Pittsburgh in 1910. The Pirates left Exposition Park the year before and immediately won the World Series at the new Forbes Field. The old Union Bridge has been demolished in favor of the new Manchester Bridge, which connects the city to its newly acquired North Side (Allegheny City was annexed in 1908). The new Wabash Bridge spans the Monongahela just up from the Point Bridge. The Wabash was for rail traffic and was built in 1904. It stood until 1948. The city is definitely suffering from the effects of the multitude of steel mills lining the upper Allegheny and Monongahela rivers. It does look like a "smokey city."
