Cape Horn Trail is an eight mile trail in Skamania County located twenty six miles east of Vancouver, WA to which the Forest Service is currently making improvements. The existing trail has two at grade crossings where hikers and horse back riders traverse heavily traveled State Route 14. To improve safety for trail users, the Forest Service and WASH DOT are constructing pedestrian underpass tunnels at these two crossings. GreenWorks’ role in the project was to develop schematic designs for the tunnel entrances and provide construction design drawings for the tunnel fascias, which included stone wall construction, custom metal guardrail fence design and planting design around the entrances. The design of the tunnel fascias uses locally quarried Columbia River Basalt to form walls that are in accord with other examples of historic basalt stone work in the Columbia Gorge.
