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.

Former US Route 50 and the Pioneer Route Lincoln Highway on Johnson's Pass Road

By
Johnson's Pass Road is one of the oldest highway corridors in California.  Johnson's Pass was part of the Lake Tahoe Wagon Road as it was completed during 1856 over the Sierra Nevada.  The pass would later be incorporated into the Pioneer Branch of the Lincoln Highway in 1913 and US Route 50 in 1926.  Johnson's Pass Road would be bypassed by a new alignment of US Route 50 over Echo Summit in 1938.  A replacement of the Meyers Grade east of Johnson's Pass would be opened to traffic in 1947.   Johnson's Pass Road remains accessible to traffic and is still signed by the Lincoln Highway Association.  Pictured as the blog cover is the view from the top of Johnson's Pass Road overlooking modern US Route 50 and Lake Tahoe.   Part 1; the history of Johnson's Pass Much of the history of what become the Lake Tahoe Wagon Road is discussed in the  September 1950 California Highways & Public Works  during its Centennial Edition.  The or...

Abandoned US Route 40 in the Truckee River Canyon

By
Within the Truckee River Canyon in the Sierra Nevada range numerous abandoned portions of US Route 40 can be found alongside modern Interstate 80.   This segment of highway was opened during 1926 as a bypass of the Dog Valley Grade which carried the early North Lincoln Highway and Victory Highway. The corridor of the Truckee River Canyon State Highway would be assigned as US Route 40 when the US Route System was commissioned during November 1926. During 1958 the segment of Interstate 80 between Boca, California and the Nevada state line was complete. When Interstate 80 opened east of Boca numerous obsolete portions of US Route 40 were abandoned. Some of these abandoned segments have been incorporated into the Tahoe-Pyramid Trail.  Part 1; the history of US Route 40 in the Truckee River Canyon The Truckee River Canyon for centuries has been an established corridor of travel known to native tribes crossing the Sierra Nevada range.  The first documented wagon crossi...

Former US Route 50 and the South Lincoln Highway from Folsom east to Placerville

By
The corridor of Folsom of Sacramento County east to Placerville of El Dorado County has been a long established corridor of overland travel dating back to the California Gold Rush.  The Folsom-Placerville corridor was once part of the path of the Lake Tahoe Wagon Road which became the first California State Highway and later the South Lincoln Highway.  In time the South Lincoln Highway's surface alignment was inherited by US Route 50.  The Folsom-Placerville corridor also includes the communities of; Clarksville, Shingle Springs and El Dorado. Part 1; the history of the Lake Tahoe Wagon Road, South Lincoln Highway and US Route 50 through Folsom-Placerville Folsom is located on the American River/Lake Natoma of eastern Sacramento County.  That lands now occupied by the City of Folsom were part of Rancho Rio de los Americanos prior to the finding of gold at Sutter's Mill during 1848.  During the California Gold Rush the lands of Rancho Rio de los Americanos were p...
