VDOT and Transurban launch safety campaign as crews work to open 495 Express Lanes by year-end

Drivers reminded to use caution and stay alert when traveling through the 495 NEXT project work zone in Tysons-McLean area

FAIRFAX - With construction activities on the new express lanes increasing and now concentrated in the median along the project corridor, the Virginia Department of Transportation (VDOT) and its 495 Express Lanes Northern Extension (495 NEXT) project partner, Transurban, have launched a driver safety campaign. The awareness campaign emphasizes to drivers that active roadway construction and hundreds of workers are directly adjacent to Beltway traffic. The “Closer Than You Think” campaign will leverage ads that will run on radio, as well as various social media platforms, throughout September and into October as “back to work and school” traffic resumes and drivers adjust to post-summer travel patterns.
