Chip Seal 2019

Chip Sealing 2019

Chip Sealing is complete for 2019.


Chip sealing work consists of applying asphalt to a road surface followed by a layer of one-quarter inch chips that essentially create a new layer on top of the road. A week after the chips are applied, crews return to the area to apply a sealant designed to help the chips adhere to the road. Finally, the sealant is followed by roadway striping operations. See to the right to view pictures of the process.

The roads to be chip sealed include:

  • 65th Street
  • 75th Street
  • 83rd Street
  • 87th Street
  • 95th Street
  • Hygiene Road
  • Neva & Niwot Roads
  • Overland Road west of Jamestown
  • Woodland Road
  • Yellowstone Road

See map or schedule for more details.

Chip sealing operations are part of the county’s primary network roadway rehabilitation plan. The process is intended to extend the lifespan of the roadway and postpone larger reconstruction efforts that would require more expensive work and longer travel restrictions. Primary network county roads are typically chip sealed every six to eight years.

Chip sealing is complete for 2019.

During summer of 2019, crews worked from July 15 through the end of August. Check the closures and constructions page for updates about current road projects.
