The Shepard Point Oil Access Project is an ongoing project that will help accelerate response times to oil spills. Hilfiker was chosen to supply the materials to build an access road to the monitoring station, with our contributions including several true bridge abutments with full load capacity, 7 trinity walls, and a boat ramp. 

The walls and abutments varied in size with a max height of 38 feet and a combined 23,477 square feet of materials. 

This project was constructed by Turnagain Construction, designed by Shannon & Wilson and GHD, and is owned by the Native Village of Eyak.

The US-95, WIR Bridge, Deep Creek Bridge project was constructed in 2022 by MA DeAtley Construction.  There is 13,760 Sf of Welded Wire Wall with a max height of 36'. The walls were designed by Shannon and Wilson, owned by Idaho Transportation Dept. and located in Potlatch, ID.

The Santa Clara Divide, CA ERFO FS Angel 2023-1(1) 3N17 wall was built in 2025 to extend the wall constructed in 2020 that suffered an additional failure next to the existing wall.   The additional portion of wall is 3680 SF, with a maximum height of 40' and ties into the existing wall.  The wall extension was built by Stewart Engineering Inc., designed by Cesaretti Engineered Solutions, and owned by Federal Highway, Central Federal Lands.
