SR 90: Sierra Vista Multi-Use Path

The purpose of this project is to construct a Multi Use Pathway (MUP) along SR 90 between Fort Huachuca East Gate and North 7th Street in Sierra Vista. NCSG performed field and laboratory investigations, provided earthwork factors, compaction factors, evaluated collapse potential, and provided recommendations for two retaining walls. One of the walls designed involved using a lightweight concrete fill to mitigate global stability.
