CT 17a

3.02 miles; from Route 17 in northern Portland to Routes 17/66 at the Arrigoni Bridge approach. Runs close to the river and is sometimes under water.

History:

From 1932 to about 1940, part of the old Route 15; from then to 1948, called Route 15A. When 15 became 17 on May 1, 1948, Route 15A became 17A as well.

A Rand McNally state map (1956 or 1957) shows Main Street in Glastonbury, from the Route 17 split to an undetermined point downtown, as Route 17A. The Glastonbury Expressway carrying Route 17 had opened a few years earlier.
