Nampa Highway District No. 1

Middleton & Orchard Signal

Location.  This project is located at the intersection of Middleton Rd. and Orchard Ave., on the west side of Nampa.

Description.  The intersection currently has a two-lane, all-way-stop configuration. The project will replace the stop signs with traffic signals, and add through and turn lanes, along with curb, gutter and sidewalk.

Need for Project.  This project is needed to reduce congestion and improve traffic flow through the intersection.  Approximately 12,000 vehicles per day pass through the intersection on Middleton Rd., and approximately 3,500 on Orchard Ave.  These are relatively large volumes for an intersection with stop signs, and as a result traffic back-ups regularly occur.

Process/Schedule.  The process and schedule for the project is currently as follows:

  • Select a Design Consultant – Parametrix was hired January 13, 2015
  • Public Meeting – an open house was held April 16, 2015, from 4:00 to 7:00 PM at the Nampa Church of the Brethren.
  • Concept Report – finalized June 5, 2015 and approved June11, 2015
  • Preliminary & Final Design – completed November 9, 2015
  • Purchase additional Right-of-Way – in process
  • Public Meeting – late 2018
  • Construction – start in 2019 with six month duration.

City of Nampa Collaboration.  The project is under the jurisdiction of, and is being funded by the Nampa Highway District.  The District and the City of Nampa will collaborate, however, due to the project’s close proximity to City Limits, and the likelihood the intersection will be annexed in the near future.  As part of the collaboration, the project will conform to the City’s Long Range Transportation Plan, and the traffic signal equipment will be per City standards.  The City is assisting the District in selecting a Design Engineering Consultant, and reviewing and commenting on the design.  Once built, the City will also operate the traffic signal as part of its network.

Signal vs Roundabout.  The Middleton & Orchard intersection will be signalized because Middleton Rd. and Orchard Ave. are already well developed as signalized corridors.

Several roundabouts have been built in the valley, and are performing well.  They function best, however, on corridors with stop signs or other roundabouts further up and down the line.  They are not as effective as signals on corridors which are predominantly signalized.

Middleton Rd. is already signalized at Roosevelt Ave., Karcher Rd., and Caldwell Blvd., and a new signal is planned at Flamingo Ave.  Likewise, Orchard Ave. already has signals to the east at Midland Blvd. and Caldwell Blvd.
