PORT ORCHARD — Highway crews have begun adding a new roadway surface to multiple sections of three state highways in Kitsap County.

The first stretch of highway to be resurfaced is SR 3 in Poulsbo. Workers are repaving the left lane in both directions of SR 3 and ramps generally between Northwest Luoto Road (SR 308) and Northwest Thompson Road.

Workers also will upgrade traffic signal systems and enhance transitions from sidewalks to crosswalks, known as curb ramps, to create better sidewalk connections at a number of intersections.

State Route 166 in Port Orchard also will receive some roadwork attention. A portion of SR 166, generally from Bay Street to Whittier Avenue Southeast, also will be repaved.

And in Bremerton on SR 304, crews will repave Burwell Street between Warren Avenue (SR 303) and North Callow Avenue. At least one lane in each direction will be left open during daytime hours, according to the state’s Department of Transportation.

The roadwork will continue into fall, Doug Adamson, spokesman for the state agency, said.
