Austria fixes

[neroute2]

B145 interchange between A1 and L1263
B317 interchange (single offramp) between 29 and L62
B2 interchange (single offramp) between B38 and B34_S
B2 cannot be followed between B34_S and B4/B34. I understand the bypass east of B34_S needs to be mapped as B2, but it should probably be either split or overlap B34 with a spur east to B4_S.
B178 interchange between L272_UnkS and L272_UnkN

I don't see an issue. Keep as-is.

Can I get more eyes on this? I'd think that a route should be followable from end to end.
