Transportation Engineering

Covers seismic design for typical bridge types and applies to non-critical and non-essential bridges. Approved as an alternate to the seismic provisions in the AASHTO LRFD Bridge Design Specifications.

Intended for use in the construction of bridges. The specifications employ the Load and Resistance Factor Design (LRFD) methodology, and are designed to be used in conjunction with the AASHTO LRFD Bridge Design Specifications.

These Guide Specifications address the design and construction of typical pedestrian bridges which are designed for and intended to carry primarily pedestrians, bicyclists, equestrian riders, and light maintenance vehicles, but not designed and intended to carry typical highway traffic.

These guidelines address the design of movable highway bridges using the LRFD bridge design standards.

The goal of this Manual is to completely capture the condition of bridges in a simple, effective way that can be standardized across the nation.

Provides best practices in record-keeping, bridge management, inspection, non-destructive testing, and fatigue evaluation.

The latest ASCE Report Card on the nation's infrastructure gave the U.S. bridge system a grade of C.
