2016 Summer Mountain West Road Trip Part 1; US Route 40 Berthoud Pass

By
Back in 2016 I took two significant road trips to the Mountain West region.  The first trip was during the summer months when all the mountain passes in the Rockies had cleared.  I flew in from California and stayed my first night in Denver.  The following day I started out by heading west on I-70 into the Rockies where I picked up US Route 40.  I took US 40 over Berthoud Pass to US 34 to reach Rocky Mountain National Park.






At the bottom of Berthoud Pass about 8,600 feet above sea level is the small town of Empire.  Empire has less than 300 residents left and founded in the early 1860s during the silver boom in Clear Creek Valley.




US 40 west of Empire begins to climb to Berthoud Pass via series of switchbacks that are largely two-lanes.  I thought the grade was pretty solid but I the climb is steep enough that the climb to Berthoud Pass is likely a dangerous one in the winter months.  Berthoud Pass lies at an elevation of 11,307 feet above sea level which makes it among the highest all-year mountain passes in the United States.


Berthoud Pass was discovered in 1861 by surveyors for the Colorado Central Railroad.  While the grade of Berthoud Pass was considered to be viable for a wagon route it was ultimately found to be too steep for railroad service.  Berthoud Pass can be see on this 1884 map of Colorado as a wagon route.

When the US Route system was created in 1926 Berthoud Pass was selected as part of the alignment in Colorado.  An early version of the US Route system in Colorado can be seen on this 1941 State Highway Map.

The views from the top of Berthoud Pass aren't the most scenic but there was a nice view of the down hill grade approaching Winter Park.

Grand Loop Road of Yellowstone National Park

By
  Grand Loop Road is a 140 mile loop highway which traverses the interior of Yellowstone National Park.  Grand Loop Road connects all of the major attractions and geological features of Yellowstone National Park along with the entrance roads.  Grand Loop Road is a seasonal highway and despite some conjecture never has been part of the US Route System.   Part 1; the history of Grand Loop Road The majority of history pertaining to Grand Loop Road was taken from the below National Park Service article: Historic Roads - Yellowstone National Park (U.S. National Park Service) (nps.gov) Yellowstone was declared the first National Park of the United States on March 1st, 1872.  The first real highway to access Yellowstone National Park came in 1873 when a tolled facility was constructed from Bozeman, Montana via Yankee Jim Canyon to Mammoth Hot Springs.  Numerous attempts were made to fund construction of roadway infrastructure during the early years of Yellows...

The last 1956-63 era California Sign State Route Spade?

By
Along southbound California State Route 170 (the Hollywood Freeway Extension) approaching the Hollywood Freeway/Ventura Freeway interchange a white California State Route 134 Sign State Route Spade can be observed on guide sign.  These white spades were specifically used during the 1956-63 era and have become increasingly rare.  This blog is intended to serve as a brief history of the Sign State Route Spade.  We also ask you as the reader, is this last 1956-63 era Sign State Route Spade or do you know of others?  Part 1; the history of the California Sign State Route Spade Prior to the Sign State Route System, the US Route System and the Auto Trails were the only highways in California signed with reassurance markers.  The creation of the US Route System by the American Association of State Highway Officials during November 1926 brought a system of standardized reassurance shields to major highways in California.  Early efforts to create a Sign State Route ...

California State Route 70; the Feather River Highway

By
From 2017 through to early 2019 I drove the majority of the California State Route 70; the Feather River Highway from CA 89 southwest to CA 99. CA 70 is an approximately 178.5 mile state highway which starts at US 395 near the Nevada State Line and travels west through the Feather River Canyon to CA 99.  CA 70 is often referred to as the Feather River Highway" given it's close association with the river.  Historically CA 70 was previously signed as US 40A and CA 24.  The Legislative Routes prior to the 1964 California Highway Renumbering that made up the current route of CA 70 are as follows: -  Legislative Route Number 21 from US 395 westward to Oroville. -  LRN 87 from Oroville south to Marysville. -  LRN 232 from Marysville to the current junction with CA 99.  CA 70 was even dual signed with CA 99 into Sacramento on what was LRN 232 for a time. The change from US 40A/LRN 21/LRN 87/LRN 232 can be seen by comparing the 1963 State Highway Ma...
