US 7 in Connecticut (also known as Route 7, Ethan Allen Highway and Super 7) is mostly a surface road but has two short expressway sections in the Norwalk and Danbury areas. US 7 begins in Norwalk with a expressway to nearly the Wilton town line. There are three exits on this short section, signed as "The Forty Third Infantry Division Memorial Highway". Exit 1, just past I-95 (the southern terminus), leads to the Central Norwalk Business District and US 1. Exit 2 leads to Route 123 which extends from US 1 in Norwalk to the New York State line, passing through the town of New Canaan. After exit 2, the expressway reduces to four lanes from six. Exit 3 leads to Route 15 southbound, also known as the Merritt Parkway. This interchange was half built and only allows southbound access from the expressway; northbound access is gained via Route 123 at exit 2. The expressway section ends at Grist Mill Road in Norwalk, about one-half mile past exit 3. Route 7 then passes through Wilton as a 4-lane highway until just after Cannondale, where it becomes a 2-lane highway. It continues through Ridgefield as a 2 lane highway.
