Route 2A is a state highway in the U.S. state of Connecticut. It is a 9.9-mile (15.9 km) mostly expressway 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[edit]

Route 2A begins at the junction of I-395 and Route 2/Route 32 in Norwich. Route 2A travels along I-395 for 3.7 miles (6.0 km) before separating as its own 2-lane freeway. This independent freeway portion of Route 2A runs for about 3.4 miles (5.5 km) through the towns of Montville and Preston. Route 2A crosses the Thames River on the Mohegan-Pequot Bridge. After the river crossing, Route 2A becomes a surface road for another 2.9 miles (4.7 km) ending at Route 2 in Preston.


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.[1]


The Connecticut Department of Transportation announced in May 2013 that exit numbers on I-395 and Route 2A will be renumbered from the existing sequential-based system to mileage-based numbering starting in 2014. The old exit numbers will be posted alongside the new exit numbers through 2017 to help motorists adjust to the new exit numbering system during the transition period.

Exit list[edit]

Proposed new exit numbers are listed in parentheses. The entire route is in New London County.
