This exhibit shows how the Connecticut official tourist map has changed since the 1930s. You can start with the introduction or browse year to year. The scans may not be actual size (150 dpi), but are consistent with each other.
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.
