ARLINGTON – They say money is the root of all evil, but if you are a user of the Centennial Trail roots are pretty evil on their own.

Roots from trees along the trail are buckling up pavement on the route to the point repairs are needed.

Some of the repairs will take place at Marysville at Wade Road and at 108th Street.

But most of the work will be south of that from Lake Stevens to Snohomish. There will be 177 spots fixed along 8.3 miles. Pavement repairs include cut and patch, crack sealing, removal of tree roots and installation of root barrier. The work will cause intermittent closures of parts of the trail through Dec. 30.

Further north, Snohomish County Public Works is also repairing and decking the historic Railroad Bridge over Boulder River on the Whitehorse Trail. It is the next-to-last bridge repair needed as county parks moves toward the opening of the Whitehorse Trail, possibly less than a year from now. Spanning 27 miles between Arlington and Darrington, the Whitehorse Trail follows the path of the former BNSF railroad through the North Stillaguamish River Valley. The trail connects to the Centennial Trail in Arlington. Currently only a 6-mile portion of the trail from Darrington to Swede Heaven Road is open to the public.
