Asset Management Plan for the Ambassador Bridge
Notice bibliographique
Résumé
Opened to traffic on November 15, 1929, the Ambassador Bridge is an international crossing spanning the Detroit River between Detroit, Michigan, and Windsor, Ontario, Canada. At that time, the bridge’s 1,850-ft suspended span was the longest of any bridge in the world. It is owned, operated, and maintained by the Detroit International Bridge Company (DIBC). It is the number one U.S.–Canadian commercial crossing in terms of trade volume, carrying 23% of all surface trade between the two countries. The Michigan Department of Transportation (MDOT), with the support of FHWA and cooperation from DIBC and other local stakeholders, has broken ground on the largest single construction contract that MDOT has ever undertaken, the $170 million Ambassador Bridge Gateway Project (ABGP). The ABGP is a major freeway reconstruction effort that will enhance commercial access to the Ambassador Bridge while improving traffic flow and safety on local roads. The project, which began in the summer of 2007, will include a reconstructed I-75–I-96 interchange with new connections to the Ambassador Bridge Plaza. The DIBC has a long history of aggressive inspection, maintenance, repair, and reconstruction of its Ambassador Bridge transportation asset. Working with Modjeski and Masters, Inc., the DIBC formalized its plan for the continued preservation of the bridge through the development and implementation of an asset management plan. The plan assures MDOT, FHWA, and other interested stakeholders that the structure will continue to be maintained at a level that will be compatible with ABGP and able to safely and efficiently handle any additional traffic that will be generated upon its completion of construction in 2009. The asset management plan for the Ambassador Bridge has been developed with the entire life cycle of the bridge in mind. It is based on guidance issued by FHWA including the Asset Management Primer, dated December 1999, as well as bridge specific documents such as annual inspection reports. It focuses on the existing bridge but takes into consideration that its remaining useful life, until a major rehabilitation is undertaken, may be limited. The plan includes planning, programming, engineering, construction, inspection, maintenance, and operations. It recognizes that continued and sometimes significant investment must be made with respect to a broad set of objectives, including physical preservation, congestion relief, safety, security, economic productivity, and environmental stewardship. This paper and presentation documents the development and implementation of the plan by the DIBC and how its continued implementation facilitates the safe and efficient movement of goods and services between the two countries, enhances tourism, and improves the quality of life in communities near the bridge.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
