A study was conducted to investigate short span innovative bridge elements and systems that are suitable to implement at the local government level in South Dakota. Through extensive literature review of research articles, reports, and existing practices within and outside South Dakota, a comprehensive list of short span innovative bridge elements and systems that are suitable to implement at the local government level has been established. The list was converted into a catalog and divided into techniques, superstructures, substructures, materials, and entire bridge structures. The techniques include using prefabricated bridge elements and systems (PBES) and the jointless bridge. Emphasis was maximum economy with mass-production of prefabricated components. The superstructures include the precast inverted tee beam, precast prestressed adjacent box beam, precast prestressed adjacent deck slab beam, precast double tee beam/the NEXT beam, precast modified beam-in-slab bridge (PMBISB) system, the ultra-high performance concrete (UHPC) waffle bridge deck panel, the precast decked bulb tee beam, used railroad flatcars, wide-flange steel beams, and channel beams placed adjacent to each another. The substructures include the geosynthetic reinforced soil (GRS) abutment, mechanically stabilized earth (MSE) walls with single line pile abutments, and the sheet pile abutment. The materials include UHPC, high performance/high strength lightweight concrete, self-consolidating concrete (SCC), expanded polystyrene (EPS) geofoam, cellular confinement system (CCS), and carbon fiber prestressing strands. The xii entire-bridge-structures include the large precast box culvert and the precast three-sided frame. An estimate of cost was developed for the alternatives listed in the catalog. The cost for each alternative provides a somewhat reliable representation of the average cost of the item per square foot of deck, and was obtained from the literature and state Department of Transportation websites. A list of administrative requirements on local bridge replacements without South Dakota Department of Transportation (SDDOT) or federal assistance was compiled and included in this report. Grant County has already conducted several local bridge replacements without federal assistance and it was therefore one of the sources of information on administrative requirements on local bridge replacements without SDDOT or federal assistance. An evaluation procedure with simple inputs for use by local government decision making was developed. It is the intent that this checklist will lead decision makers through the process of cost and performance evaluation, and finally recommend if the project should be completed locally or using a federal program.
