Drivers will want to plan extra time if their trips include areas of State Route 110 and U.S. Highway 101 in Clallam and Jefferson counties.

Starting the week of July 22, contractor crews working for the Washington State Department of Transportation will make pavement repairs, chip seal and stripe approximately 10 miles on both highways, state officials announced.

From 6 a.m.-6 p.m. each weekday, through the end of summer, drivers will see one-way alternating traffic with a pilot car through the work zones. Travelers can expect 15-minute delays at each work zone.

When the chip seal application begins, travelers can also expect speeds reduced to 25 mph.

Work zone locations include:

• U.S. Highway 101 near Fish Hatchery Road at milepost 296.6 to milepost 299.5

• State Route 110 from milepost 0.1 near the Forks city limits to milepost 11.1

• State Route 110 Spur from the split with State Route 110 at 7.8 to milepost 10.47

Chip seal is the application of a special protective surface to existing pavement; the work extends the life of the highway and reduces the frequency of costly emergency repairs, state transportation officials said.

The work is part of a larger construction project focusing on pavement preservation across the region.

Whenever near work zones, drivers are asked to:

• drive the posted speeds;

• be kind to road construction workers;

• pay attention, both to workers directing traffic and to fellow travelers;

• and stay calm (expect delays, leave early or take alternate routes if possible).

Information about other work zones around the Olympic Peninsula is available at an online open house: engage.wsdot.wa.gov/olympic-peninsula-construction.
