Residents using King County’s Snoqualmie Valley Trail in North Bend will need to find alternate routes beginning this week due to replacement of decaying timbers on a bridge. The repairs will mean a three-week closure of a portion of the popular trail.

The bridge is a quarter-mile north of the Main Avenue North intersection in North Bend and spans the South Fork of the Snoqualmie River.

King County crews will replace the decaying timbers and remove all of the decking and handrail along the bridge as part of the work. The bridge will be impassable for the duration of the repair project, which should be completed by mid-October at a cost of about $70,000. Project costs are being covered by the division’s capital improvement budget, which is funded by Real Estate Excise Tax funds.

The nearest access points on either side of the closed portion of the trail are Main Avenue North and Reinig Road.
