Construction is complete on the two pedestrian tunnels that now provide safe crossing under State Route 14, approximately twenty-six miles east of Vancouver, Washington. The Cape Horn Trail is a popular 7.5 mile trail with spectacular views of the Columbia River Gorge. GreenWorks, working with Wallis Engineering (civl engineering) and Kramer Gehlen & Associates (structural engineering), provided the design for the stone facing of the tunnel facades and planting design at the tunnels. The stone used on the project is local quarried basalt stone. The tunnel facades were designed to relate to other historic Cascadian examples of stone masonry found within the Columbia River Gorge National Scenic Area. To quote the Washington Trails Association,‘The Cape Horn Trail is about to become one of the prized jewels of the Columbia River Gorge National Scenic Area.’
This WSDOT project, in partnership with the USDA Forest Service was made possible by funding provided by Western Federal Lands Highway Division. The General contractor for the project was Rotschy, Inc and stone masonry work was provided by Custom Masonry, Inc.
