The Idaho Transportation Department (ITD) will implement nighttime lane closures at the Garrity Interchange in Nampa this week to repave sections of Garrity Boulevard beneath Interstate 84. The infrastructure work begins Friday, October 2, and is scheduled to conclude by Thursday, October 8.
Closure Schedule and Traffic Flow
Crews will restrict access to one lane in each direction during the repair window. Standard operations for weeknight shifts begin at 9 p.m. and end at 5 a.m. The Friday night session extends until 8 a.m., while Saturday night work concludes at 9 a.m. Flaggers will manage traffic flow to ensure safe access to the interchange ramps throughout the project.
Impact on Canyon County Commuters
Nampa residents and Treasure Valley commuters using Exit 38 should anticipate delays during these hours. ITD advises drivers to allow extra travel time for their morning and evening routines while the repaving takes place. The schedule remains weather-dependent, meaning crews may reschedule shifts if conditions do not permit safe construction work.
How to Track Project Updates
Motorists can monitor real-time road conditions by visiting 511.idaho.gov or using the official 511 mobile application. For text-based alerts, drivers may send the keyword 84CORRIDOR to 1-866-483-8422. These resources provide timely notifications regarding any changes to the closure timeline or lane availability.
The project focuses on maintaining roadway integrity at a high-volume interchange. By limiting work to nighttime hours, ITD aims to minimize disruption to daytime traffic patterns in Canyon County. Drivers should verify current conditions before departing, as weather delays could shift the completion date beyond October 8.
