William S. Moorhead Federal Building

The William S. Moorhead Federal Building is a 340 ft-tall skyscraper that is located in downtown Pittsburgh, Pennsylvania, United States. Plans for the building were announced on November 9, 1958, and the structure was completed in 1964.

It has 23 floors and is the 21st tallest building in Pittsburgh.

History
The building, simply known as the Federal Building during its early years, was a $20 million design and construction project that was completed in 1964. It created a centralized home for what had previously been a large number of scattered offices in several different office buildings in Pittsburgh. Designed by Altenhof & Bown, the building replaced an existing Greyhound bus station on the property.

In 1980, the building, which accommodated 35 federal agencies at that time, was renamed the William S. Moorhead Federal Building, in honor of retiring Representative William S. Moorhead. Despite some criticism of the practice of naming buildings after retiring officials, the statute to rename the building was approved on October 9, 1980.

The building currently has 21 tenants, including the Internal Revenue Service, the Veterans Administration, the Army Corps of Engineers (formerly housed in the Manor Building), the Weather Bureau (formerly in the US Post Office and Courthouse), the Federal Bureau of Investigation (formerly in the Union Trust Building) and the Central Intelligence Agency (originally referred to as "Agency 39"), employing 4,000 employees.
