2016 Summer Mountain Trip Part 32 (Finale); former US Route 40 in Idaho Springs

Upon leaving Georgetown I returned to US 6/I-70 eastbound.  My next stop was in downtown Idaho Springs to what was US Route 40 on Miner Street.


This article serves as the 32nd entry and Finale of the 2016 Summer Mountain Trip Series.  Part 31 discussed the history of US Route 6 and Colorado State Route 91 in Georgetown.

2016 Summer Mountain Trip Series Part 31; former US Route 6 and Colorado State Route 91 in Georgetown

Idaho Springs is a City located in Clear Creek Canyon of Clear Creek County off of Interstate 70/US Route 6/US Route 40.  Idaho Springs is located at the confluence of Clear Creek and Chicago Creek.  Said confluence of Clear Creek and Chicago Creek was the site of a major gold strike made by prospector George A. Jackson on January 5th 1859.  Jackson was attracted to the confluence of Clear Creek and Chicago Creek due to steam that was rising from a nearby hot spring.  Jackson kept his claim secret for several months but soon word spread and a small community by the name of "Jackson's Diggings" would soon arise.  The community of Jackson's Diggings would later use the names of; "Sacramento City," "Idahoe," and "Idaho City" before the modern name of "Idaho Springs" took hold.  Idaho Springs was one of the earliest communities to spring to life during the Pikes Peak Gold Rush.

As noted in Part 29, Part 30, and Part 31 the corridor of Loveland Pass is one of the oldest transportation corridors through the Rockies.  Loveland Pass traces it's origins back to a wagon road constructed through Clear Creek Canyon by William A.H. Loveland in 1863-1864.  The Loveland wagon road up Clear Creek Canyon to Loveland Pass was built to take advantage of the numerous mining stamp mills that popped up during the Pikes Peak Gold Rush.  Idaho Springs being located at the confluence of Clear Creek and Chicago Creek was a primary hub of the Loveland Wagon Road.

During the Auto Trail era the road through Idaho Springs remained a major corridor of travel.  The Midland-Roosevelt Trail is shown being aligned through Idaho Springs en route west to Berthoud Pass on the 1924 Rand McNally Regional Highway Map.   By 1921 the Victory Highway was also formed which was also aligned Idaho Springs. 


By November 1926 the US Route System was finalized.  US Route 40 was aligned west of Denver by way of Clear Creek Canyon and Berthoud Pass.  The 1927 Rand McNally Highway Map of Colorado shows US Route 40 co-signed with the Victory Highway through Idaho Springs.  


Topographical Maps indicate that early US 40 westbound entered downtown Idaho Springs by way of Miner Street.  US 40 appears to have taken a jog north on 13th Avenue where it continued west on Colorado Boulevard towards Empire.  By 1931 a new bridge had been built over Clear Creek and extended Colorado Boulevard into a bypass of downtown Idaho Springs.  It isn't fully clear but it appears that US 40 was realigned onto Colorado Boulevard following the opening new bridge over Clear Creek.  A plaque on the Bridge over Clear Creek on Colorado Boulevard can be seen here on Google Street View

By 1937 US 6 was extended from Greeley, CO to Long Beach, CA according to USends.  US 6 multiplexed US 40 through Idaho Springs and split away towards Loveland Pass at Empire, this can be see on the 1939 State Farm Insurance Map of Colorado.  US 40/US 6 would remain on Colorado Boulevard in Idaho Springs until the grade of I-70 was constructed south of Clear Creek.


I pulled into Idaho Springs via I-70/US 40/US 6 Exit 240 and onto 13th Avenue.  I parked on Miner Street and began my walking tour of former US 40 eastbound.  The first attraction that caught my eye was Idaho Springs Fire Department Station #1 at the northwest corner of Miner Street and 14th Avenue.  The 1905 Idaho Springs Library can be seen in the background behind Station #1.

Idaho Springs City Hall can be found at the southeast intersection of Miner Street and 17th Avenue on the banks of Clear Creek.  Idaho Springs City Hall was originally known as the Grass Valley School and was located at the present site of Safeway.  The Grass Valley School was donated to the City of Idaho Springs, the City moved the structure and relocated City Hall there during 1988.

From Idaho Springs I returned I-70/US 40/US 6 and followed I-70 all the way east into Denver.  I had an extra day in Denver that I saved just in case my trip was delayed for any reason.  Unfortunately, I ended up spending the day watching a terrible movie (Independence Day Resurgence) instead of doing something more grand in scale.  The following morning I took Pena Boulevard back to the rental car facility at Denver International Airport and headed back home to Florida.  Back during 2019 I did cover the interestingly ominous Pena Boulevard and Denver International Airport which can be found below:

Mineral King Road, the White Chief Mine, and the unbuilt California State Route 276

Back in July of 2016 I took Mineral King Road east from California State Route 198 to Mineral King Valley within the Sierra Nevada Mountains of Sequoia National Park.  This June I revisited Mineral King Valley and made my way up to the White Chief Mine.


Mineral King Road is a 24.8 mile rural highway maintained by the National Park Service and as Tulare County Mountain Road 375.  Mineral King Road originates at California State Route 198 in Three Rivers near the confluence of the Middle Fork Kaweah River and the East Fork Kaweah River.  Mineral King Road climbs from a starting elevation of 1,400 feet above sea level to 7,830 feet above sea level at the White Chief Mine Trailhead in Mineral King Valley.  Notably Mineral King Road is stated to have 697 curves.


Mineral King Road has an average grade of 5.1% but has several stretches between 15-20% in places.  Pjammycycling has a detailed breakdown on the grade levels over the entirety of Mineral King Road.

Hetch Hetchy Valley; Hetch Hetchy Railroad, abandoned Lake Eleanor Road, and the Wapama Fall Bridge

This June I took a trip out to Yosemite National Park upon receiving my COVID-19 Day Use Reservation.  My destination in Yosemite National Park was out in Hetch Hetchy Valley.  I sought to hike to the Wapama Fall Bridge which took me through some of the path of the former Hetch Hetchy Valley Railroad and abandoned Lake Eleanor Road.



Part 1; Hetch Hetchy Valley, the Hetch Hetchy Railroad, and reservoir roads

Hetch Hetchy is glacially carved valley similar to Yosemite Valley which is located on the Tuolumne River of Tuolumne County.  Hetch Hetchy Valley presently is impounded by the O'Shaughnessy Dam which was completed during 1923 as part of a project to deliver water and hydroelectric power to the City of San Francisco.  Before being impounded Hetch Hetchy Valley had an average depth of approximately 1,800 feet with a maximum depth of approximately 3,000 feet.  Hetch Hetchy Valley is approximately three miles long and as much as a half mile wide.  Hetch Hetchy Valley is located dow…

California's Rogue Sign State Route Shields

While recently revisiting Yosemite National Park I took a couple minutes to capture some of the California Sign State Route shields posted by the National Park Service ("NPS").  None of the NPS shields were actually posted on roadways maintained by Caltrans but were clearly intended to create route continuity with the Sign State Highways.  This phenomenon is not exclusive to Yosemite National Park and can be found on numerous roads not maintained by Caltrans throughout California.



Part 1; Route continuity over who maintains the route

In the very early era of State Highways in California the Division of Highways didn't actually field sign the Auto Trails or even US Routes.  The responsibility of Highway signage fell to the California State Automobile Association ("CSAA") and Automobile Club of Southern California ("ACSC").  The Auto Clubs simply signed Highways on roadways that best served navigational purposes.  These navigational purposes often didn&#…
