In Bridgeport, it is known as East Main Street. It runs north as a two-lane undivided road. Near the city line, it crosses the CT 8 expressway and changes names to become White Plains Road. About a mile to the north, it crosses the Merritt Parkway (CT 15), widens to four lanes, and curves to the west. After another half a mile, it crosses the CT 25 expressway. It then narrows back down to two lanes and changes names again to become Church Hill Road. After about another mile, it ends at Main Street (CT 111) in Trumbull.
