Pennsylvania Turnpike
Bedford Township, Bedford County, Pennsylvania
Marker Inscription
This is one of the original service plazas for the nation's first long-distance superhighway. On October 1, 1940, the Turnpike opened, stretching 160 miles from Irwin to Carlisle. The Turnpike Commission had been created in 1937; construction utilized the old South Pennsylvania Railroad's right-of-way and tunnels. By 1957 the Turnpike spanned 360 miles across the State and extended 110 miles north to Scranton.
Erected by Pennsylvania Historical and Museum Commission
The Story
The Pennsylvania Turnpike opened on October 1, 1940, a 160-mile run from Irwin to Carlisle that introduced Americans to the limited-access superhighway. Built along the right-of-way and tunnels of the unfinished South Pennsylvania Railroad and overseen by a commission created in 1937, it dispensed with intersections and traffic signals entirely. Service plazas such as this one kept motorists moving, and by 1957 the road reached 360 miles across the state with a 110-mile extension toward Scranton.
Why it matters
The turnpike pioneered the design and operation of the modern American superhighway, setting the template for the Interstate era that followed.
The story behind this marker
AI contextThe era
The Pennsylvania Turnpike opened on October 1, 1940, at a hinge point in American history — the Depression easing, war darkening the horizon in Europe, and the automobile firmly established as the way Americans wanted to move. Yet the roads of the day were mostly two-lane routes that ran through the center of every town, choked with intersections, signals, and local traffic. Long trips were slow, and mountain crossings were slower still.
Nowhere was that clearer than in Pennsylvania, where the long parallel ridges of the Alleghenies stood squarely across any east-west journey. Getting a car over those mountains meant steep climbs and sharp curves that punished engines and nerves alike. The marker records that a Turnpike Commission was created in 1937 to confront this obstacle with a genuinely new kind of road.
What they proposed had no real precedent in the country: a long-distance, limited-access superhighway with no cross traffic and no traffic lights, engineered for sustained speed. This service plaza, one of the originals, was part of that plan from the beginning.
People & events
The engineers found their path in an unlikely place — the past. As the marker explains, construction used the old South Pennsylvania Railroad's right-of-way and its tunnels, the remains of an unfinished rail project whose graded route and mountain bores had been sitting unused. Repurposing that abandoned line gave the new highway a ready-made way through the ridges.
When it opened, the road ran 160 miles from Irwin to Carlisle, and it delivered an experience no American driver had had before: a highway free of intersections and stoplights, with lanes and grades built for moving quickly and safely over long distances.
Because the highway was limited-access, travelers could not duck into a nearby town for gas or a sandwich — so the road provided for them directly. Service plazas such as this one kept motorists fueled, fed, and rested without breaking their journey. The marker follows the road's expansion as well: by 1957 the Turnpike reached 360 miles across the state and extended 110 miles northward toward Scranton.
Its place in the American story
As the nation's first long-distance superhighway, the Pennsylvania Turnpike did more than shorten one trip across one state — it demonstrated a whole new way to build and use roads. Here was proof that a limited-access highway could carry traffic faster and more safely over great distances, and that Americans would embrace it.
The features that startled drivers in 1940 — no intersections, no signals, divided lanes, roadside plazas, tunnels punched clean through the mountains — became the standard grammar of modern highway design. The Interstate system that transformed the country in later decades was built on principles the Turnpike put to the test first.
The payoff was enormous. Distance shrank, freight moved more cheaply, and the family road trip became a national pastime. The plaza where you are standing is a modest but real piece of the model that reshaped how America travels, ships, and lives.
If you visit
You have pulled into one of the Turnpike's original service plazas — the prototype for a fixture you now find on every long highway in the country. Notice how everything you need is here beside the road itself: this keep-moving design was a genuine innovation in 1940, born of the highway's promise of an uninterrupted drive.
Take in the Bedford County landscape while you are here. The ridges rising around you are exactly the barrier the Turnpike was built to defeat, and the road's tunnels and easy grades are the answer to them. It is a fine place to appreciate how much engineering it took to make crossing these mountains feel effortless.
If the Turnpike is your route today, let this stop remind you what you are actually driving on — the direct ancestor of the Interstates. Read the marker, take a breath of mountain air, and imagine the excitement of 1940 travelers gliding across Pennsylvania without a single stop sign in their way.

Pennsylvania Turnpike
Bedford Township, PA · est. 1990
When the Pennsylvania Turnpike opened on October 1, 1940, running 160 miles from Irwin to Carlisle, drivers experienced something America had never seen: a long-distance, limited-access superhighway with no cross traffic and no stoplights. Engineers routed it along the abandoned grade and tunnels of the never-finished South Pennsylvania Railroad, and service plazas like this one let travelers fuel up and rest without leaving the road. By 1957 the turnpike stretched 360 miles across the state with a spur reaching toward Scranton.
Fraser Tavern
Bedford, PA · est. 1952
As General Forbes's army pushed toward the Ohio in 1758, frontier settlements sprang up in its wake. Here John Fraser and his wife established an inn and trading post that same year, feeding officers at nearby Fort Raystown, the outpost that grew into Bedford. Fraser was no ordinary tavernkeeper—he had served as a guide and interpreter for a young Colonel George Washington in the tense years before the war.
Forbes Road, 1758, Fort Bedford to Fort Duquesne - Fort Bedford-Raystown (PLAQUE)
Bedford, PA · est. 1930
Fort Bedford, built at the frontier settlement of Raystown, served as the great supply depot and mustering ground for General John Forbes' 1758 campaign against Fort Duquesne. Here an army of nearly eight thousand men gathered before setting out westward toward the forks of the Ohio. The fort anchored the eastern end of the road that still bears Forbes' name.
Bedford County
Bedford, PA · est. 1982
One of Pennsylvania's oldest western counties, Bedford was formed in 1771 and once stretched across much of the state's frontier. In 1758, during the French and Indian War, Fort Bedford rose here as a key link in the British campaign against the French, and the Forbes Road was cut through the wilderness to reach the Ohio country. That military road became one of the great early highways carrying settlers and commerce west.
