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Water has been pooling in this area due to outdated design standards, construction survey errors, and a lack of proper drainage when the roundabout was originally built.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

    In the spring of 2021, the Ada County Highway District (ACHD) asked the community to participate in an online survey to help us start planning improvements for the Rose Hill & Owyhee intersection. If you provided feedback- thank you!

    Based on public input and technical factors, we've developed two alternatives. Please see the information below to learn more.
