Multiple truck wrecks on the same stretch of I-90 have prompted officials to investigate the  roadway.

This week, two wrecks — involving multiple trucks — occurred in the westbound lanes of I-90 near Cle Elum, Washington.  In one wreck, a truck driving between mile markers 88 and 90 jackknifed. Moments later, a second truck, skidding to avoid the first truck, then jackknifed. Neither driver was injured.

The next night, just a mile down the road, another truck jackknifed and then rolled over.  This time, the driver was seriously injured.

The wrecks prompted officials to shut down the roadway — which had been replaced last fall — to investigate.  According to KOMO News, officials found that the roadway’s surface, “shows a subsequent reduction in skid resistance.”

WSDOT officials said the roadway, between mile markers 88 and 90 will remain reduced to one lane  while crews work to grind the surface to increase friction and add traction.

WSDOT is warning drivers to expect delays this weekend if you’re traveling in the area.

Really important if you’re headed WB on I-90 on Sunday. If possible, travel really early or late. Consider alternate routes. Be patient. https://t.co/TTll8sdc3u

“If drivers can either delay their trip until Monday or use alternate routes via US 97 to State Route 970, delays of several hours can be avoided,” WSDOT officials suggested.
