In 2014, Landmark was asked to replace two round culverts, acting as a fish barrier, with a full span open bottom structure on the Pine Creek Tributary (Crossing 3251). The bridge design included Geosynthetic Reinforced Soils (GRS) technology with modified steel sheet pile components to meet industrial loading requirements and a low road profile. Project steps included fish salvage, flow diversion, culvert removal and bridge construction using horizontal steel sheet piling, EPS construction foam as well as fabric and fill. The road was back to full function within 6 days.

Another successful project done in collaboration with Terratech Consulting Ltd.
