SR 7 - Paving and Drainage from Morton to Elbe - Complete October 2017

Project news

  • This project was completed in October 2017
  • Project was awarded to Granite Construction
  • Construction bagan in July

In summer 2017, contractor crews working for the Washington State Department of Transportation replaced several culverts underneath SR 7 between Morton and Elbe and repaved the highway. This project preserves and extends the life of the roadway and provides a smoother ride for drivers.

During construction of the culverts, highway users were alternated through the work zone via a short bypass known as a "shoofly" detour. Once paving work began, both directions of traffic were alternated through a single lane.

Why did WSDOT replace culverts and repave SR 7 between Morton and Elbe
There are four culverts that run underneath the highway that were aging and falling apart. There could have been significant highway damage if these culverts were not replaced. Once culvert replacement work was completed, crews repaved this stretch of road to preserve it for years to come. 

The End Result
This project preserved the highway and improved the ride quality for all users of the road.
