Sahuarita, Arizona – A crash on Interstate 19 northbound near Duval Mine Road prompted a highway closure Tuesday evening.
According to the Arizona Department of Transportation (ADOT), I-19 northbound is closed at milepost 45 near Duval Mine Road following the crash reported around 5:30 p.m. Tuesday.
Transportation officials said the closure is blocking northbound traffic in the area while crews respond to the scene and assess conditions on the roadway. Motorists traveling through the corridor between Sahuarita and Green Valley are being advised to expect delays and seek alternate routes.
ADOT stated there is currently no estimated time for reopening of the highway.
Traffic cameras from the area show vehicles stopped near the closure point, with emergency response activity visible along the northbound lanes.
Drivers traveling north toward Tucson may encounter congestion or detours as authorities work to clear the crash and reopen the interstate. Officials have not yet released details about the number of vehicles involved or whether any injuries were reported.
ADOT encourages motorists to check real-time traffic conditions before traveling through the area using the AZ511 system, which provides updates on closures, crashes, and roadway impacts across Arizona.
The agency also reminded drivers to slow down and remain alert near emergency response scenes, where traffic patterns may change quickly.
The I-19 corridor is a key commuter route between southern Pima County communities and the Tucson metro area, meaning closures can quickly affect evening travel times for workers and students.
Additional updates are expected once the crash scene is cleared and crews determine when northbound lanes can safely reopen.
