Culvert Selection

The FHWA's policy for culvert and storm sewer material type selection is that State transportation departments and direct recipients of Federal-aid highway construction funds shall have the autonomy to determine culvert and storm sewer material types to be included in Federal-aid highway construction projects.

Authority/Legal Basis

  • 23 CFR 635.411 Culvert and Storm Sewer Materials Types (9/27/19) On September 27, 2019, FHWA revised its regulation at 23 CFR 635.411 by issuing a Final Rule in the Federal Register rescinding the long-standing proprietary product regulatory requirements in 23 CFR 635.411(a) through (e) and change the title of section 635.411 to 'Culvert and Storm Sewer Materials Types.' Under its new title, the former paragraph (f) of section 635.411 would be retained to fulfill the mandate of section 1525 of the Moving Ahead for Progress in the 21st Century Act (MAP-21) for States to retain autonomy for the selection of storm sewer material types.
