has been a rather free-flowing double trumpet, grade separated interchange
between the two freeways. But for the first 23 years of the turnpike,
this interchange was vastly different. It was the only non-trumpet
interchange within the system (excluding termini points) and featured very
tricky and gridlock causing left turns within the interchange. (See
image on right). With the birth of the Interstate Highway System
in the mid-1950s, new freeways were built and in many cases the turnpike
kept the original interchange using local roads to connect to the new freeways.
Interchanges with what would become I-81, I-176, I-80, I-70 in Breezewood,
and I-79 were left with the original design.
Meanwhile in the 1950's, the state began building a freeway that ran from New Stanton west towards Washington. This freeway, signed PA 71, was to connect those in the industrial Mon Valley to the Turnpike. Opened to the Turnpike by 1959, the amount of traffic using this interchange increased substantially. It was in October of 1963 that the PTC began a construction project that would cost $1.6 million to completely replace the interchange. A little over a year later on November 12, 1964, the new New Stanton interchange officially opened to traffic. (1) This was the first turnpike interchange to be completely replaced, and it also was the first interchange that was reconfigured to provide direct Interstate-to-Interstate traffic.
