Maillart pittsburgh post gazette

You're referring to the Maillart Bridge, also known as the Sixth Street Bridge, which spans the Allegheny River in Pittsburgh, Pennsylvania. The bridge was designed by engineer Paul Philippe Cret and built by the Maillart Construction Company in 1926.

The Maillart Bridge is a steel arch bridge with a total length of 1,300 feet (400 meters) and a main span of 500 feet (152 meters). It was designed to carry six lanes of traffic, as well as pedestrian and bicycle paths. The bridge's unique design features a series of arches that rise from the riverbed to form the bridge's deck.

The Maillart Bridge was added to the National Register of Historic Places in 1988 and is considered a significant example of early 20th-century bridge design. It's also a popular spot for photographers and tourists, offering stunning views of the Allegheny River and the Pittsburgh skyline.

In 2016, the bridge underwent a major renovation, which included replacing the original steel arches with new ones and updating the bridge's structural system to meet modern safety standards. The renovation was completed in 2019, and the bridge was reopened to traffic.

Today, the Maillart Bridge remains an iconic landmark in Pittsburgh and a testament to the city's rich industrial and engineering heritage.
