Washington State Route 110: State Route 110 (SR 110) is a 11.10 mi state highway serving Olympic National Park and the Quileute Indian Reservation within Clallam County, located in the U.S. state of Washington.  The highway travels west from U.S. Route 101 (US 101) in Forks as La Push Road along the Quileute and Sol Duc rivers to the boundary of Olympic National Park east of La Push.  La Push Road was originally added to the state highway system in 1937 as Secondary State Highway 9B (SSH 9B), but was removed in 1955.  SR 110 was later established on the route in 1991 after a previous highway with the same designation was removed.  A spur route extending west to Mora was originally added with SSH 9B and re-added with SR 110 in 1991.

New York State Route 9B: New York State Route 9B (NY 9B) is a state highway located within Clinton County, New York, in the United States.  The route serves as a connector between its parent route, U.S. Route 9 (US 9), in the town of Champlain and US 11 in the village of Rouses Point.  While US 9 bypasses Rouses Point to the west, NY 9B veers east to serve the village and the shoreline of Lake Champlain.  NY 9B is the northernmost section of the Lakes to Locks Passage, an All-American Road.  Modern NY 9B was the original alignment of US 9 through the town of Champlain.  US 9 was moved onto its present alignment west of Rouses Point in the mid-1940s, at which time its former routing to Rouses Point became NY 9B.

Virginia State Route 9: State Route 9 (SR 9) is a primary state highway in the U.S. state of Virginia.  Known as Charles Town Pike, the state highway runs 13.08 mi from the West Virginia state line near Mechanicsville, where the highway continues west as West Virginia Route 9 (WV 9), east to SR 7 and SR 7 Business in Paeonian Springs.  SR 9 is the main east–west highway of northwestern Loudoun County, connecting Leesburg with Hillsboro and the West Virginia cities of Charles Town and Martinsburg.  As a result, the state highway and its West Virginia continuation are a major, overburdened commuter route between the Eastern Panhandle of West Virginia and Washington, D.C..

Washington State Route 92: State Route 92 (SR 92, commonly called the Granite Falls Highway) is a short 8.25 mi long Washington state highway entirely in Snohomish County.  The roadway connects SR 9 north of Lake Stevens' Frontier Village district to the Mountain Loop Highway in Granite Falls, serving as the primary connector to Granite Falls.  The first form of transport to use the current route was the Monte Cristo and Everett Railroad, which roughly followed the current roadway.  In 1937, Secondary State Highway 15A (SSH 15A) was established on a route from Primary State Highway 15 (PSH 15) / U.S. Route 2 (US 2) northeast to a concurrency with SSH 1A then east to Granite Falls.  Later in 1964, SSH 15A became SR 204 , SR 9 and SR 92.  Recently, the Washington State Department of Transportation (WSDOT) has completed small projects to improve SR 92, including two roundabouts within the first two miles of the highway's western terminus and a roundabout/truck bypass of Granite Falls.

Washington State Route 524: State Route 524 (SR 524) is a 14.56 mi long state highway in the U.S. state of Washington, located entirely within Snohomish County and serving Edmonds, Lynnwood, Bothell and Maltby.  The roadway begins at SR 104 in Edmonds and travels east past SR 99 , Interstate 5 (I-5), under I-405 , past SR 527 and SR 9 to end at SR 522 in Maltby.  The road also has two spur routes, one connecting to SR 104 in Edmonds and another connecting to I-5 in Lynnwood.  First appearing on a map in 1895, the highway was designated as part of Secondary State Highway 1W (SSH 1W) in 1957 during an extension from Edmonds to Lynnwood.  SSH 1W was extended further to SSH 2J (present-day SR 527) in 1959 before becoming SR 524 in 1964.  A final extension east to SR 522 was completed in 1991.

NY 456 was assigned in the early 1970s and is maintained by the Clinton County Highway Department as County Route 58 (CR 58).  The route was decommissioned on March 18, 2015.

New Jersey Route 67: Route 67 is a short state highway entirely within the community of Fort Lee in Bergen County, New Jersey.  It is part of the original alignment of U.S. Route 9W.  The road runs 1.86 mi from an intersection with Central Boulevard in Fort Lee (also designated as Route 5) down Palisade Avenue in downtown Fort Lee.  There it becomes known as Lemoine Avenue, terminating at an interchange with U.S. Route 9W, the Palisades Interstate Parkway and New Jersey Route 445S in Fort Lee.  The route was designated originally as a portion of State Highway Route 18N in 1923, and was split up in 1929 as part of current-days New Jersey Route 63, U.S. Route 9W and Route 67 for Routes S-1, 1 and Route S1A.  Route S-1-A remained intact on Palisades and Lemoine Avenue until the 1953 state highway renumbering when it was switched over to Route 67.  The route has remained virtually intact since.
