What do we do if we receive a red flag on a bridge inspection (and what does it mean)?

How do I change the allowable weight limit on a bridge?

Does a smooth bore pipe have more capacity to carry water than a corrugated pipe?

What constitutes a Federal off-system bridge or road?

We are looking to reduce costs for some culvert replacement this spring, where can we find some savings with material(s)? Is it OK to backfill culverts with the same material we dug out from around the old pipe?

What can we do to stop beavers from clogging up our culverts?

Can I replace my 24-inch corrugated pipe with a 21-inch smooth bore plastic pipe?
