6A from Plymouth to Farmington, this became US 6A. This US 6A was subsequently extended through Meriden to Willimantic along modern Route 66. An expressway upgrade was planned for this US 6A. Only a portion of the highway was built and is now I-691. Coventry–Windham alternate route U.S. Route 6A (US 6A) between Coventry and [[Windham, Connecticut],] was designated when New England Route 3 (Route 3) was deleted. The route was swapped with the old US 6 in 1939 and finally deleted in 1942 when US 6A became Route 31. Danielson alternate route U.S. Route 6A (US 6A) in Danielson, Connecticut, was the old routing of US 6 prior to construction of the two-lane freeway. Scituate business/bypass routes In Scituate, Rhode Island, US 6 splits into U.S. Route 6 Business (US 6 Bus.) and U.S. Route 6 Bypass (US 6 Byp.), with mainline US 6 following US 6 Byp. The business alignment travels further south along the old turnpike and is mostly signed as US 6 without a banner. The route is also known as Danielson Pike for its entirety. The bypass is signed mostly as US 6 Byp. on sign assemblies but as bannerless US 6 on green guide signs. Most maps and information takes US 6 along the bypass. The business and bypass cross Route 102 soon after splitting. The western half of the bypass is a two-lane limited-access road, with one grade separation, under Gleaner Chapel Road, and one intersection, at Route 102. This newer section ends as it merges with Route 101, once the Rhode Island and Connecticut Turnpike, and now called Hartford Pike. The two parallel alignments cross the Scituate Reservoir and Route 116 before they merge near the east edge of Scituate. This merge was the east end of the Foster and Scituate Turnpike and was the east end of Route 101 until the early 2000s (when it was truncated to the merge with US 6 Byp.). The Rhode Island and Connecticut Turnpike continued to the Olneyville section of Providence, where it is known as Hartford Avenue.
