Note to paragraph (a): Federal Highway Administration (FHWA) regulations incorporate by reference a number of standards, policies, and standard specifications published by the American Association of State Highway and Transportation Officials (AASHTO) and other organizations. (See23 CFR 625.4 ). Many of these incorporated provisions may be relevant to maintaining structural stability during the erection process. For instance, as of May 17, 2010, in many cases FHWA requires a Registered Engineer to prepare and seal working drawings for falsework used in highway bridge construction. (See AASHTO Specifications for Highway Bridges, Div. II, § 3.2.1 , 15th edition, 1992, which FHWA incorporates by reference in 23 CFR 625.4 ). FHWA also encourages compliance with AASHTO Specifications that the FHWA regulations do not currently incorporate by reference. (Seehttp://www.fhwa.dot.gov/bridge/lrfd/index.htm.)
