SR 505 to reopen by Saturday

WINLOCK – Contractor crews installed a concrete box culvert beneath State Route 505 this weekend, shaving a week off the timeline for emergency repairs on the undermined highway in Winlock. The Washington State Department of Transportation plans to reopen SR 505 by Saturday, April 21.

In late March, a damaged culvert opened a 15-foot-deep sinkhole in downtown Winlock and routed traffic to side streets, while the two-lane SR 505 remained closed for repairs.

Last weekend WSDOT’s emergency contractor Tapani Underground Inc. removed 24 feet of cracked concrete pipe from beneath the highway and installed a 6-foot-wide concrete box culvert.

“Our contractor located an off-the-shelf box culvert that was ready for installation,” said WSDOT Project Engineer Denys Tak. “Rather than waiting for a new culvert to be made, they were able to accelerate repair work, and now we’re at least one week ahead of our original schedule.”

Crews have already filled in the gaping hole in the highway and replaced underground drainage systems. The remaining work – repaving the highway and replacing the adjacent sidewalk – is dependent on warm, dry weather. Regardless of the forecast, WSDOT plans to reopen SR 505 by Saturday.

“April showers could mean the difference between a fully paved highway and a partially paved highway with a reduced speed limit,” Tak said. “One way or another, we’d like to see drivers back on the road by this weekend.”

The estimated $250,000 repair bill will be paid for with state highway maintenance and preservation funds. Photos of the repair work are available on WSDOT’s Flickr page.
