Description 

It is significant as a rare surviving example of a long, multiple-span metal truss bridge. Built as a toll bridge to carry vehicular, pedestrian, and trolley traffic across the Monongahela River, the bridge improved regional transportation and contributed toward the economic development of Monongahela River valley towns. Construction of a bridge across the Monongahela River at North Charleroi surmounted a formidable natural barrier and completed a regional street railroad transportation network that stretched from urban Pittsburgh to developing Westmoreland County.

Here is an article that explains some of the issues that the contractor has run into with the reconstruction project.

The new bridge will be a haunched steel girder design, similar to the Veterans Bridge in Downtown Pittsburgh. All of the piers have been replaced and use formliners to simulate textured stone.

High quality picture of the new bridge under construction:

Came across a news article about the bridge, it was closed last month due to structural problems, and now it appears this bridge's fate is in question.

And here's historicbridges.org's website on the bridge, with pictures.
