US Route 101 and the Last Chance Grade

By

 
 
The Last Chance Grade of US Route 101 refers to a segment of the highway in Del Norte County, California from Crescent City southward through Del Norte Coast Redwoods State Park.  The Last Chance Grade traditionally has been a slide prone choke point through much of the history of US Route 101 and the Redwood Highway.  




The history of the Last Chance Grade

Prior to a highway being constructed over the Last Chance Slide overland transportation between Crescent City southward to Klamath River was virtually non-existent.  Travelers and freight would arrive in Crescent City where it they would be loaded onto rowboats.  The rowboats would follow the coastline southward and turn inland via the Klamath River to the village of Requa.  Requa and the Klamath River served as the gateway to reach Klamath County (annexed into Humboldt County by 1874).  This corridor between Crescent City and the Klamath River can be seen on the 1873 Bancroft's Road Map of California. 


The 1884 California Office of the State Engineer Map of Del Norte County also shows no established foot path or road from Crescent City south to the Klamath River.  Notably a foot path is shown existing from Wilson's Creek south to the Klamath River.  


In 1888 the Del Norte County Board of Supervisor's authorized construction of a road from Crescent City south to Requa and the Klamath River.  This road was placed under construction in 1889 and was known as the Crescent City-Requa Road.  The Crescent City-Requa Road would be completed by 1895 and ascended the notable slope of the Last Chance Slide.  Journeys on the Crescent City-Requa Road were made via four horse or six horse teams which took ten to sixteen hours to complete depending on the weather conditions.  Fare for a trip on the Crescent City-Requa Road cost travelers a fee of $5 dollars.  

Much of the Crescent City-Requa Road was constructed by way of use of Coastal Redwood puncheons.  A photo of a derelict segment of the Crescent City-Requa Road can be seen in the March 1934 California Highways & Public Works.  

The history of what would become US Route 101 ("US 101") over the Last Chance Grade begins with the approval of the 1909 First State Highway Bond Act.  The First State Highway Bond Act was approved by voters during 1910 and was the genesis point of some of the most notable highways in California.  Legislative Route Number 1 ("LRN 1") as originally plotted was a new State Highway which was designated between San Francisco north to Crescent City.  The route of LRN 1 would be extended to the Oregon State Line during the 1919 Third State Highway Bond Act and became be known as the Redwood Highway.  LRN 1 can be seen aligned over the Last Chance Grade via the Crescent City-Requa Road on the 1917 California State Automobile Association Map. 

The existing Crescent City-Requa Road was upgraded and modernized to State standards by 1920.  Much of the previous Redwood puncheon roadway from Crescent City south to Wilson's Creek was abandoned as it was not suited to automotive traffic.  This 1920 alignment of LRN 1/Redwood Highway now exists as Enderts Beach Road and the California Coastal Trail in Del Norte Coast Redwoods State Park.  LRN 1 and the Redwood Highway can be seen aligned over the Last Chance Grade between Crescent City-Requa on the 1920 Clason Highway Map of California.  

In November 1926 the US Route System was created.  US Route 101 from San Francisco north to Crescent City was aligned over the Redwood Highway.  Both US 101 and the Redwood Highway between Crescent City-Requa can be seen on the 1927 Rand McNally Highway Map of California.  

The March 1934 California Highways & Public Works describes the nearly completed realignment of US 101 and the Redwood Highway south of Crescent City.  Specifically new alignment of US 101/Redwood Highway would eliminate 205 curves south of Crescent City to the Last Chance Slide.  The new alignment of US 101 was cited to have only 34 curves which shortened the distance between Crescent City and the Last Chance Slide from 10.31 miles to 9.52 miles.  The article cites the new alignment of US 101 and the Redwood Highway as having expected completion date by late 1934.  Note; the history of the Crescent City-Requa Road can be found in the March 1934 California Highways and Public Works.





The September 1935 California Highways & Public Works features the formal dedication of the US 101/Redwood realignment south of Crescent City to the Last Chance Slide.  The formal dedication ceremony took place on August 18th, 1935.  



The 1935 California Division of Highways Map of Del Norte County displays the new alignment of US 101 south of Crescent City to the Last Chance Slide alongside the 1920 alignment.  

Since 1935 US 101 and the Redwood Highway have changed minimally.  The climb via the Last Chance Grade still has the signature vista of Crescent City described in the September 1935 California Highways & Public Works and serves as a boundary of the Redwood National Park & State Parks system.  









According to CAhighways.org from July 2012 to February 2013 the Last Chance Grade experienced over 200 slides.  The road deck of US 101 subsequently slid 13 inches horizontally and 10 inches vertically.  In March 2014 Caltrans established the Last Chance Grade Partnership to work with local authorities on the feasibility of realigning US 101 off the Last Chance Grade.  As of 2019 Environmental studies have been continuing to progress regarding potential realignments of US 101.  This image snip from CAhighways.org shows the multiple alignments under study from Postmile DN 19.81 south to DN 13.47.

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

By
  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)

By
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)

By
  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...
