Tunnels are well lit and short. Rt 17 bridge (aka James River Bridge) is tall enough for most recreational boats / 50+ footers, but is actually a draw span.

We use the tunnels often when towing, don't forget to stop at HAZMAT checkpoint, or they will stop all traffic just to pull you over at the tunnel entrance to inspect your propane valves. Don't ask me how I know this -- I just do :o

That area is the largest deep water port on the east coast. The tunnels are well lit and the underwater part is short. OTOH, the US 17 bridge is long and high enough for those same ships to go under it. There's a lot more of those ships above the water line than below it. The Jamestown-Scotland ferry is fun, but the lines are long and the trip is SLOW.
Besides, you get to tell your buddies at home that you were run over by an aircraft carrier. :)

The US17 bridge is somewhat narrow. Tunnels are a better choice. Tunnel on 664 is newer and more rounded so you don't feel as closed in.

Not sure of size restrictions, but you could also take the Jamestown ferry then continue south to US460.

Yes, both I-64 and I-664 have a tunnel. So if you insist on not going through a tunnel that leaves you the Rt. 17 bridge. Actually the tunnels are not bad. You have to stop before the tunnel to verify that your propane is shut off. But both tunnels are very short with plenty of room. RVs use them all the time.
