New Name for the Rochester-Monaca Bridge


The Monaca-Rochester Bridge has been renamed to the Rochester-Monaca Bridge.

The name of the bridge is decided each year by the winner of the Rochester and Monaca football game.

The bridge is a continuous cantilever truss that opened in 1986. Like the nearby Vanport Bridge, the top chord is flat and the bottom chord curves downward to form points over intermediate piers. The bridge replaced an unusual three-tower cantilever similar to the Ambridge-Aliquippa Bridge. That bridge, built in 1930, replaced a suspension bridge similar to the 1905 Newell Bridge, located just over the Ohio/West Virginia Border. The Rochester-Monaca Bridge is one of the few major modern truss bridges in Pennsylvania.

Larman Mill Road Bridge Collapses



















On October 31, 2009, a propane truck driver disobeyed the 5 ton posting and crossed the Larman Mill Road Bridge. Engineers post weight limits for good reason. Not surprisingly, the truck (as well as the bridge) ended up in the creek. The Larman Mill Road Bridge served a lightly traveled gravel road, used by only 25 vehicles per day. The Pennsylvania Historic Bridge Inventory attributed the bridge to the Farris Engineering Company of Pittsburgh since it is similar to another bridge, a now-demolished SR 3003 bridge over the same creek. At the time of the PAHBI in 1997, PennDOT owned 6 pony truss bridges in Fayette County. In less than ten years, ALL were demolished. In 2009, the similar county-owned bridge was demolished due to a lawbreaking truck. Given the low use of the bridge, it is unlikely that a new bridge will be built in its place.

The new Point Marion Bridge opened, and the old Albert Gallatin Memorial Bridge bridge was closed to traffic on October 22.

Visit the historic Point Marion Bridge (Albert Gallatin Memorial Bridge) while you can! The National Register Listed Bridge closed to traffic on October 22nd and is to be demolished November 9th. The 1930 bridge is the third oldest thru cantilever bridge in the state! Note that the replacement bridge, a single span Parker truss, has an extra-wide sidewalk to carry a trail.

The Point Marion Bridge carried PA 88 over the Monongahela River between Fayette and Greene counties.

The Pittsburgh Post-Gazette wrote this article about the bridge:
