In 2001, the Pennsylvania Turnpike was in the design phase for widening the roadway and flattening a curve on the east side of the double tunnels, the Kittatinny and Blue Mountain Tunnels, so we surveyed to establish the alignment of the tunnels (there is a slight curve on the east side). So, over two days the PTC shut down one side, then the other, while we traversed through. Being the end of March and warming up outside, this place was a proverbial wind tunnel. The PTC also took advantage of the closure and to perform some maintenance. #surveylife
