Understanding the potential burden placed on businesses, CalTrans has put forward a phase out period for jobs continuing to use K-rail through December 31 2026, and projects advertised starting January 1, 2027 must use a MASH approved temporary barrier system only.

HV2 is a freestanding temporary barrier product that offers fast installation and exceptional safety for use on bridge decks, highways, and other road maintenance projects.
