Street View, Oct 2018 Note the high-level bridge in the right background. |
Note how the depth of the truss makes the semi-trucks look small.

Phil Martin Photography posted The Emlenton Bridge on I80 sits in three counties Butler, Clarion and Venango County. It’s about 270 feet above the Allegheny River. |

Jackson-Township historical preservation added Keystone Shortway Bridge (I-80), over the Allegheny River at Emlenton, Venango County. This bridge is the highest in the East. This modern super-highway, between Sharon and Stroudsburg, provides the fastest direct route across the state and easy access to many choice recreational areas. [I-80 in Pennsylvania is called the Keystone Shortway.] Ken Rupert shared As a teenager, I saw this bridge being built from the smaller bridge in the background! 🙂My Dad referred to the "Keystone Shortway Bridge" as the "Emlenton High Level Bridge" Was there a name for the smaller bridge other than the "Emlenton bridge" as I remember? Yes, the new I-80 bridge sure saved a Lot of time if you look at the winding roads in the picture! 😉 |

"With a height of 270 feet (82 m) above the river, the Emlenton Bridge was the highest bridge in the Interstate Highway System when completed in 1968." [

Historic Bridges has a lot of bridges in Venango County, but not these two. In fact, there are no bridges over the Allegheny River.
This image would be between 1968 and 1987.

HAER_data The Whipple trusses were made with wrought iron. This bridge was pictured in the 1885 catalog for the builder, the Wrought Iron Bridge Company of Canton, OH. [My first thought is that it should have been saved as a trail bridge. But looking at a map, I guess there is nothing on the south side to walk/bike to. So are there any fish in this river? I guess it was rather high to function as a fishing pier.] |

As expected, the truss was pin connected.
