Needles Highway

The tunnels are extremely narrow. We went thru with our mirrors in the tow (out) position on our 2005 Dodge 2500 and I only had a little clearance on each side. Wasn't paying close enough attention and rubbed the passenger side mirror. I can measure my truck with the mirrors out if you'd like the width. I would think your dually would be wider on the flares but they might just be the same.

We made it trough one tunnel at 10 feet wide. The second one we did not, it was 8 feet 2 inches wide. I’m a good driver but I wanted mirrors left on the truck when we came out the other side. So we did not d
O the second tunnel

Yes you can. Tour busses do It all the time! Now Iron Mountains Road is tight and you cannot do it in an RV or even towing a trailer. But I followed a dually through the tunnels.

Sure, just get a good running start! :W

I saw quite a bit of amber and red plastic on the road, some have trouble.

Yes, the needles are doable with a dually. Those tunnels are over 9' 6" wide, a dually is 8'. Tight fit yes, thousands of duallies go through every year. If your mirrors fit, so will the truck.
The Iron Mountain hwy ( 16a) tunnels will accomodate most any rv, but it is not recommended and why would you want to anyway? it is a scenic road built for auto traffic. There are bypass routes at each tunnel and before each pigtail bridge,

Leave the rig in a camp, enjoy the sights in your towed or a rental car.

I stand to be corrected but I thought buses could only navigate a few of the tunnels, meaning they couldn't do the loop and had to turn and return the same way they came in. That's what we were told when we were there in 2015 (Class B PleasureWay at that time). But... maybe we were misinformed.

BTW, the Needles Highway was definitely one of the BIG highlights of our cross-continent trip.

This is SD?

So what is the attraction to Needles HWY other than jeopardizing your rig? Never heard of the place.
