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.
This map section shows the Berlin area, between New Britain and Cromwell. Compared to the 2000 map, we can see a different font for town names, slightly different background colors, and gray exit numbers instead of black. I think these changes have made the map more readable, which was probably the intent.
Notice the Berlin Turnpike, a four-lane divided highway, is drawn with a single line instead of double. Other divided non-expressways, like US 5 in South Windsor, are drawn the same way. Past maps used to distinguish these roads with double red line, a convention that I hope will be reinstated.
Danbury was inadvertently left out of the city insets in 2000, but returned in 2002. Welcome back, Danbury.
The red road leading south from I-84 exit 3 is US 7; for decades, this was to be the north end of a "Super 7" expressway leading to Norwalk.
