The CSVT River Bridge near Harrisburg, Pennsylvania, was a complex civil engineering project where Pittsburghs Tunstall Engineering applied their expertise to steel erectiin, spreader beams, and more.
CSVT River Bridge
Steel Girder Erection Plan / Pier Form Falsework Temporary Towers / Slope Stability Analysis Support of Excavation / Work Platforms / Spreader Beams

TEG provided a wide variety of services for the CSVT project. Most our involvement was on the CSVT River Bridge, which is a 15 span 4545’ long steel multi-girder bridge over the Susquehanna River in Union/Northumberland Counties north of Harrisburg, PA. TEG provided Century Steel with the steel girder erection plans and calculations. With pier heights near 200’ and spans as long as 350’, the erection required multiple finite element models to verify stability, stresses, and to design temporary lateral bracing. Towers up to 85’ tall, Work Platforms, and Spreader Beams were also designed for the project.
