HYAK – If you travel over Snoqualmie Pass you may have noticed portions of Interstate 90 look brighter.

Last fall, the Washington State Department of Transportation installed more than 4,600 solar-powered light-emitting diodes to illuminate shoulders, lane lines and barriers as part of a pilot project to improve visibility and safety on I-90. Now, WSDOT is asking drivers to take a few minutes to fill out an online survey to determine if visibility has improved on I-90.

“We know we need something on the pass that can handle the harsh weather conditions that gives drivers the ability to see the lane stripes,” said Troy Suing, WSDOT assistant regional administrator.

The pilot project was the first in the state to install lane markings with solar-powered LEDs. As part of the pilot project, WSDOT will spend the next several years monitoring the durability and longevity of the LEDs and determine if they reduce collisions. If successful, these lane markers could possibly be used in other locations along the I-90 corridor.
