2011 Overlays (Road Resurfacing Work)

General Description:

Construction on the 2011 Overlays began in July in some locations and will continue into November.  A list of locations and approximate time frames available is listed below.

Please check this page regularly for updates to construction schedules, as they are subject to change. Please call if you have any questions, (208) 387-6100.


What is an overlay?

Each year the condition of roads throughout Ada County is closely assessed and a priority system is used to determine which roads have the greatest need for re-surfacing. Overlay work generally involves the milling and removal of two inches of existing (failed) asphalt. A fresh layer of asphalt is then applied to the roadway, which will also receive new lane markings. The road segments selected are based on an in-depth ranking system that accounts for wear and deterioration.

Pedestrian sidewalk ramps located along the overlay road sections will be removed and replaced if they are not in compliance with Americans with Disability Act (ADA) standards.

Impacts During Construction

Overlay work is typically a fast moving process, but includes several steps, some of which can involve, but are not limited to:

  • General construction noise
  • Ground vibration
  • Equipment safety back up alarms
  • Dust
  • Night work lighting
  • Temporary lane restrictions & delays
  • Pedestrian impacts (sidewalk ramps not compliant with Americans with Disabilities Act (ADA) standards will be removed and replaced)

Some overlay locations are scheduled for night work to occur, typically between the hours of 7 p.m. and 5 a.m. Performing night work allows construction to occur faster and under safer conditions for residents, motorists and crews and reduces the need for lane restrictions or closures.
