The final bridge in our 10-year anniversary look back at the Pittsburgh bridges and their environs is the Hot Metal Bridge. This is upriver from the Birmingham Bridge and the last bridge on the Monongahela before the big bend that hides downtown from view.

The Hot Metal Bridge was built to connect the Jones and Laughlin Steel Mill’s sites on opposite sides of the Monongahela River. With the industrial decline of Pittsburgh’s steelmaking industry in the mid- to late-20th century, Jones and Laughlin’s operations ceased over the 1980s. The first redevelopment of a portion of their property began in 1981. The redevelopment continues today.

On the south side of the river, the former site of milling operations is now the South Side Works shopping, dining, and residential area. Since 2012, the first marina in the city limits was added here and buildings under construction have opened (first photo pair), other buildings not pictured have been added.

On the north side downriver, the former site of the blast furnaces is now the Pittsburgh Technology Park containing office buildings, parking, and a hotel. The hotel was added in the last ten years as well as several other buildings outside the frame in the second and third set of photos.

On the north side upriver, the former Hazelwood Works is now the Hazelwood Green site a planned mixed-use, multi-block redevelopment. The remaining mill buildings on the site have been redeveloped as office and research facilities with the Mill 19 building visible on the left side of the river in the fourth photo pairing. The space between and around these buildings is expected to be filled in with other buildings of a variety of uses in the coming years.

The final photo pair features the former St Josaphat’s Catholic Church on the South Side Slopes, which is a building I have an eye as one of Pittsburgh’s pending adaptively reused religious buildings. This view shows another angle of the growth of the South Side Works development.

While both South Side Works and the Pittsburgh Technology Park were substantially developed by 2012, they continue to expand. On the other hand, Hazelwood Green is just beginning to be developed and is still predominantly vacant land. In another 10 years, perhaps, the upriver view from the Hot Metal Bridge will be significantly altered.
