Drivers at the Steptoe Street-Columbia Park Trail roundabout can expect minor delays during nighttime restriping this week, according to a Washington State Department of Transportation.
Lanes will be intermittently closed 9 p.m. to 5 a.m. nightly through Friday, the department said. Flaggers will direct drivers through the work zone.The striping is part of a statewide project, said department spokeswoman Summer Derrey.
“It kind of happens in stages,” she said. “They do certain types of striping at certain times.”
The Steptoe roundabout restriping, which costs $218,000, has been going on since late August, said WSDOT field engineer Travis Beebe. It is expected to wrap up Oct. 11.

The striping has taken longer than it has in the past because workers are using a new process where they insert new arrows and stripes into the road using a plastic compound, Beebe said. That involves cutting out part of the existing road.
“We are actually inlaying it into the concrete,” he said.
The new system is expected to only have to be reapplied every five to seven years, Beebe said. Workers have had to replace painted markings every year after they were ground down by snowplows and other vehicles.
Crews will move on to restriping the “dogbone” roundabout at Highway 395 and Highway 240 Oct. 12-16 and a stretch of Highway 240 Oct. 17-19, Derrey said.
