The Willow Brook Connector is a 1.45-mile (2.33 km) freeway in the town of Berlin, Connecticut.

The freeway begins at the intersection of Route 71A (High Road) and Route 372 (Corbin Avenue) at the northern end of Berlin (near the New Britain city line).

The freeway ends half a mile later as it merges into southbound Route 9.

The road opened in the early 1960s when what would become the Route 72 Expressway (part of Route 9 today) opened from this road south to the junction of the Berlin Turnpike (US 5/Route 15) in Berlin.

As part of a signing project in 2020, the Route 71 exit will receive a number.
