Book Description







AASHTO Movable Bridge Inspection, Evaluation and Maintenance Manual


Book Description

This manual presents uniform guidelines and procedures for the inspection, evaluation and maintenance of the nation's existing movable bridge inventory. The manual provides information pertaining to the unique structural, mechanical, hydraulic and electrical components and operational characteristics of a movable highway bridge. The manual was developed for bridge engineers, inspectors and maintainers charged with operational and maintenance responsibility for these complex structures. Commentary adjacent to the text on the same page provides suggestions on implementing the guidelines and procedures of this manual and directs the reader to additional sources of information. The contents are organized in four primary parts: General, Inspection, Evaluation, and Maintenance. The appendices contain supplementary information, and are followed by a reference list, glossary, and index.




National Bridge Inspection Program


Book Description

Provides the results of an audit of the Fed. Hwy. Admin. (FHWA) to improve its oversight of states¿ bridge inspections, load ratings, and max. weight postings. FHWA should encourage states to use more detailed data to manage their bridge programs. Shortly after the I-35W bridge collapse in Minneapolis, MN on Aug. 1, 2007, killing 13 people, the Sec. of Transportation asked whether FHWA¿s Nat. Bridge Inspection Program delivered the highest level of bridge safety. Objectives for this audit were to evaluate FHWA¿s: (1) implementation of data-driven, risk-based oversight to target bridge safety risks most in need of attention, particularly those related to load ratings and postings; and (2) promotion of state use of bridge management systems.

Highway Bridge Program: Condition of Nation's Bridges Shows Limited Improvement, But Further Actions Could Enhance the Impact of Fed Investment


Book Description

This is a print on demand edition of a hard to find publication. One in four bridges in the United States is either structurally deficient and in need of repair, or functionally obsolete and is not adequate for today's traffic. The Highway Bridge Program (HBP), the primary source of federal funding for bridges, provided about $7 billion to states in fiscal year 2010. This testimony addresses: (1) the current state of the nation's bridges and the impacts of the HBP; and (2) the extent to which the HBP aligns with principles developed to guide the re-examination of surface transportation programs. This testimony is based on prior reports, updated with bridge data and information provided by agency officials. Charts and tables.
