 Route 10 becomes a four-lane undivided road through a mix of residential and commercial areas, running to the west of Lake Whitney, before it crosses the Mill River and reaches another interchange with Route 15, the Wilbur Cross Parkway.From the parkway, the route parallels the river to the west, passes between several shopping centers, prior to briefly gaining a median to accommodate a gas station and passing under the right-of-way of the Farmington Canal, then reaching its four-way intersection with Whitney Avenue.Here, Route 10 turns north onto Whitney Avenue, which continues south towards New Haven, while Dixwell Avenue continues east to US 5 in the town of North Haven.
