Chipseal crews to work this Sunday on heavily-traveled roadways

Boise - To reduce impacts to busy weekday traffic, Ada County Highway District (ACHD) chipseal crews will work this Sunday (July 29) on multiple heavily-traveled roadways in Boise.

Two ACHD crews will begin work at 6 a.m. on the following roads:

  • Five Mile Road from McMillan Road to Ustick Road
  • Five Mile Road from Chinden Boulevard to Treeline Street
  • Mountain View Drive from Maple Grove Road to Skycrest Drive
  • Franklin Road from Maple Grove Road to Cole Road
  • Emerald Street from Milwaukee Street to Cole Road
  • Maple Grove Road from Chinden Boulevard to Pattie Drive
Crews will work on Sunday until they have finished chipsealing the roadways. Working weekend days on heavily traveled roads reduces impacts to traffic and allows crews to work faster and in a safer environment.

Crews will focus on residential areas next week on streets off of Ustick, Northview, Five Mile, Maple Grove and Cole. Residents will notice no parking signs along their street and will receive a chipseal notice on their door prior to the work starting.

Additionally, crews will chipseal the following roads the week of July 30:

  • Granger Avenue from Five Mile Road to Mitchell Street
  • Cory Lane from Mitchell Street to Maple Grove Road
  • Five Mile Road from Fairview Avenue to Ustick Road
  • Mitchell Street from Fairview Avenue to Ustick 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 are often 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
