Bridge rehabilitation projects provide complete or nearly complete restoration of bridge elements or components. Rehabilitation work can be done on one or multiple elements and/or components of a structure. Preservation activities on several elements while a component is being rehabilitated may be included in the project. Examples of bridge rehabilitation include, but are not limited to: partial or complete deck replacement, superstructure replacement, and substructure/culvert strengthening or partial/full replacement. Incidental widening is often associated with some of these activities.
