Directions to PNNL from Seattle, Washington

There are two possible routes from Seattle to Richland. The first one listed here, through Yakima, is slightly longer but is on a four-lane interstate. The slightly shorter route, through Vantage, is on a two-lane highway.

Option 1: Traveling through Yakima

  • Take the I-5 S/I-90 E ramp towards Portland, keep left.
  • Merge onto I-90 E, traveling over Snoqualmie Pass.
  • Just past Ellensburg, take the I-82 E/US-97 S exit, number 110, towards Yakima.
  • Merge onto I-82 E, follow the interstate through Yakima. Along the way you'll pass Sunnyside and Prosser.
  • Take the I-182 E/US-12 E exit, exit number 102, towards Richland/Pasco.
  • Merge onto I-182 E.
  • Take the WA-240 W exit, exit number 4, towards Wellsian Way/Vantage.
  • Merge onto WA-240 W.
  • WA-240 W becomes the Bypass Highway.
  • The Bypass Highway becomes Stevens Drive. Continue on Stevens Drive, past an industrial area with warehouses on the left and office buildings on the right. Shortly after the speed limit changes to 55 mph, there is a KinderCare and a row of trees along the right side of the road.
  • Turn right onto Battelle Boulevard (the next right after the road to the KinderCare). You will see a tall gray sign for Pacific Northwest National Laboratory at the intersection.

Option 2: Traveling through Vantage

  • Merge onto I-90 E, traveling over Snoqualmie Pass. After passing through Ellensburg continue on eastbound I-90 until you reach Vantage, near the river.

  • Turn right at the bottom of the exit and go about one-half mile.
  • Turn right onto Highway 243 and follow it past signs for Yakima and Sunnyside.
