Lake Washington Travel Time Signs Project - Complete April 2011

Project Status - Complete
Small map of UPA travel time projects 
This map shows the project limits.

This is an example of what the new travel time signs look like.

We added new travel time signs on SR 522, SR 520 and I-405 to help drivers get to work and back home faster with less frustration from unexpected traffic backups. These electronic signs use real-time traffic data to provide up-to-the-minute travel times to Seattle from three key locations.

Travel time signs were added at Westbound SR 520 in Bellevue (one mile east of I-405), Southbound I-405 at the NE 72nd Place overpass in Kirkland (1.3 miles north of SR 520), and Westbound SR 522 at the SR 202 overpass in Woodinville (one mile east of the I-405 northbound exit). 

How You Benefit
