The George D. Stuart Bridge was built in 1952 across the Allegheny River.  On the right, it's seen in a Google Earth image.  As you can tell from the bridge's shadow, it's considerably higher on the near side (the bluffs of New Kensington, elevation 925 feet) than on the far side (the flats of Tarentum, elevation 748 feet). I moved to this area in 1980, before the bridge deck was widened to four lanes.  That first December, a snowstorm during the evening rush hour tied up traffic for hours.  Cars with rear-wheel drive had great difficulty making it up the long icy slope.  Fortunately, I haven't encountered that situation since. Below is a panorama I shot from the bridge the following autumn, October 1981.
