Here are photos taken on June 25, 1925 showing the laying of a new forty-two inch sewer line at the intersection of West Liberty Avenue and Saw Mill Run Road, near the entrance to the Liberty Tunnels. The modern sewage line was being laid in preparation for the construction of Saw Mill Run Boulevard, which was planned to begin in 1929. These ongoing modernization projects were essential due to the extensive residential growth of the South Hills area.

The bottom two photos show the staging area for the Kund and Eiben Manufacturing Company. The concrete sewer pipe sections were delivered by rail and lowered along a small incline. Rows of concrete sewer pipes line the open area on the Brookline side of Saw Mill Run Road. The homes along Timberland Avenue and Cadet Avenue are visible in the distance. This is now the location of the Red, White and Blue Thrift Store.
