Above is a map of Wellesley Island showing the main roads,
villages, and State facilities.
 
If coming from the American mainland, visitors would get off at exit 51N,
which puts them on the Old Bridge Road, running parallel to Rt. 81.
There is a second exit , exit 52, just before Customs. A right at the stop
 sign when getting off at Exit 51 takes you to Co. Rt. 100, which runs
the length of the Island.
If coming from Canada, exit 51S is your best bet; that puts you on
 Co. Rt. 100, the main road running east and west for the length of
 the island. No scale is shown, but the island is roughly seven
 miles long, and just under three miles wide. For a map showing how
