Route 6A marker

Massachusetts Route 6A is the state road for two sections formerly known as U.S. Route 6 (US 6) on Cape Cod. Most of Route 6A is also known as the Old King's Highway. Combining the 2 major sections (and a "silent" concurrency with US 6 through Eastham, Wellfleet, and South Truro), the highway is approximately 62 miles (100 km) long.

Although some maps have Route 6A starting at the Bourne Bridge Rotary along Sandwich Road, it actually starts some feet east of the Sagamore Bridge, according to state signage. From there, it goes thus:

Since 1982, Route 6A has ended at an intersection (signalized until 2010) with US 6 at Herring Cove, part of the Cape Cod National Seashore. Before 1982, the intersection was a large complicated rotary-like design, and Route 6A traveled slightly farther north than its intersection with US 6, ending at the exit off the rotary for the remainder of Provincelands Road toward Race Point.

It is signed east/west on both sections of the highway. Until 2015, the highway was signed north/south from Truro and Provincetown.

Some maps erroneously had the northern Route 6A having its southern terminus at US 6 along Mayflower Avenue in Provincetown. However, since Mayflower Avenue is an extremely narrow private road of questionable maintenance, and there is no access from east US 6 to Mayflower Avenue, the reason for this misunderstanding was unknown. This has since been fixed in most maps which once contained this error.
