Trans-Sierra Highway Passes; Interstate 80 Donner Summit

Back in 2016 I attempted as many Trans-Sierra Highway Passes as I could upon my return to California.  I started with Interstate 80 over Donner Summit during the late winter on the way to Lake Tahoe and Virginia City.


Donner Summit is actually located north of the 7,056 foot Donner Pass.  Donner Summit has a listed height of 7,277 feet above sea level which is listed at the rest area on the eastbound lanes heading towards Truckee.


As I-80 begins to descend from Donner Summit there is an overlook of Donner Lake and Donner Pass.


US 40, the Lincoln Highway, First Trans-Continental Railroad, and the Dutch Flat & Donner Lake Railroad all crossed Donner Pass on various different alignments to the south of Donner Summit.


Previously I wrote a blog about Donner Pass which includes a history of early pioneer crossings, the Donner Party, the Dutch Flat & and Donner Road, the Lincoln Highway, and of course US 40 which can be found here:

Regarding Donner Summit and Interstate 80; it's construction was meant to replace US 40 and bypass Donner Pass Road.  I borrowed this excerpt from my Donner Pass Road blog regarding the construction timeline of I-80 over Donner Summit:

"Not much changed with Donner Pass Road until the Federal Aid Highway Act of 1956 which of course led to the Interstate system.  The first visual change that can be seen on the state highway map with Donner Pass Road being bypassed is in 1960 when a new stub of I-80 is shown running from the Nevada state line west past Truckee to Donner Lake.

The adopted routing of I-80 on Donner Summit appears on the 1961 State Highway map.

On the 1965 State Highway Map Donner Pass Road is shown being bypassed by I-80 via Donner Summit, but US 40 still shown as present in California.

It isn't until the 1967 State Highway Map that US 40 completely disappears from California.

I-80 and Donner Summit are very apparent from the air.  Back in May I took some photos on a flight to Seattle which can be seen here:

What's In a Name?: When the Roads Really Do Tell a Story

  Our tagline on the Gribblenation blog is "because every road tells a story". Some roads tell different stories than others. Along our travels, we may see historic markers that tell us a little story about the roads we travel or the places we pass by. Some historic markers are more general, as to telling us who lived where or what old trail traversed between two towns. During my travels across New York State and other states or provinces, I pass by many historic markers, some with interesting or amusing references to roads. I wanted to highlight a few of the markers I've seen along my travels around the Empire State and help tell their stories. Those stories may be as specific as explaining the tales of a tree that was used to help measure a distance of eight miles from Bath to Avoca in Steuben County, as referenced on the Eight Mile Tree historical marker above. They may also help point the way along historical roads first used centuries ago, or may help tell a local l...

2018 Mojave Road Trip Part 2; The deadly desert highway (California State Route 127 and Nevada State Route 373)

After leaving Barstow via Old Highway 58 my next destination was in Death Valley.  To access Death Valley from rural San Bernardino County required a trek on north on Interstate 15 to California State Route 127 which becomes Nevada State Route 373 at the state line. Along I-15 I encountered the road sign oddity that is Zzyzx Road about eight miles south of Baker.   Zzyzx Road is a four mile road that used to go to the Zzyzx Mineral Springs and Health Spa.   The spa was founded in the 1940s and the owner made up the name "Zzyzx" to claim it was the last word in the English Language.  The spa has been shut down since the 1970s and is now part of a Desert Studies Center for California State University. The southern terminus of CA 127 in Baker is located at I-15 exit 246.  CA 127 is a 91 mile north/south highway which runs to the Nevada State Line in Inyo County.  CA 127 is called Death Valley Road from I-15 northward.  South of CA 127 ...

May 2023 Ontario Trip (Part 3 of 3)

  Over the years, I have made plenty of trips to Ontario, crisscrossing the southern, central and eastern parts of the province. Living in Upstate New York, it's pretty easy to visit our neighbor to the north, or is that our neighbor to the west? Ottawa is one of my favorite cities to visit anywhere in the world, plus I've discovered the charm of Kingston, the waterfalls of Hamilton (which is on the same Niagara Escarpment that brings us Niagara Falls), the sheer beauty of the Bruce Peninsula, and more. But I hadn't explored much of Cottage Country. So I decided to change that, and what better time to go than over Memorial Day weekend, when the daylight is long and I have an extra day to explore. On the third and final day of my trip, I started in Huntsville and made my way through Muskoka District and Haliburton County, passing by many lakes along the way. I stopped in towns such as Dorset, Haliburton and Bancroft before making a beeline down to Belleville and then over th...
