Project Information

  • Location: Various roads in east and west county (see below)
  • Schedule: July and August 2017 (see below)
  • Funding Source: Total project cost is about $600,000, using County General Roadway Funds

Project Description

Our crews spread oil over a paved road and then cover the oil with a thin layer of small gravel. After one to two working days, we sweep excess gravel off the road, and in about a week, it will again have the texture of pavement.

Chip sealing extends pavement life and reduces the frequency of thicker and more expensive asphalt overlays.

West County chip sealing will include:

  • Gillihan Road, from Milepost .22 to Milepost 1

East County chip sealing will include:

  • Oxbow Drive, between Altman Road and Hosner Road
  • Mershon Road, between Chamberlain Road and Historic Columbia River Highway
  • 282nd Ave, from Division Drive to Gresham city line
  • Lusted Road, from 302nd Ave to Pleasant Home Road

(An earlier version of this page also included Skyline Boulevard and Elliott Road on the west side, and Gordon Creek Road on the east side. These roads have been removed from this year's chip seals due to the fallout of extended winter operations.)

Traffic Impacts

Minor amounts of dust, loose gravel, and one way traffic occur during the operation. We recommend traveling at a reduced speed until all the loose gravel has been removed from the roadway.
