The practice of marking unimproved state highways in gray (shown in 1949 map) is gone, perhaps because all routes are now paved. Expressways and divided highways (not shown here) are marked identically, as shown in the 1959 map.
This scan of East Hampton shows US 6A (now state route 66) and Route 16A (now Main Street, a town road).
Sometime between 1949 and 1952, General Drafting moved to green and black for the city insets. Otherwise, the cartography was the same as in 1949.
The New London inset doesn't include much detail by modern standards. Among the expanses of white space are the US 1 expressway (now I-95) and its interchange with Route 32 (upgraded in the mid-70s to a freeway-to-freeway interchange).
