Ada County Highway District

13th Street Traffic Calming (Ph 1) Fort Street to Hill Road

 Construction to start in February!

The Ada County Highway District (ACHD) will begin construction in February and finish in June of 2022. 

Construction that will include installing enhanced pedestrian crossings at Resseguie, Sherman, Heron, Hazel, and Bella streets, adding radar speed limit signs near Irene and Fort streets, and replacing the sidewalk along west side of Camel's Back Park. 

What to expect during construction: 

  • Lane Restrictions 
  • Temporary on-street parking impacts
  • Short-term closures
  • Temporary pedestrian detours
  • Equipment back up alarms and ground vibration
  • General construction noise and dust

Contractors will coordinate with property owners to maintain access during construction and crews will work between 7 a.m. to 7 p.m., unless otherwise approved. 

Due to contractor staffing issues and supply-chain shortages, construction schedules could change.

Project Highlights 

  • Install radar speed limit signs near both ends of the project: one just south of Resseguie Street and another near Irene Street.
  • Add bulb outs and pedestrian ramp upgrades at five intersections along 13th Street (Ressequie, Sherman, Heron, Hazel and Bella). Approximately one parking spot on each side of 13th Street will be removed to install each bulb out.
  • Install a Rectangular Rapid Flashing Beacon (RRFB) at the Resseguie Street and 13th Street bulb out to increase safety at the pedestrian crossing near North Junior High.
  • Replace sidewalk along the west side of Camel's Back Park and restore parallel parking.
  • Improve street and intersection lighting as needed.

Construction is anticipated to start February 2022 and be complete in late spring.

Phase 2

  • Phase 2 of the 13th Street Traffic Calming project will construct sidewalk on the north side of Hill Road starting near the 13th Street and Bella Street intersection and will extend to 15th Street. This phase of the overall project is not currently programmed/budgeted for design or construction but was adopted by the ACHD Commission as part of the Concept Design on July 25, 2018.
