The Office of Federal Lands Highway (FLH) is part of the US Department of Transportation (USDOT) Federal Highway Administration (FHWA), and works in cooperation with federal land management agencies to plan, design, construct and rehabilitate highways and bridges on federally owned lands. In support of this mission, FLH has developed these project-level guidelines for assessing the condition and performance of existing roadway culverts, and when necessary, selecting corrective actions to be taken for any deficiencies found as part of specific project development activities. This procedures manual is intended to aid users in implementing a fully integrated culvert assessment and decision-making tool that provides guidance for selecting replacement or rehabilitation alternatives.
