Pioneer Avenue and West
Liberty Avenue - 1915
Then and Now
The intersection of Pioneer Avenue and West Liberty Avenue in July 1915 during the refurbishment of the old railroad tressel. Even back then it was considered old, having served the old Castle Shannon Railway for years. West Liberty Avenue was being widened and the new cement support was built to eliminate the metal supports.
The same location in October, 1915 as construction neared completion.
The intersection of Pioneer Avenue and West Liberty Avenue in September 2004 during a normal Wednesday morning. Traffic heading to and from downtown through the Liberty Tunnels makes this one of Pittsburgh's busiest intersections with over 80,000 vehicles per day. It's a far cry from the by-gone days of yesteryear. The old Norfolk and Western railway tressel is going on 100 years old. The Liberty Tunnels appeared in 1924 and are approaching ninety years of service. Above the railway tressel is one of the bridges on the Port Authority South busway. A new interchange was built at the corner of West Liberty and Saw Mill Run before the entrance to the tunnels, partially visible under the railway tressel.
