1.1 This classification covers bridge elements and related approach work. Elements, as defined here, are major components common to most bridges. Elements usually perform a given function, regardless of the design specification, construction method, or materials used. This classification serves as a consistent reference for analysis, evaluation, cost estimating, and monitoring during the feasibility, planning and design stages of bridges. It also enhances reporting at all stages from feasibility and planning through the preparation of working documents, construction, maintenance, rehabilitation, and disposal.

1.2 This classification applies to bridges and related approach work. It excludes specialized structures such as signs and signals related to general highway use, but it does include bridge parapets, medians, drainage, and barriers needed to lessen vehicular impact.

1.3 This classification is similar to the E 1557

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
