Street View, it is too bad the driver wasn't going in the other direction so that it was in the closer lane. |

This is an example "of an exceedingly rare variety of arch bridge, that of a crescent arch. The design of a crescent arch is that of an arch which begins as a solid rib, which splits apart and becomes a braced rib in the middle of the span." [HistoricBridges-vehicle]

This is another example in Pennsylvania of where the space is so narrow between the river and the hills that they built the turnout for a branch on the bridge.

William Novak commented on Jeffery's post Look out below! (From the Pittsburgh Tribune Review, June 8, 2014. On CSX.) [Looking at street views, there was a road under that part of the bridge.] |
"This bridge was built in 1968 and is an extremely late example of a truss bridge that uses rivets in its construction. Specifically, rivets are used in the built-up members. Connections are bolted. The lack of v-lacing and lattice in all built-up members is also typical for this late era in riveted built-up beams. Approach spans are welded girders, with no rivets." [HistoricBridges-railroad] It struct me that, because of the nearby road bridge, I can get a closeup of the members. I can clearly see where bolts were used to fasten the members, but I can't see where rivets were used to build the members.
