Liberty Tunnel
Description
The Liberty Tunnels (also known as the Liberty Tubes) are a pair of tunnels located in Pittsburgh, Pennsylvania that allow motorists to travel between the South Hills of Pittsburgh and the city, through Mt. Washington. The tunnels were vital in the expansion of the South Hills suburbs by providing a direct route to the city, eliminating the time-consuming task of navigating around or over Mt. Washington and its inclines. The tunnel connects the Liberty Bridge & Saw Mill Run Blvd.

- Design
- The tunnels were designed by Amos D. Neeld, who would also supervise the construction of the adjoining Liberty Bridge, which gives travelers a way to cross the Monongahela River after passing through the tunnels. The design was two vertical wall horseshoe profile tunnels, each consisting of two lanes of traffic and a 4 ft (1.2 m) sidewalk. The sidewalks, though minimally used and in disrepair, were removed during a renovation in the 1970s in order to widen and increase the height of the transit lanes.
