the bridge fails suddenly.

This brings me to the TV show "IRT" (Ice road truckers), where several=20
USA drivers were in back area India near a dam construction. many of the=20
bridges and roads were very dangerous. Apparently there are no=20
authorities to regulate loads on the bridges, or even to post weight=20
limits. Every state in the USA has an authority that issues=20
oversize/overweight permits after they investigate the route and=20
determine that clearances and weight limits are acceptable. The fines=20
for violations are very stiff, and the load doesn't move until a permit=20
is issued, which may take some time, or not at all.
