As Middlefield is as small geographically as it is in population, there are only two main state highways. Rt. 147 leads South into Durham, and North toward Meriden. Rt. 157 heads West toward Wallingford and East toward Middletown. When navigating the town and its innumerable side roads, it is best to pick up a complementary map from Town Hall, located On Jackson Hill Road, just off of 157.
