PA Turnpike Northeast Extension Bridge NB 751

Wagman’s Geotechnical Construction Group was contracted with Susquehanna Valley Construction Corporation (SVCC), to furnish and install temporary excavation support (TES) and micropiles for abutment support of a new bridge. This new bridge will carry I-476 over Edella Road in South Abington Township, Lackawanna County, Pa.

The TES, which included tiebacks due to the cut height, was provided to facilitate phased replacement of the bridge. Wagman utilized micropile soldier piles, drilled into the bedrock below the bridge. This was a design-build aspect of the project, where Wagman provided the engineering of the TES, as well as installation.

There were 246 production micropiles – battered and vertical – for a total of approximately 17,000 linear feet. Two verification tests were performed as well as six proof tests.
