I-5 - Smarter Highways opening event
On Tuesday, Aug. 10, Gov. Chris Gregoire, Washington State Department of Transportation Secretary Paula Hammond and Federal Highways Administrator Victor Mendez celebrated as new Smarter Highways signs lit up on I-5 in south Seattle.

The high-tech traffic management system features a network of sensors and 97 electronic signs on northbound I-5 that automatically respond to changing traffic conditions and give drivers real-time information. Overhead electronic signs will alert drivers to change lanes when an incident blocks traffic ahead or to adjust their speed as they approach slower-moving traffic.

“This technology will improve the quality of life for those in the Puget Sound area,” Mendez said. “Real-time information on road conditions can help drivers with decisions that will ultimately make their commutes more manageable.”

Smarter Highways is the latest innovative transportation tool WSDOT is using to improve safety and reduce congestion, and is based on proven technology used in Europe for the past two decades.
