The Parkway East includes the Squirrel Hill Tunnels

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.

Details related to the design and construction of the Squirrel Hill Tunnels includes:

  • Two tubes - 4,225 feet long, 29’-4” wide

  • Design started in 1937

  • Construction began in 1948

  • Opened on June 5, 1953

  • Cost $18 million (largest construction project in Pennsylvania to date at that time.)

Currently, the tunnel is undergoing rehabilitation. The project includes updating the electrical systems, lighting system, control system, ventilation system, structural repairs to the walls and arched ceiling, installation of a water line and other improvements.
