This project entails the replacement of the timber and concrete bridge built in 1936 that carries Old Highway 99 North over the primary line of BNSF Railway. The new 1,183 foot long bridge is a three-span prestressed concrete girder system with structural earth walls. Additional construction included curb and gutter, sidewalks, a stormwater system and site work.
GeoTest provided materials testing services throughout site preparation and construction. These services included monitoring of imported structural fill and testing of concrete for deep foundations and bridge components.
