comes to an interchange with Route 123, which provides access to the Norwalk Community College. Just past its crossing of the Silvermine River, Route 15 meets the U.S. Route 7 (US 7) freeway at an incomplete interchange before it crosses over the Danbury Branch of the New Haven Line just south of the Merritt 7 station, and the Norwalk River and comes to a cloverleaf interchange with Main Avenue which provides the missing movements between the parkway and US 7. From there, Route 15 continues northeast through residential areas in the neighborhood of Cranbury before it leaves Norwalk, after crossing over Route 53 without an interchange. The parkway enters the town of Westport, where it crosses over the Saugatuck River, and comes to right-in/right-out interchanges with Route 33, just east of the town line. Route 15 turns to the northeast again, upon reaching its interchange with Route 57, that has a park and ride lot serving the town of Westport in its northwest corner. Immediately after this interchange, the parkway crosses over Route 136 with no access and enters its longest stretch without exits, where it passes more wooded residential areas and comes into the town of Fairfield, where it meets its next interchange, five and a half miles later, at Route 58, which also has a park and ride lot, located in its southeastern corner. Route 58 provides access to both Fairfield Center and the campus of Fairfield University. Route 15 crosses the Mill River, passes service plazas in both directions, and then meets Route 59 at a pair of right-in/right-out interchanges. Route 59 provides access to the headquarters of General Electric. The parkway turns east-northeast and enters the town of Trumbull at its interchange with Park Avenue, which provides access to the campus of Sacred Heart University just to the southwest of the road, as well as the campus of the University of Bridgeport in the adjacent city of Bridgeport. Route 15 then reaches a single-point urban interchange with Route 111, adjacent to the Westfield Trumbull shopping mall, in its southwestern corner. The parkway meets the Route 25 freeway at an incomplete turbine interchange, which provides access to the Beardsley Zoo in Bridgeport, and the route crosses the Pequonnock River within the interchange. Past Route 25, Route 15 reaches a southbound exit and northbound entrance for Route 127 and then a full interchange for Route 108, in tandem
