# Connecticut Route 2A

Route 2A is a state highway in the U.S. state of Connecticut. It is a 9.9-mile (15.9 km) mostly freeway alternate route of Route 2 that bypasses the downtown area of the city of Norwich and serves as the main access road to the Mohegan Sun casino.

## Route description

Route 2A begins at the junction of I-395 and Route 2/Route 32 in Norwich. Route 2A travels south along I-395 for 3.7 miles (6.0 km) before separating as its own four-lane freeway at I-395 Exit 9 in Montville. It runs easterly for about 3.2 miles (5.1 km) with interchanges for Route 32 and Mohegan Sun Casino before becoming a two-lane freeway, after which it crosses the Thames River on the Mohegan-Pequot Bridge into Preston and ends at Route 12. After turning north onto Route 12 for a brief overlap, it resumes its easterly course, meeting with Route 117 in the village of Poquetanuck. From here, Routes 2A and 117 continue north as a concurrency to Route 2 where both routes end.

## History

When the highway and bridge opened in December 1967, motorists were charged a 15-cent toll. The toll plaza located at the west end of the Mohegan-Pequot Bridge was removed in 1980.

## Junction list

The Connecticut Department of Transportation announced in May 2013 that exit numbers on I-395 and Route 2A would be renumbered from the then-existing sequential-based system to mileage-based numbering; the numbers on I-395 were changed from June to November 2015, the Route 2A numbers by March 2016. The old exit numbers were posted above the new exit tab for the mile-based numbers until 2017.
The entire route is in New London County.
