      History



      What is now I-90 was originally planned as part of the Pennsylvania Turnpike system in the 1950s. With the creation of the Interstate Highway System in 1956, this road was dropped from the turnpike system and would instead be built as a part of I-90. I-90 was completed through Pennsylvania on October 28, 1960. In 2007, a major pileup forced a 15-hour closure of the entire stretch of I-90 in Pennsylvania due to winter storm whiteout conditions.
