🚧 Amity Ave. Closure Update
The closure on Amity Ave. between Robinson Blvd. and McDermott Rd. has been extended.
As crews began the repair, they found that the roadway damage was more extensive than originally anticipated. This means the repair is taking longer than expected, and the road is now anticipated to remain closed through approximately Tuesday, September 15th.
We understand that extending the closure may cause additional inconvenience, and we appreciate everyone's patience as crews work to properly address the underlying issue rather than making a temporary repair.
Please continue to use an alternate route and plan accordingly.

📢 Sharing for Public Information:
We know this intersection has been a frequent source of questions and calls from our community, so we wanted to share the latest information released by the Idaho Transportation Department (ITD).

This is a joint project between ITD and the City of Nampa. Nampa Highway District No. 1 is not involved in the project, but we’re sharing ITD’s update to help keep our community informed.

Please see ITD’s original post below for more information and updates.

We understand the community’s frustration with the unfinished work at Locust Lane and SH-45.

ITD’s project has been temporarily halted for contractual reasons that we are addressing as we attempt to complete the work as quickly as possible. ITD must hire a new contractor but must do so following the mandatory bonding process, which ensures that Idaho taxpayers do not pay twice for the same work.

ITD is preparing a temporary solution that will enhance mobility of the roadway until a new contractor is hired and the project can be completed. We know the delay is disruptive, and we are sorry for the disruption. We will provide additional information as the path forward and schedule are confirmed.
