The Connecticut Turnpike (officially the Governor John Davis Lodge Turnpike) is a freeway and former toll road in the U.S. state of Connecticut; it is maintained by the Connecticut Department of Transportation (ConnDOT). Spanning approximately 128 miles (206 km) along a generally west–east axis, its roadbed is shared with Interstate 95 (I-95) for 88 miles (142 km) from the New York state border in Greenwich to East Lyme; I-395 for 36 miles (58 km) from East Lyme to Plainfield; and SR 695 for four miles (6.4 km) from Plainfield to the Rhode Island state line at U.S. Route 6 (US 6) in Killingly. The turnpike briefly runs concurrently with US 1 from Old Saybrook to Old Lyme and Route 2A from Montville to Norwich.

Construction on the Connecticut Turnpike began in 1954 and the highway was opened in 1958. It originally followed a sequential exit numbering system that disregarded route transition, where the exit numbers on I-395 were a continuation of the exit numbers on I-95. In 2015, the I-395 exit numbers were changed to a mileage-based system reflecting their distance from the split from I-95, effectively removing the defining element of the turnpike. In some sections southwest of New Haven, it carries an annual average daily traffic of over 150,000 vehicles.[4]
