National Tube Co. Continental works was consumed by J&L Pittsburgh works. That is old 2nd avenue where the horse carriages are at. the railroad "Y" is a good point of reference. Courtesy of Google Maps 2025 and Historic Aerials 1952.

JONES & LAUGHLIN STEEL MILLS

Pittsburgh, PA

A circa 1906 view of #HistoricHazelwood taken from way up above Swinburne Avenue looking toward the Greenfield Avenue underpass and the Scotch Bottom neighborhood, which was fully engulfed by the National Tube Company's Continental Works along "Old" Second Avenue.

Jones & Laughlin's operations were mainly centered along the river bank and around the Hot Metal Bridge, where iron and coke was made in Hazelwood (the iron side), transported across the Monongahela River to the South Side aka the steel side where it was shaped.

The majority of property pictured here once belonged to Mary Schenley, of Schenley Park, which was just a stone's throw from this spot, beyond Four Mile Run. A railroad switch occurs at Swinburne (formerly known as Sylvan Ave.), separating the Baltimore & Ohio Railroad (B&O) from the Pittsburgh Junction Railroad (at left).

I could not reconcile the curve in the railroad in JaQuay's photo with today's satellite image. This topo explains why. That curve, the upper leg of a wye, no longer exists! In fact, many of the 1951 roads are gone. The building of I-376 changed a lot things in this area. The extant southern leg of the wye can be seen in Andrew's photo at the top of these notes.
