Although the route serves no major city centers for most of its run, with the largest city being Danbury, it does pass through Hartford County, serving the northern fringe of Greater Hartford.

The two roads reunite at the end of the US 7 freeway about 5.3 miles (8.5 km) later just before the New Milford town line.

Between the junctions of US 7 at Exit 12 and US 7 at the Brookfield-New Milford border, signage for US 202 briefly changes directions to become a north-south route through the center of Brookfield.

US 202 returns to being signed in its dominant east-west directions again after overlapping with US 7 in New Milford.

The 2 roads split again in the center of New Milford as US 202 turns east to cross the Housatonic River.

It then turns northeast to pass through Washington and Morris (briefly), before entering Litchfield.
