I-691 was planned later than most other highways in Connecticut. The route first appeared in the 1962 plans when the US 6 Expressway was planned from Southington to Willimantic over a distance of 60 kilometers. It was then planned that the highway would be opened in 1975. In 1965, the first three-mile section between Meriden and Middlefield opened, then little more than a service road to I-91. The number was changed from US 6 to State Route 66 in 1969. In 1979 most highway plans around Hartford were scrapped. State Route 66 was then renumbered as I-691. In 1988, the western portion of the highway opened to traffic as far as I-84. This was one of the last new highways in Connecticut.

Traffic intensities

In 2012, 64,000 to 73,000 vehicles drove daily on most of I-691, except between the two branches of SR-15 and I-91, which had 35,000 vehicles.
