The Squirrel Hill neighborhood provided a challenge during the construction of the Parkway East with its location directly in the path of the roadway. Instead of removing a large apartment complex, a church and a school, a tunnel was suggested. The contract was the largest ever awarded in 1948. As an integral component, the Squirrel Hill Tunnel is considered a contributing element to the historic nature of the Parkway East.
