Learn what to expect during the roundabout construction

  • WHEN: December 10 | 8-10 a.m. and 4-7 p.m.
  • WHERE: 36th Street Garden Center & Bistro

Construction on the roundabout is planned to start as early as December 28, 2015*. Join us on December 10 to learn what to expect during the construction project and how to use the roundabout once it is complete.

Representatives from the Ada County Highway District (ACHD), Central Paving, Safe Routes to School  and others will be available to talk with neighbors about the upcoming construction.

We thank the 36th Street Garden Center & Bistro for generously providing refreshments.

Utility work to start on 36/Hill/Catalpa Intersection

10/2/15 Update: Utility work is starting in the area next week (October 5). Probst Electric will begin utility work on 36th Street between Shasta Street and Hill Road and Knife River will also start their work on Hill Road between 34th Street and Whitehead Street. The utility work is permitted from 8 a.m. to 7 p.m.

At the same time, as part of the 2015 Overlay Projects, Catalpa Drive between Collister Drive and Garden Center Way is receiving an overlay (road resurfacing). Work on this project is permitted weekdays between the hours of 9 a.m. and 4 p.m., and 6 p.m. and 10 p.m. Weekend work is also permitted between the hours of 7 a.m. to 10 p.m. The overlay work will continue until mid-October.


As early as September 28th utility work will begin in preparation for the construction of the 36th Street, Hill Road, Catalpa Street roundabout project. The goal is to have the utility work completed before construction on the roundabout starts. This will help construction go more smoothly.

What can neighbors expect during the utility work?

  • Crews will be removing a tree on ACHD’s property located on the northwest corner of the intersection. Idaho Power will also be moving power poles and trenching/boring to relocate the overhead lines underground. Most of this work will occur outside the existing intersection, but there may be temporary lane restrictions, with flaggers, when necessary.
  • United Water will begin installing a new water main along Hill Road beginning as soon as October 12th. At this time we anticipate lane restrictions, with flaggers, however short-term intersection closures may be needed.
  • Utility work is expected to occur between 8 a.m. and 7 p.m.

When will construction start on the roundabout?

We are working with the contractor to determine the best schedule; however construction could start as early as late November 2015. Once a schedule is determined we will have more information about construction impacts and what the neighborhood can expect. Sign up to receive email construction updates by filling out the form under "Subscribe" on the right side of your screen.

With the intersection being the nexus of a bustling neighborhood and shopping center, popular with bicyclists and home to Hillside Junior High School, safety will be our highest priority. We hope that with your patience and cooperation we can work together to make the utility work and construction go as safely and efficiently as possible.


We would be happy to answer any questions you might have about the utility work. Please email us at or call:
