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.
