The Berlin Turnpike is a 12.17-mile (19.59 km) major thoroughfare carrying U.S. Route 5 (US 5) and Route 15 in New Haven County and Hartford County in the U.S. state of Connecticut. The road begins one mile south of the Meriden-Berlin town line where Route 15 on the Wilbur Cross Parkway merges with US 5 along North Broad Street in Meriden and terminates at the Hartford city line. The local name of the street varies as it passes through multiple towns.
1.07 miles (1.72 km) south of the Hartford city line, US 5 and Route 15 leave the turnpike and follow the Wilbur Cross Highway northeast through Hartford towards the Charter Oak Bridge. The Berlin Turnpike continues north as a two-lane undivided road as part of Route 314 for 0.69 miles (1.11 km), and then as SR 543 for 0.38 miles (0.61 km) before entering Hartford as the municipally-maintained Maple Avenue.
