36" Mountain Pass

Rogers Pass, Montana

Allied installed a 36” liner at Rogers Pass, Montana right after the first winter snow hit.  To start the project off Allied had to work with bypassing a creek that was running through the culvert. The line included a 22-degree angle change. Due to the location of the pipe heavy equipment was needed to position the liner to allow for a smoother pull-in process.
