road altitudes

Try bringing up "Google Earth" and put your mouse arrow on where you are leaving from and start to drag the arrow along your proposed route.
This way you will see the elevation changes as you go!
The elevation shows up in the middle at the bottom of the page.
I hope this helps?
Good Luck & Drive Safe!

great - how do i get it to show more towns so i know where i am!
all i see is faint lines - maybe there is a map view and still have the altitudes.
thanks

Depends on your starting point...I10 no real issues other than the no name grade just east of Indio...I 40 is a breeze if you use Bakersfield to Barstow and catch I40 there. As for anything big their are just rollers from that point on.

If you have a gasser be aware the loss of power at altitude .......... have heard it is 4% per 1000 feet but cannot verify that; would believe it is accurate though.

Altitude should be based on more "rate of climb"
A gradual climb may not even be noticed until you see a sign. Surprise!

I agree with enblethen, I didn't know there were such altitudes in TX. It's a long way across from DFW to El Paso and even our antique rig didn't notice any grades and while driving it, I didn't think there were mountains on the I-10. In cooking it's "low and slow" on I-10 "long and gentle".

2gypsies is right on. I-10.

But would be helpful to know starting and ending points to assist further.

Sorry, I don't understand the 'near Tucson westbound lanes' wording. What state line? Tucson isn't near a state line. It's not a big deal . .

There's a broad area around the state line at 4400'.

At the Texas Canyon rest area 61 miles east of Tucson (and 20 miles west of Wilcox), the west bound lanes are slight higher than east bound, and cross the 5000' contour.

The highest elevation along Interstate 10 occurs just east of Tucson, 20 miles west of Wilcox, at the mile marker 320 exit for the Amerind Foundation and Museum. The westbound lanes of I-10 briefly cross above 5,000 feet above sea level

Tucson is 2640 elevation. Where is it 5,000?

Great question, I too am curious

I also am curious since I need supplemental oxygen above 3000 ft. altitude.

as our old RV (and us) don't like crossing mountains...
what is the lowest altitude going from the west coast to the east coast across the mountains.
i was told that I10 is flat but elpaso is 4000 ft up!
thanks all

I-10 Near Tucson, the westbound lanes of I-10 briefly cross above 5,000 feet above sea level

I-40 Flagstaff, is highest elevation along I-40 in the US, as the road crosses just over 7,320 feet.

I-70 at Eisenhower Tunnel elevation of 11,013 feet

I-80 reaches its maximum elevation of 8,640 feet (2,633 m) above sea level between Cheyenne and Laramie, Wyoming.

I-90 Homestake Pass, WY, which is 6,329 feet (1929 m.) in elevation, the highest point for the Interstate.

When I ran long haul I looked at weather and time of year. Normally avoided I-70 west of Denver unless I was light and it was summer. LA to Indy we use to run 40 and just watched it around Flagstaff. I'd be more concerned about the grade than the elevation. I-70 has some steep grades west of Denver.
