Overview

The “Terwilliger Curves” is the name of a 1.7-mile, six-lane section of Interstate 5 (I-5) in Portland, Oregon. It’s known as one of the most incident-prone high-speed corridors in the state. Between 2010 and 2013, a long-term work zone required daily setup and teardown of static signs in the median. Following an unfortunate accident where a motorist struck and injured the contractors’ TMA driver, Versilis was contracted to supply automated warning signs (SwiftSign).

Project Scope

As there is no warning leading up to on-site set up of advance warning signage, there’s always a considerable amount of risk. Curves and high-speed add to the risk and the Oregon Department of Transportation (ODOT) recognized the need to find a solution to reduce worker exposure.

ODOT approved the installation of the Versilis automated signage (SwiftSign). The approval allowed the contractor to replace all of the median standard warning signs with SwiftSigns by Versilis. For the duration of the project, all SwiftSigns were deployed and retracted using a handheld remote control. This work zone safety improvement initiative not only reduced the exposure time for workers, but it also reduced the ”surprise effect” of motorists coming up on work crews and their equipment in the transition zone.
