Route 6A is the name for parts of former U.S. Route 6 (US 6) on Cape Cod. Most of "6A," as it is often locally referred to, is also known as the Old King's Highway. Combining the 2 major sections (and the apparent "silent concurrency" with US 6 through Eastham, Wellfleet, and South Truro), the highway is approximately long. ==Route description== 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: * Bourne: Sandwich Road * Sandwich: Route 6A * Barnstable: Main Street * Yarmouth: Main Street * Dennis: Kings Highway * Brewster: Main Street * Orleans: Cranberry Highway * Truro: Shore Road * Provincetown: Commercial Street (1 mile), Bradford Street (2.5 miles), Province Lands Road (1 mile) 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. Some maps also erroneously mark US 6's old routing through downtown Wellfleet as Route 6A, though MassHighway (and the Massachusetts Department of Public Works before it) has never included the stretch as part of Route 6A. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Massachusetts Route 6A」の詳細全文を読む スポンサード リンク
