Smarter Highways


Washington state's highways are getting smarter. High-tech overhead signs will display variable speed limits, lane status and real-time traffic information so drivers know what's happening ahead. This smarter highway technology will increase roadway efficiency and help drivers travel safer and smarter.

This technology is currently operating on northbound I-5 in Seattle as well as I-90 and SR 520 between Seattle and Bellevue.
