Chipseal crews to work this Sunday and next week; season ahead of schedule

Boise – With the chipseal season reaching its final weeks, Ada County Highway District crews will work this Sunday to apply a fogseal to three heavily traveled roads in Boise that have recently been treated with a chipseal. The fogseal is the final step in the process that seals loose rocks in place.

On Sunday (August 5) ACHD crews will begin work at 6 a.m. and will apply a fogseal on the following roads:

  • Fairview Avenue from Five Mile Road to Cole Road
  • Emerald Street from Milwaukee Street to Cole Road
  • Franklin Road from Bird Street to Cole Road
Once a fogseal has been applied, vehicles can drive on it after approximately 30 minutes. Motorists should expect lane restrictions and possible delays during fogseal work.

Working on weekends along heavily traveled roads reduces impacts to traffic and allows crews to work faster and in a safer environment.

Additionally, crews will chipseal or fogseal the following roads the week of August 6 in Boise and Garden City – please see the attached map:


  • At Five Mile Road and Ustick Road – short segment north on Five Mile
  • 37th Street, 42nd Street, 44th Street, 50th Street and Kent Street between Chinden Boulevard and Adams Street
  • Adams Street from 37th Street to Kent Lane
  • Liberty Street between Northview Street and Fairview Avenue
  • Ustick Road between Cole Road and Esquire Drive
Fog Seal

  • Between Victory Road and Overland Road from Five Mile Road to Maple Grove Road
Chipseal Impacts

Once a chipseal is applied to the road, vehicles are immediately allowed to drive slowly over the new surface, however caution should be used. At signalized intersections, flaggers may be used to direct motorists. Traffic delays may be longer when crews are working in major intersections. Motorists should expect delays between five and 15 minutes long during certain steps in the chipseal process. Additional impacts include large equipment and crews working in the roadways, sometimes close to traffic.

About Chipsealing

Chipsealing helps combat the deterioration of roads caused by sun and weather and involves a multi-step process that helps seal the road surface, providing an armor coat for skid and weather resistance.

ACHD’s chipseal season is anticipated to wrap up in mid-to-late August. For chipseal zone maps and more information, visit
