Main article: U.S. Route 1A (Wake Forest–Youngsville, North Carolina)

U.S. Highway 1A
Location	Wake Forest–Youngsville, NC
Length	9.0 mi (14.5 km)
Existed	1953–present

U.S. Route 1A (US 1A) is a 9.0-mile (14.5 km) alternate route of US 1 through the towns of Wake Forest and Youngsville, North Carolina. While serving the downtown areas of both towns, the highway bypasses the primary commercial district of each. US  1A runs concurrently with NC 98 Business along South Avenue in Wake Forest and NC 96 in Youngsville. US 1A was established in 1953 when US 1 was rerouted to bypass west of Wake Forest and Youngsville. The former alignment of US 1 became US 1A.

Location	Franklinton, NC
Length	2.7 mi (4.3 km)

Rhode Island

Not to be confused with Rhode Island Route 1A.

U.S. Route 1A
Location	Warwick–Pawtucket
Length	15.2 mi (24.5 km)

U.S. Route 1A is a numbered U.S. Highway running 14.4 miles (23.2 km) in the U.S. state 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 two segments in Providence County connected by a mostly-unsigned concurrency with I-195, while Route 1A serves as a scenic alternate route of US 1 in Washington County. Not helping matters is the presence of Route 1A shields on US 1A.

Route description

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 is not signed at all in Providence, but in all likelihood (judging from the mistakenly placed RI 1A road signs), from Point Street, US 1A uses Water Street to enter I-95 EB at Exit 1D. Similarly, US 1A SB probably exits I-195 WB at Exit 1C onto S Main St, and turns left onto Point Street. The highway continues on the East Providence Expressway (I-195) 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 (114) 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 in Attleboro, traveling concurrently with Route 1A on Newport Avenue to U.S. Route 1.

History

US 1A is not a former alignment of US 1. In Warwick, US 1A formerly ran further north along Post Road east of Route 117 instead of turning north to overlap with the state road. It stayed with Post Road through Pawtuxet Village, then traveled north into Cranston on Broad Street to rejoin the current alignment at Norwood Avenue.

The southernmost section of the route, which exists on Post Road, was part of the Boston Post Road, a former mail route.

Maine

York

U.S. Route 1A
Location	York, Maine

This US 1A segment in York travels along the coast and serves the areas of York Harbor, York Beach and Cape Neddick. The length of this segment is 7.0 miles.

Portland

U.S. Route 1A
Location	Portland, Maine

In Portland, Maine's largest city, the original routing of what was US 1A has largely been eliminated but a short section still exists mainly along Portland's waterfront. 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 Street 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 the exit 5 interchange, which also serves Congress Street (ME 22).

Rockland

U.S. Route 1A
Location	Rockland, Maine

US Route 1A in Rockland bypasses the downtown area and begins at the intersection of Camden and Maverick Streets. Traveling westbound along Maverick Street, it passes Rockland Plaza (which is Rockland's second shopping center), and is concurrent with Maine 17 along this section. It then takes a 90 degree turn at a flashing yellow blinker light to turn left (south) onto Birch Street where it meets North Main Street (which was the former alignment of Maine 17) at a traffic light. US 1A then continues along Broadway, passing Oceanside High School as it continues south through the residential heart of Rockland, and encounters additional traffic lights at Rankin and Limerock Streets, until its end at a traffic light at Park Street where it rejoins US 1.

Bangor

U.S. Route 1A
Location	Stockton Springs, Maine-Ellsworth, Maine

US 1A in Bangor is a loop route off U.S. Route 1 in Maine, serving the Bangor metropolitan area. The route is 54.0 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 Joshua Chamberlain Bridge from downtown Bangor into the city of Brewer, and continues southeast through Holden and Dedham to Ellsworth. This route follows the former alignment of US 1, prior to US 1's relocation after construction of the Waldo-Hancock Bridge. Route 1A signage on this portion lacks directional indicators.

Milbridge

U.S. Route 1A
Location	Milbridge, Maine

In Milbridge, US 1A provides a more direct route for through travelers, as it branches off from US 1 just north of the main business section of the small town of Milbridge, and is known as Bridge St. It then crosses the Narraguagus River and continues in a northeasterly direction whereas US 1 takes a route that is north/northwest to meet Cherryfield before turning back east while 1A takes the more direct (and southern) route closer to the coast to rejoin its parent just east of Harrington. The length of this segment is 7.8 miles.

Whitneyville

U.S. Route 1A
Location	Whitneyville, Maine

This section of US 1A runs 8.1 miles between Jonesboro and Machias via the village of Whitneyville.
