You have quite a few connection problems that I found. Just from the quick search I did:
Missing Connections:
* Windsor - East Granby
* Glastonbury - East Hampton
* Newington - Hartford
* Durham - Killingsworth
* Plymouth - Watertown
* Windsor - East Windsor
* Suffield - East Windsor
* Vernon - Bolton
* Vernon - Manchester
* Bolton - Glastonbury
* South Windsor - Hartford
Incorrect Connections:
* Ledyard - New London
* New Haven - North Branford
There's also a bunch of discrepancy in whether or not you are using diagonal connections. Some are there and some aren't. You need to chose one or the other, and stick with it throughout the map.
Other than this, it's definitely great work so far. Just a few tweaks here and there and it looks good!
[EDIT:] I also noticed a two territory overlap between the Southern and Northern Middlesex County bonuses, and some of the territories in the New Haven County bonus aren't a part of any of the New Haven County sub-bonuses. I don't know if that's intentional.
