Connecticut Multiplexes - Text Index

Connecticut, like most states, has its share of route multiplexes (roads with multiple numbers). Below is a list of the 106 duplexes, 3 circleplexes, 7 triplexes, and 1 quadruplex in Connecticut. The list on the left is organized by multiplex type, route hierarchy (Interstate at top, then U.S. Routes, then state routes), and numbers (lowest to highest). The right list is the "master list" and are listed once per number (i.e. U.S. 6 & U.S. 202 is listed under both 6 and 202). Photo submissions can be made to webmaster@nutmegroads.com.

For an index with graphics, use the shield index.
