ReplacementIn 2012, the Pennsylvania Turnpike Commission set aside nearly $300 million to replace the bridge, and began the design phase of its Milepost 12-14 reconstruction project[4]. The project involves widening of the existing turnpike between the two mileposts to support a total of six 12' wide lanes, two 12' wide shoulders, as well as a 26' wide median. To support a wider road, three overhead structures along the turnpike were replaced between 2015 and 2016, and the ramp bridge over Route 18 at the nearby Beaver Valley Interchange was replaced with a temporary bridge[5]. The interchange itself will also be completely reconfigured and the turnpike's mainline bridge over Route 18 will be replaced.[6] Construction is expected to resume in 2019 to widen the turnpike, replace the bridge, and reconfigure the Beaver Valley Interchange.[7]{{Crossings navbox |structure = Bridges |place = Beaver River |bridge = Beaver River Bridge |bridge signs = {{jct|state=PA|I|76|name1=Pennsylvania Turnpike}} |upstream = Fifth Avenue Bridge |upstream signs = {{jct|state=PA|PA|351}} |downstream = Eastvale Bridge |downstream signs = {{jct|state=PA|PA|588}} }} See also
