Interchange needs to be widened and go over the train tracks. Timing of lights should also be addressed - perhaps consider double green arrows (before and after the green light) like what was done at thornydale/orange grove during the ina/i10 construction.

This is the busiest intersection crossing Interstate 10. With the train tracks delay traffic is backed up and dangerous. This intersection needs rebuilt like Ina and Twin Peaks. It is well past needing upgraded. It should have been done before Ina was done.

The interchange needs to be redone but we know this is an ADOT project, too. In the meantime, could the lights be reprogrammed so traffic moves more efficiently? Waiting for 3-4 light cycles is normal.

This intersection is one I avoid based on the wait time, congestion, and trains. The first thing they need to do is put in an overpass.

I-10/Cortaro needs a complete revamp. There is so much traffic going East/West and coming off the freeway that you can get stuck for multiple light cycles.

Agreed! This should have been done 20 years ago, before all the businesses so close to I-10 went up.

As mentioned in another comment, a lot of the traffic could be alleviated by re-programming the traffic lights, to alternate traffic from ONE direction at a time. This would allow all the traffic from each direction to get through the I-10 intersection completely in a single light cycle, regardless of their destination (continuing on Cortaro or continuing on I-10), and without having to wait for a multi-year construction nightmare.

Alternate traffic flow between EB->SB->WB->NB, and we'll be able to get a lot of traffic through in a single cycle. The way they are programmed now, you get a lot of vehicles queued up under I-10 and have to wait for at least 2 light cycles. Of course, you'll want to make sure the next lights are also coordinated (Cerius Stra. and AZ Pavilions), to ensure the traffic keeps flowing.

We should be doing this already on Avra Valley, Tangerine, Marana, or you'll be in the same situation by 2033.

Sit through this light for an hour and you will see at least 5 or more drivers turn into the wrong lane from the frontage road going East under the pass. The signage for the 2 left turn lanes is lacking. People unfamiliar with the turn don't realize the right most left turn lane is on the other side of the barriers. I see and experience this every single time I sit at this intersection

I agree with all these comments. An interchange like Ina and Twin Peaks is needed urgently. So much traffic goes through here and the traffic light timing and trains make it worse.
