U.S. Route 1A
Encyclopedia
U.S. Route 1A is the name of several highways found in the United States
:
and Franklin
counties, is located north of Raleigh
and in two separate segments.
The largest segment of US 1A initially branches off near the massive Wakefield development near Wake Forest
and passes through that town, before crossing the Wake/Franklin County line into Youngsville
.
A shorter segment passes through nearby Franklinton
just a few miles north of the Wake Forest – Youngsville segment.
Both sections of US 1A are not to be confused with a US 1 Alternate in Moore County, North Carolina
that was redesignated when its parent was moved to a four-lane limited-access expressway that bypassed the towns of Cameron
and Vass
in 2005.
is a short loop route within the town of Stonington
that passes through Stonington borough. US 1 originally went along this route until 1941. US 1A is the only surviving alternate U.S. highway in Connecticut.
The route is 1.93 miles (3.1 km) long and takes the following route: From US 1 to North Water Street, to Trumbull Avenue, to Alpha Avenue, then
to Elm St, and back to US 1.
of Rhode Island
. It serves as a bypass of the downtown areas of Providence
and Pawtucket
, which US 1
goes through. US 1A is a lengthier route than the section of U.S. Route 1
that it bypasses.
US 1A should not be confused with Rhode Island Route 1A. In Rhode Island, US 1A exists in segments between Warwick and Pawtucket. Not helping matters is the presence of incorrect signs on both routes, marking Route 1A as US 1A and US 1A as Route 1A.
US 1A runs for 1.7 miles (2.7 km) through Warwick
along Post Road and Warwick Avenue. Then in Cranston
: it runs for another 1.7 miles (2.7 km) continuing along Warwick Avenue to Norwood Avenue and Narragansett Boulevard before crossing into Providence
. There, the highway continues to follow Narragansett Boulevard and turns along Allens Avenue, Eddy Street, Point Street. US 1A uses the one-way pair
ing of the East Providence Expressway eastbound while the westbound traffic is routed along Water, James, and South Main streets. On the other side of the one-way couplet, the highway continues on the East Providence Expressway into East Providence
. US 1A uses another one-way pairing with the eastbound traffic using the expressway, and Warren and Pawtucket avenues. The opposite direction is routed along Pawtucket and Newport avenues. The last city through which US 1A runs is Pawtucket
where it runs for 2.3 miles (3.7 km) to the Massachusetts
State line at Route 1A
on Newport Avenue.
US 1A was never U.S. Route 1
at any point in time. In Warwick, US 1A used to stay on Post Road east of Route 117
instead of turning north to overlap it. It stayed with Post Road to Pawtuxet Village
, then used Broad Street into Cranston to rejoin the current US 1A alignment at Norwood Avenue.
It now begins at exit 7 on the I-295 freeway (also known as Franklin Street). It travels east along the Franklin Street Arterial until its intersection with Commercial Street and the Maine State Pier. At this point it makes a 90-degree turn onto Commercial Street, which it will follow through the entire waterfront area passing such landmarks as Becky's Diner and the US Customs Service Portland office.
It then passes under the four lane ME 77/Casco Bay Bridge roadway, and then continues along Commercial Street (and the waterfront) until its intersection with Valley Road and the Veteran's Memorial Bridge Road. US 1A follows neither routing but instead turns west and north following the Fore River Parkway where it loops back to meet I-295 again at a complicated single-point urban interchange
(exit 5) which also serves Congress Street (ME 22), where US 1A now terminates.
in Maine
, serving the Bangor
metropolitan area. The route is 50.3 miles long and runs from Stockton Springs
to Ellsworth
.
Route 1A enters Bangor from the southwest by following the west bank of the Penobscot River
through the towns of Winterport
and Hampden. Route 1A crosses the Penobscot Bridge from downtown Bangor into the city of Brewer
, and continues southeast through Holden
and Dedham
to Ellsworth
.
, from Mars Hill
to Van Buren.
Route 1A runs parallel to the Canadian border, as U.S. Route 1
goes through the cities of Presque Isle
and Caribou
. Major towns along US 1A include Fort Fairfield
and Limestone
.
