ACHD is designing temporary traffic calming features for Rose Hill Street from Roosevelt Street to Vista Avenue to enhance the safety for all users.

The concept design was created through a community outreach process and parking analysis and was adopted by the ACHD Commission in Fall 2022.

The project will provide a variety of traffic calming measures and enhanced bicycle infrastructure along Rose Hill Street.

Project Description

  • Add on-street bike lanes, separated by a painted buffer with a vertical element.
  • Remove the continuous center left-turn lane in most areas.
  • Retain parking on one side of the street, except between Latah and Owyhee streets, alternating sides of the street to provide shifts in the travel lanes.

* Design of the Rose Hill and Owyhee mini-roundabout was completed as a separate project.

    The Ada County Highway District (ACHD) will be building a mini-roundabout at the Rose Hill and Owyhee intersection, as well as updating Rose Hill between Roosevelt and Vista with temporary traffic calming features. The goal of both projects is to slow down traffic and improve the street for all users. Construction will start as early as late May 2024* and completion is expected Fall 2024.


    Project Description

    • Construct a mini-roundabout at the Rose Hill and Owyhee intersection with Rectangular Rapid Flashing Beacons (RRFB) at each pedestrian crossing.
    • After chip sealing Rose Hill Street, temporarily reallocate street space and remove center turn lane (in most areas) to provide:
      • Bike lanes on both sides of the street, with vertical elements and painted buffers.
      • On-street parking on one side of the street, except between Latah Street and Owyhee Street, alternating sides of the street to help slow traffic.


    Traffic and Construction Impacts

    • Temporary pedestrian detours.
    • On-street parking impacts.
    • Lane restrictions with flaggers.
    • General construction noise, including equipment backup alarms, dust and ground vibration.
    • The contractor will coordinate with property and business owners to maintain access or provide alternative access.
    • Utility work
