Chipseal crews to work on busy roadways during daytime hours; traffic delays expected

The Ada County Highway District’s (ACHD) annual chipseal maintenance season is underway and crews are working on both residential and heavily traveled streets. Chipsealing must be done in warmer temperatures – daytime sun and heat are essential to the curing process, which eliminates the option of doing the work at night. Motorists should expect delays between five and 15 minutes long during certain steps in the chipseal process.

On Thursday (July 19), crews will apply a chipseal on Five Mile Road between Overland Road and Franklin Road. Next week, crews will work in the following locations; however chipseal schedules are subject to change:

  • Emerald Street from Five Mile Road to Maple Grove Road
  • Maple Grove Road from Emerald Street to Fairview Avenue
  • Mitchell Street from Emerald Street to Fairview Avenue
  • Mitchell Street from Skycrest Drive to McMillan Road
  • Mitchell Street from Edna Street to Ustick Road
  • Fairview Avenue from Five Mile Road to Milwaukee Street
  • Jullion Street from McMillan Road to Edna Street
  • Edna Street from Five Mile Road to Maple Grove Road
  • McMillan Road from Mitchell Street to Maple Grove Road
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 in place of a traffic signal, which must be turned off during the intersection work. Traffic delays may be longer when crews are working in major intersections.

Crews will also be working during the early morning hours on weekends when traffic is lighter and impacts to the traveling public are reduced.

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-September. For chipseal zone maps and more information, visit www.achdidaho.org.
