Replace Spillway Catwalk and add Trunnion Pin Access

Location: Marion County, Arkansas
Completed: 2009
Owner: USACE – Little Rock District

The design-build project at Bull Shoals Dam consisted of design, fabrication and installation of catwalks around the existing operating machinery and spanning from pier to pier. The new catwalks replaced the old and deteriorated catwalks in place at the onset of the project. New access ladders were also designed, fabricated and installed so that maintenance and inspection activities could be performed on the downstream area of the gates and the trunnion arms.
