This project is substantially complete. 

The Ada County Highway District (ACHD) will begin repair work in mid-July on the east leg of the Rose Hill and Owyhee roundabout to address a drainage issue. Construction is expected to last approximately one month.*

Why the fix?

Water has been pooling in this area due to outdated design standards, construction survey errors, and a lack of proper drainage when the roundabout was originally built.

What's the solution?

ACHD will install a seepage bed to improve stormwater drainage and prevent future pooling.

Construction Impacts

  • The east leg of the intersection will be closed for the duration of the work
  • Pedestrian detours and sidewalk closures
  • General construction noise, dust, equipment backup alarms and ground vibration
  • Crews will work from 7 a.m. to 7 p.m. unless otherwise approved
  • The contractor will work with property owners to minimize impacts

*Construction schedules may change.
