Bridge Crossings

[Kithikor]

Using academy scenario 5, map 5. There is an East and West major river. Hex 0609 has a bridge. I would think that a tank could not enter hex 0509 to enter the bridge. On the north side of the river all bridge crossings would have to be from hex 0608.

From the south side though, hex 0710 could enter the bridge into hex 0609. Am I correct on any of these?
