Here's a scan from southeast Connecticut. The roads are different now: Route 51 and US 1A are both part of US 1, and Route 52 is now I-395. The proposed freeway at upper right, Route 11, is still proposed.
Here's the detail of the Bulkeley Bridge area in East Hartford -- a close-up of the Hartford vicinity detail shown on the 1972 page. With very ramp distinctly shown, you can see how many gory left exits and weaves there are. Nasty freeways, but a very nice map.
