Tapani Inc. was awarded two projects related to the Historic Columbia River Highway (HCRH) State Trail located near Hood River, Ore. For the JB Yeon-Moffett Creek section, Tapani was hired as the prime contractor to construct a bridge over Moffet Creek. The structure was an 80-foot prestressed arch girder bridge with concrete girders designed to replicate the old Moffett Creek bridge located to the east of the project. The substructure included drilled 36-inch shaft footings, architectural face bents and 160 feet of baluster-style bridge railing, also replicating the old arch style architecture of the old bridge. The project also included the construction of approximately 1.5 miles of pedestrian trail, which included an 80-foot pedestrian bridge and 11 retaining walls in six different design types: rockery, gabion, micropile, soil nail, cast-in-place (CIP) cantilever, and mechanically stabilized earth (MSE).
The second HCRH State Trail project awarded to Tapani Inc. was as a subcontractor for the Lindsey Creek to Starvation Creek Trailhead section. This project connected the Gorton Creek Trailhead located at Wyeth to Lindsey Creek. The work on this section consisted of constructing a trail, cast-in-place (CIP) retaining walls and a 50-foot-high prestressed girder bridge for walking, biking and outdoor enthusiasts.
