Route 59 is a north–south state highway in Connecticut, running from Bridgeport to Monroe.

Just south of the Fairfield-Easton town line, Route 59 crosses over the Merritt Parkway (at Exit 46).

By this time, the village of Stratfield had been absorbed into the city of Bridgeport while Easton had become a separate town (since 1845).

[3] The route's bridge over the Mill River in Easton, which carries more than 10,000 cars and trucks every day, has a substructure rated in critical condition by state safety inspectors.

As of early August 2007, the bridge was one of 12 in the southwestern part of the state (including New Haven) with safety inspection ratings so low they are considered to be in critical condition.
