The Marana Police Department is warning residents to avoid Ina Road as crews continue to clear the damage caused by a microburst late Tuesday afternoon.
According to Tucson Electric Power officials, an estimated 18 power poles were knocked down on the northwest side during the 15-minute storm.
TEP representative Joe Barrios said all the poles will have to be replaced, which is the cause for massive traffic restrictions along Ina Road.
Marana police advise motorists to avoid the area of Ina Road from Interstate 10 east to Meredith Boulevard. This area includes the intersections at Ina and Thornydale, and at Ina and Oldfather roads.
Due to the extent of the damage, police officials aren't sure how long repairs will take.
The temporary traffic plan while Tucson Electric Power works on the downed power lines is:
• Eastbound and Westbound Ina Road will be restricted to one lane from Camino de la Cruz to Thornydale Road.
• Eastbound and Westbound Ina Road will be restricted to one lane from Meredith to Shannon Road.
• There are left-turn restrictions at intersections and business entrances.
• Please use caution if you have to drive within the affected area.
Several businesses and residences along Ina Road are still without power, according to Barrios.
Officials are asking residents and motorists to avoid the area because of safety concerns with a mile of live power lines down.
Adam Goldberg, of the Northwest Fire District, said it's been a busy morning for fire crews, TEP crews and Marana town officials as they work to clean up the damage. Crews also have been working to address all the landscaping issues, including multiple trees falling.
Goldberg noted Tuesday's storm was the first major microburst of the monsoon season to cause such extensive damage.
Besides the downed power lines, Goldberg said the business center on the 4200 block of Ina Road had extensive sign damage, as well as problems with power lines to the building.
While the storm caused costly damage to power lines, businesses and landscaping, Goldberg said the good news is no one was injured.
