History: The only Interstate business route that originates from Interstate 376 for its entire length, and the only three-digit one located within the Commonwealth of Pennsylvania and the first in the Northeast since Interstate Business Spur 495 in Massachusetts was decommissioned.

Signed in 2009 when the Interstate 376 designation was extended to Sharon and supplanted the PA 60 designation.

Due to construction of the US Airways flight operations center and development along Cherrington Parkway, the Ewing Road interchange needed an upgrade to facilitate the increased traffic.  The first phase was installing new traffic signals and expansion of the eastern side of the interchange.  A roundabout, the first to be built in Allegheny County in years, was selected as the remedy for the western side of the interchange.  On June 27, 2011 at 11 AM, the eastbound on-/off- ramps closed for construction and reopened on October 31 when the $950,000 project was completed.
