Construction is commencing on a 4.4km stretch of the Southern Beltway in the US state of Pennsylvania. This forms part of a project for a 21km section of toll road, with its completion expected in 2022. The entire project is for the extension of the Southern Beltway from the Turnpike 576 terminus at US Route 22 in Robinson Township, to a new interchange with Interstate 79 at the Allegheny-Washington County line. The work is needed to boost capacity and improve transport, while cutting congestion for drivers in the area. The project provides an extension for the existing stretch of Beltway connecting Pittsburgh International Airport and US 22 to Interstate 79.
The work has been split into nine sections for the construction process. Two are complete and work is underway on another four. The project includes building an overpass and three smaller bridges, as well as a 420m bridge with five spans.
