Reinvestment in the Los Alamos Canyon Bridge (LACB) deck, superstructure, and substructure, ensures continued access between Los Alamos National Laboratory (LANL) and the Los Alamos County (LAC) town site; as well as maintains emergency response qualifications to/from the Los Alamos Medical Center (LAMC). The operability of the LACB is critical to the institution and with the evolving oversight from the Federal Highway Administration (FHWA), Department of Energy (DOE) Headquarters, and National Nuclear Security Administration (NNSA); it is imperative safety of the infrastructure is sustained. The Los Alamos Canyon Bridge is 60 plus years old (typical bridge design life of 50 years), a fracture critical structure (no girder redundancies), has an average daily traffic in excess of 13,000 vehicles/day (primary route for LAC commuters), is deteriorating (decreasing code ratings, per inspection), was last rehabilitated in 1992, and maintains access for fire evacuations (Cerro Grande, Las Conchas). Reinvestment in the bridge is expected to extend the service life of the LACB, reduce average maintenance costs by $0.5 M to $2.8M, per year, and provide compliance with current code requirements. Pros, cons, and proposed funding schedule are provided.
