Believe it or not, New Hampshire does pretty well with building bridges, I saw them build a large bridge within 6 months and it seems roads are kept in a decent shape. In a nearby state where I am, I think it can outdo what you see in your state. Took 10 years to replace a very small bridge across some railroad tracks. That road was closed for 10+ years.
Over rivers ? Where I am, I suggest before you cross, open all your vehicle windows and wear a life preserver, I am serious.
