Trenton Dam Concrete & Steel Repair

Trenton, Nebraska


This project was located on the Swanson Lake Reservoir near Trenton, NE. The contract included structural concrete repair, new steel deck drain extensions, structural backfill repair of eroded dike, replacement of concrete gutter system and installation of HDPE liner system with gravel surfacing.


The highway over the dam was closed and traffic detoured during construction.

Within days of starting the project we discovered the structure supporting the bridge required more extensive repair than anyone had anticipated. We engineered a support system and were able to perform the repairs without lifting the bridge.
