R&M provided surveying and mapping, geotechnical investigations and recommendations, hydrologic and hydraulic analysis, NEPA document preparation, civil engineering and permitting in support of a two-phase design of 2.5 miles of new and reconstructed roadway, including a new 440’ long three-span bridge over Wood River near its outlet into Lake Aleknagik.
The project site is rich in wildlife and archeological history. As the design progressed, R&M made modifications to minimize impacts to wildlife and cultural resources. We worked closely with the DOT&PF Bridge Section to optimize the vertical alignment that changed the bridge slope to minimize fill encroachment into the river bed and reduce the height of the drill shaft and abutment on the weaker foundation end of the bridge.
The bridge connects the entire community of Aleknagik, previously divided by the Wood River, to the existing roadway system and educational, commercial and travel resources in Dillingham. Prior to its construction, the community relied on boats and snow machines to travel within the area.
