Lengthy traffic delays are expected during a two-week repaving project on Issaquah-Hobart Road.

King County road officials said the project will begin July 31 on a section from Southeast May Valley Road to State Route 18. The work will be done on weekdays from 8 a.m. to 4:30 p.m., depending on weather conditions, and is scheduled to be finished by Aug. 15.

Traffic will be restricted to one lane and will be led through the work zone by a pilot car. A spokeswoman for the county’s road services division said motorists should expect delays and may want to use alternate routes or travel before 8 a.m. and after 4:30 p.m.

Issaquah-Hobart Road is used heavily as a north-south commuter route in the southeast King County area.

After the repaving, crews will place rock on the road’s shoulder and paint stripes, which should cause only minimal and localized traffic disruptions, officials said.
