Budget Information

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

Status

July 14 2017

The roadway is open to traffic around the clock.  It had been open to one lane of traffic twice a day since Monday July 10.
 
Motorists can expect short delays with single lane traffic controlled by a portable traffic signal at only one location - MP 221 - 6 miles east of Loup Loup summit.

Here is the update for the week of July 17: 

We plan to open the pass around the clock Saturday evening July 15 with single lane traffic controlled with a portable traffic signal system at only one location - MP 221.08 - until the end of July or early August when all work is expected to be complete.
On the other 15.5 miles that have been closed since April 10 by washouts:
• MP 207.1, Frazer Creek Riprap – Complete
• MP 208.5, Frazer Creek Riprap – Complete
• MP 211.85, Roadway Failure – Paved and the guardrail installed yesterday 7/14.
• MP 211.88-212.75, Ditch Scour and Shoulder Repair – Paving completed. Large rocks being placed to armor the ditch. We expect to complete work at this location within the next week or so.
• MP 221.00, Shoulder Washout – Complete
• MP 221.08, WB Shoulder Failure and Landslide – The contractor has completed constructing the rock buttress and has stabilized the slope. The contractor is now rebuilding the slope above the buttress. Until complete, traffic will be limited to one-way signal controlled traffic.
• MP 221.4, Flash Flood Mud Slide – Debris is cleared and only site cleanup remains.
• MP 221.65, Roadway Failure – Complete
• MP 222, Mudslide blocked roadway – Debris is cleared and ditching and shaping is almost complete. Crews still need to replace a damaged 18” culvert.

All rumble strip installation, striping, etc. will be done once all the construction 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.
