SR 20 - Loup Loup Pass Emergency Repair 2017 - Phase 2


August 4 2017

Motorists can expect short delays with single lane traffic 24 hrs. a day controlled by portable traffic signals at MP 221 - 6 miles east of Loup Loup summit. Paving is planned for the week of August 14.

Post paving finish work such as curbing and striping continues throughout the project limits and may occasionally require a lane closure producing a short delay.

Here is the update for the week of July 28: 

Repair continues at two locations and finish work throughout the project limits:
• MP 207.1, Frazer Creek Riprap – Complete
• MP 208.5, Frazer Creek Riprap – Complete
• MP 211.85, Roadway Failure – Complete.
• MP 211.88-212.75, Ditch-Shoulder Repair – Complete.
• MP 221.00, Shoulder Washout – Complete
• MP 221.08, WB Shoulder Failure and Landslide – The contractor is now rebuilding the slope above the rock buttress. Until complete, traffic is limited to single lane signal controlled traffic.
• MP 221.4, Flash Flood Mud Slide – Complete.
• MP 221.65, Roadway Failure – Complete
• MP 222, Mudslide blocked roadway – Complete. 

Finish work including curbing, rumble strip installation, striping, etc. is underway where repair work is complete.

Why is WSDOT repairing/rebuilding the highway?
Heavy rain saturated hillsides east of the Methow Valley causing flooding and mudslides first closing SR 153 between Twisp and Pateros. On Friday morning, April 7th, a small slide came in west of Loup Loup summit on SR 20. By the end of that day, several sections of SR 20 washed out, flooded or were buried under rock and debris. Many of the hillsides above the highway were burn scarred from two previous years of fires. Unusually heavy rain saturated the soil. (Lake Conconully, less than 10 miles north of Loup Loup has recorded 238% of normal runoff.)

The End Result
A functional highway between Twisp and Okanogan

Project Benefits
New more efficient drainage features.
New guardrail, striping, signage and other safety features.

What is the project timeline?
The phase two 50 day emergency contract expires July 20.  Barring weather and other setbacks, we hope to have traffic at some level, restored shortly after Independence Day.
