Chrome aerial photograph postcard of the Pennsylvania Turnpike crossing the Allegheny River at the Allegheny Valley Interchange, viewed looking upstream (northeast) from a low-altitude aircraft. Two parallel truss bridges span the river — the railroad bridge in the background and the Turnpike highway bridge in the foreground — with a small wooded island in the river between them and a barge visible upstream. The town of Cheswick is visible on the left bank, with autumn foliage covering the steep valley sides in deep orange. Reproduced from 35mm transparency; color by Pennsylvania Turnpike Commission. Published by Imperial Greeting Card Co., Pittsburgh; printed by Plastichrome/Colourpicture Publishers, Boston.
