Notice: Cast-in-Place Culverts

The Cast-In-Place Culverts - Single Span RCB, Twin RCB and Triple RCB dated July 2020 are designed and supplied with the Parallel Wing Headwalls. The intent of the Bureau is to use Parallel Wing Headwalls when feasible in order to provide relative parity between the CIP and Precast Culvert options.

The April 2012 Flared Wing Headwalls and CIP Culvert standards are available through the Electronic Reference Library.
