Great Bear River Bridge Construction Geotechnical and Granular Materials Investigation. The Project scope is to investigate up to ten (10) prospect material sources for their potential to supply bedrock, aggregates, granular and common fill and to conduct drilling to determine geotechnical conditions in the area of proposed bridge abutments and roadway approaches during the winter and summer of 2019.
