[edit] Route description

I-691 is the main east-west highway of the city of Meriden. The freeway actually begins in Middlefield as Route 66, technically becoming I-691 at the junction with I-91 (Exit 11). However, westbound signage indicates I-691 begins at the start of the freeway (just west of Exit 13), while eastbound signage shows I-691 ending at the Route 15 interchange (at eastbound Exit 10 about 0.5 miles west of the interchange with I-91). To go from I-91 northbound to I-691 westbound (or from I-691 eastbound to I-91 southbound), one must actually use Route 15.

[edit] History

In the 1940s, the I-691 routing was part of a planned US 6A Expressway from Southington to Willimantic. A section of the expressway (from its Middlefield terminus west to Exit 8) first opened in 1966. By 1968, the US 6A designation was dropped in favor of Route 66. The highway was extended west to Exit 4 by 1971. The connection to I-84 was eventually completed in 1987, with the renumbering to I-691 done at the same time. The portion east of I-91 remained as Route 66.
