San Engineering Structural Projects

Blue River Pedestrian Bridge. Silverthorne, Colorado - San Engineering performed the structural design of a 210 feet single span pedestrian bridge over the the Blue River. A floodplain study and utility design for a public restroom were also part of this project.

San Engineering performed design of a triple-cell precast culvert bridge over the overflow channel of the South Platte River. The bridge, intended to be a centerpiece for a new development, included a number of detailed architectural enhancements including ornamental railings, architectural concrete pillars, and decorative lighting.

San Engineering performed the design of a new 9-span, 1250-foot long bridge carrying the extension of 35th Avenue over the South Platte River floodplain. The project included the completion of an exhaustive alternatives analysis study in order to identify the most economical structure type and span arrangement.

San Engineering is responsible for the design of a new bridge replacing a structurally-deficient bridge in Fountain, Colorado. The existing 3-span bridge will be replaced with a single-span prestressed concrete girder structure on driven steel pile foundations. The new roadway profile will be raised by approximately 2’-0”, to allow for 100-year flows to pass unimpeded.

San Engineering performed Civil and Structural Engineering for Phase III of the Plum Creek Trail for the Town of Castle Rock. The project included an evaluation of “bridge versus box culvert” for a crossing of Sellars Gulch, east of the confluence with East Plum Creek. The project also included the design of over 20 retaining walls. The wall types varied depending on location and application. Retaining walls included Mechanically-Stabilized Earth (MSE) as well as cast-in-place concrete.
