For the most part, the U.S. Routes were the primary means of inter-city vehicle travel; the main exceptions were toll roads such as the Pennsylvania Turnpike and parkway routes such as the Merritt Parkway.
Exit the parkway at Route 301 in Putnam County and follow the route west as it meanders through portions of Clarence Fahnestock Memorial State Park, crossing the Appalachian Trail and ambling by a picturesque lake and marshlands.
The first Metro staff survey and feasibility study of the parkway's route was approved in late 1953, before the Metro government itself came into being in 1954.
Pick up DuPont Parkway and continue on the parkway to Delaware Route 1 South.
If completed, the parkway would connect Route 46 to Interstate 280, easing congestion and speeding the commute for those who work in the area's suburban office parks.
Construction of a segment in North Carolina began in 1912 but ceased after the start of World War I (a short stretch of the present-day parkway follows that route near Linville Falls).
Before the parkway was completed, the route that was open to traffic was called Bypass US 20.
The main line of the parkway is designated as Route 445 in New Jersey and NY 987C in New York.
Route 4 Parkway was planned in 1946 as a north south parkway running from Cape May north to Route 6 (now U.S. Route 46) in Clifton, bridging the gap that existed along Route 4 between Rahway and Paterson; this proposal became Route 444 (Garden State Parkway).
