Eisenhower Tunnel

[DKRITTER]

Going to be passing through the Eisenhower Tunnel from west to east in a couple weeks any advise I might need?

I've read that the height limit ranges up to 13.5... you should be fine. There are a few YouTube videos on this. Good luck!

I believe West to East is an ascent up to and through the tunnel. I have not done it personally, but I know many who travel that road frequently in RV's (summertime only) and made no significant mention other than that you have to be in the right lane through the tunnel. Some have said that they or someone traveling with them have gotten altitude sickness at that elevation at 11,000 feet, so be aware if you or your passengers start to not to feel very good. It's not uncommon and goes away as you descend.

Since we plan a Colorado trip next year, I did some research on the tunnel. The height allowed now is posted at 13’11’’. Truckers complained about the original height restrictions that were due to lighting and signage, so they modified those issues. Judy D

Once you pass Frisco is all up hill. About 6 miles long. It is a long way up. Road has a lot of potholes on the right lane. Your best bet is to stay in the middle lane. Trucks go very slow onthe right lane. Around 25 to 35 mph. It is a three lane road. If you lose speed, you will have to work hard to pick up speed again. Keep the momentum. Try not to lose speed. Pay attention to the pavement in advance because you will not have time to change lanes. Cars will pass you at high speed even going up hill and they will not slow down for you. Depending on the day and time, traffic will be heavy. If you do not feel comfortable driving in the mountains, do not cross it during weekends in the afternoons. Lots of tourists this time of the year that never drove in the mountains. AMS shouldn't be an issue. You are already at above 7-8,000 feet above sea level and you will have crossed Vail Pass before this one which is above 10K. If you want to be extra careful, recognize the early symptoms of AMS(usually headache and nausea) the only solution for that is to lose altitude quickly. That happens hours after being at that altitude. Tunnel is only two lanes. Once you drop on the eastern slope is all way down until you hit C470. DO NOT, AGAIN, DO NOT underestimate your way down, especially between Georgetown and C470. The gearbox will be your friend. Professional (not sure how professional) truck drivers end up with trailers on fire because of overheated brakes at the end of the last slope which is where I70 crosses C470. Happens every week. After that it is all flat.
All that been said, it is not intimidating at all if you know the capabilities and limitations of your rig. You will be fine. It is not a big deal. It becomes a big deal when you start sliding on ice on your way down. Don't ask me how I know. You won't have that problem this time of the year. You will be fine.

Stay in the far right lane both sides of the pass. You will come onto slower traffic and usually can see far enough ahead with time to pass in the center lane and move back to the right. Depending on your weight you may be down to 30 mph but it isn't a race to the top. More importantly is the downhill side. I will keep my speed way down in the far right lane to under 40. Over the years I have seen long lines of cars running 90+ down that mountain and many a semi with burning brakes.

A lot of good tips here. I have to ask, you mentioned C470 several times. Is that what you recommend vs staying on 70 through Denver?

I was told by several friends who live in the Denver area to always take 470, never 25 or 70 no matter what day or time.

If passing all the way through Denver on 70 I would not take 470

You didn't mention what your destination is but I will give you an idea here and then a couple of tips......C-470 is a highway that makes almost a complete circle (about 270 deg) and goes around all Denver suburbs. It is named C-470 west of I-25 and E-470 (toll road) east of I-25.
I-25 runs N-S and I-70 runs W-E. If you plan to keep going East after Denver you have two options depending on your bearing once you pass Denver.
If you head NE, then you pick up I-76 right after I-70 crosses I-25.
If you head SE then you stay on I-70 or when you come down from the mountains on I-70.
Either of these two options you will end up at what we call the "mouse trap" which is the intersection of I-70 and I-25, Heavy traffic most of the day. Traffic is heavy a mile before I-25 and a couple of miles after. Once you pass Colorado Blvd, I-70 widens and you are in the clear.
I hope this explanation makes sense.
Safe travels!
