A water main break near the Garrity Interchange in Nampa has created significant traffic disruptions on Interstate 84, forcing officials to implement emergency detours and urge drivers to seek alternate routes. The break, occurring at Exit 38, has restricted traffic flow in multiple directions as crews work to assess the damage and plan repairs.
The incident is affecting both eastbound and westbound traffic on I-84 at the Garrity Interchange. Southbound traffic from Idaho Center Boulevard has been completely diverted onto the freeway, while westbound drivers at Garrity are restricted to northbound travel only. Left turns from the I-84 westbound off-ramp are prohibited. Eastbound drivers at the same interchange are limited to left turns heading north, with no southbound traffic permitted at the location.
Recommended Alternate Routes for Canyon County Drivers
To avoid the congestion at Garrity, officials have designated the Franklin Boulevard Interchange at Exit 36 as the primary alternate route for affected travelers. Drivers are strongly advised to use this detour while crews work to resolve the water main issue and restore normal traffic patterns at the Garrity location.
Nampa residents and commuters passing through the area should expect extended travel times and exercise caution when navigating the affected interchange. The water main break has created unpredictable conditions that may persist for several hours as repair crews assess the extent of the damage and determine what work needs to be completed.
Staying Informed on Road Conditions
Drivers are encouraged to monitor Idaho 511, the state’s real-time traffic information system, for current conditions and updates on when normal traffic flow will resume at the Garrity Interchange. Idaho 511 provides live data on highway incidents, lane closures, and estimated delays across the state’s transportation network.
The Garrity Interchange is a critical junction for Nampa traffic, serving as a major access point between I-84 and local roads. Disruptions at this location typically affect a wide area of Canyon County commuters, making the use of alternate routes essential for those traveling during peak hours or time-sensitive trips.

Checking Idaho 511 before heading out will help drivers avoid unexpected delays and choose the most efficient route for their destination.
As crews continue their assessment, updated information will become available through official channels and the state’s traffic monitoring system. Drivers should remain alert for changing conditions and follow all posted detour signs and traffic control measures at the interchange.
