Project Experience

Strank Memorial Bridge

The bridge was located in Johnstown, Pa and PennDOT District 9 was the owner. The bridge consisted of 9 spans and 8 concrete piers. The 9 spans consisted of 3 Plate Girder Spans, 2 Pre-stressed Concrete Spans, 3 Plate Thru-Girder Spans, and 1 Eleven Panel Steel Truss Span.


8 of the 9 spans and 6 of the concrete piers where demolished in place utilizing multiple pieces of heavy equipment. The equipment included multiple hydraulic excavators, 2-40 ton off road trucks, Cat track loader, Hydraulic Concrete Hammers, Hydraulic Concrete Pulverizer, Second and Third member Shears, and Skidsteers. All of the material generated from the demolition was recycled.


The remaining Steel Truss span was over multiple railroad tracks that carry up to 80 trains per day. The structure was dismantled utilizing temporary support structures. The support structures where needed to be able to cut and remove the truss in pieces and to prevent any uncontrolled collapse. Two Liebherr LTM-1400-7 with MAX-ER cranes where mobilized to perform the removal. The cranes were able to lift a maximum of 500,000 pounds. The truss was picked in two sections. Each section required both cranes on the pick, this was due to the weight of the section and the safety factor required by the railroad. The truss pieces where set in an area away from the tracks and was processed for recycling.
