PROJECT

PA DCNR Snowmobile Bridge Tioga State Forest

Project Overview

Areté Structures designed, fabricated and supplied eight unique pedestrian bridges for the Oregon Parks and Recreation Department in the fall of 2018.  These bridges were dark brown in color with FRP decking; varying in length from 25 feet to 55 feet and up to 8 feet wide. This extra width can accommodate trail maintenance vehicles. All bridges kits were bundled together by the Areté team in Boone North Carolina and delivered on one load to Rooster Rock State Park and Sunset Bay State Park in the beautiful state of Oregon.
