All state-maintained roads are drawn in red on the main map. Even secret routes, such as the unmarked route (old SR 411) branching north from Route 65 in Nichols, are included.
Red roads with black outlines are literally "super highways," an honor given to any road with four or more lanes. New parkways such as the Merritt and Milford are drawn the same way as city streets such as US 1 in Stratford. Even on the main map, some degree of ramp detail is shown at interchanges.
Disoriented? Don't feel bad. The Merritt Parkway (slightly above center) was not called Route 15 until 1948. Route 65 became Route 8, which then became a freeway; Route 113 became part of Route 108, and most of the old Route 8 is now Route 110.
City maps were black and white, with finer detail. The scan doesn't quite do justice to the hairline details of riverbanks and streams.
This Hartford map predates the Charter Oak Bridge by a year; the Founders, Putnam, and Bissell Bridges did not appear until the late 1950s. US Routes 5, 6, and 44 all cross on the Bulkeley Bridge, a stone arched crossing built in 1907 that now carries I-84.
