As traffic congestion continues to increase around the country, along with the need to perform rehabilitation and reconstruction work on aging roads, maintaining work zone safety and mobility has become an increasingly complex challenge. To help address the challenge, the Federal Highway Administration (FHWA) published an updated Work Zone Safety and Mobility Rule in the Federal Register in September 2004.
