"The Federal Highway Administration has mandated that temporary concrete barriers (TCBs) used on federally funded projects on the National Highway System advertised after October 1, 2002 shall meet the requirements of National Cooperative Highway Research Program (NCHRP) Report 350. The State's present TCB system design is not approved as meeting the NCHRP 350 requirements, and even with modifications it is not likely to meet those standards. The Arizona Department of Transportation (ADOT) and Arizona industry partners are to evaluate many key factors in the ADOT's effort to develop an NCHRP 350 compliance plan for TCBs. Arizona intends to adopt the most valid non-proprietary TCB design, out of already approved designs, for future use in Arizona."@en . . . . . . . .
