Route 152 is a state highway in Connecticut running entirely within the town of Orange.

Route 152 begins at an intersection with US 1 (Boston Post Road) in Orange and heads generally north.

About 0.4 miles (0.64 km) north of the town center, it intersects with Old Grassy Hill Road, which is signed as a shortcut for the Wilbur Cross Parkway (Route 15).

The road then curves to the right at a five-way intersection controlled by an all-way stop.

Old Highway 322 instead used Mapledale Road (one of the branches of the five-way intersection) to reach Route 34.
