PAUL'S OPINION: MA 3 should become US 3 for its entire length. I would also extend US 3 onto Cape Cod, replacing MA 28 to Falmouth Center and south to Woods Hole.

PAUL'S OPINION: An END US 6 sign should be placed at the Provincetown terminus, and a "BISHOP, CA 3205" destinatinon sign would be nice as you leave Provincetown to match the PROVINCETOWN, MA 3205 sign in Bishop.

PAUL'S OPINION: The loop back of MA 139 results in an eastbound route signed going WEST. Terminate MA 139 at Ocean Street and Dyke Road, and extend MA 14 along the current MA 139 alignment to the shore.

Kurumi and I agree that MA 16 should be extended to replace MA 197, and CT 197 should become CT 16.

Prior to 1929, MA 17 was  
a New England route along  US 7 south of 
Great Barrington (Kurumi).
From 1956 to 1959, US 1 north of Danvers was routed onto what is now I-95, and US 1 became MA 17.  
A 1955 map shows this stretch of highway labeled as MA 26.

PAUL'S OPINION: This transcontinental route shouldn't end in Kenmore Square. An appropriate end? Perhaps the public garden. Even better, bring US 20 through Boston, up the north shore, then east along MA 127 to a dramatic ending at the docks in Rockport. Also, let's have a "NEWPORT, OR 3365" destination sign at the start of US 20.
