The Berlin Turnpike is a 4-lane/6-lane divided arterial road carrying U.S. Route 5 and Route 15 through the towns of Berlin, Newington, and Wethersfield, Connecticut, United States. The road begins south of the Meriden-Berlin town line. The official length of the Berlin Turnpike is 11.02 miles (17.74 km) but the northernmost 1.04 miles (1.67 km) does not carry US 5 or Route 15. The northernmost section runs partly along Route 314 for 0.66 miles (1.06 km), and then on State Road 543 for 0.38 miles (0.61 km) to the Hartford–Wethersfield town line, where it continues as a local road known as Maple Avenue.
The main office of the Connecticut Department of Transportation (ConnDOT) is located on the Berlin Turnpike in Newington on land originally purchased for Interstate 291, which was subsequently cancelled.
The Berlin Turnpike is a popular road for shopping in the greater Hartford area; many national and regional retail chains, including Target, Stew Leonard's, Best Buy and Sam's Club have outlets on the turnpike.
In 2011, a 525 page book entitled, "The Berlin Turnpike: A True Story of Human Trafficking in America," was written by author, Raymond Bechard. The book explains a federal trial that took place in Hartford, Connecticut during which it was revealed that two young women were "sold" from one man to another in a motel on the Berlin Turnpike. According to the book, there were over 1000 motel rooms on the Berlin Turnpike as of 2011. 
The Hartford and New Haven Turnpike was chartered in 1798.
The turnpike was built along the principle of a straight line and connected the courthouses of New Haven and Hartford in as straight a route as the terrain allowed. Its southern end was at Grove Street, which forms the northern boundary of the original nine squares of New Haven. Because of the straight line principle, several intermediate town centers are bypassed by the turnpike.
The roads used by the turnpike still exist today but the route is no longer a main road in the New Haven area. In the Hartford area, the turnpike road has been substantially widened and straightened out as the Berlin Turnpike, a major commercial thoroughfare.

Popularity of Turnpike
For many years, "Hot Rodders" of all types have converged on the Turnpike to "Run what you Brung", and have proved to be the bane of the local Law Enforement's existence. There have been numerous articles in local news outlets about the spate of Illegal street racing over the years that have detailed what has been transpiring on the Turnpike, and the various steps the local Law Enforcement was taking to curtail the issue. However, the long, straight roadway, which in some places has no access roads, has proven irresistible to some street racers.
