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

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.

Interstate 375 in Detroit; a doomed freeway?

Recently while visiting the City of Detroit I drove the entirety of Interstate 375.


I-375 is a short 1.147 mile spur of I-75 in downtown Detroit which connects to the unsigned I-375 Business Spur on Jefferson Avenue.  I-375 is the southernmost segment of the Walter P. Chrysler Freeway which carried largely by I-75 in the City of Detroit.  Construction of I-375 began in 1959 and the freeway was open to traffic by late 1964 according to michiganhighways.org.

The average traffic count on I-375 ranges between approximately 14,000 vehicles at Jefferson Avenue and approximately 54,000 vehicles at I-75.  The low traffic counts on I-375 has recently led to proposals to put the freeway on a "road diet."  In 2013 the Michigan Department of Transportation announced that it may at some point in the future remove I-375.  In 2014 MDOT announced six proposals for I-375 which were eventually reduced to only two boulevard alternatives by 2017.  In late 2018 a six…

California State Route 173; former California State Route 2 and the last stand of the dirt State Highway

This past weekend I drove a portion of California State Route 173 east of CA 138 to the closure gate near Mojave River Forks Reservoir.   CA 173 is notable for being a former portion of CA 2 and having the last four miles of dirt State Highway still on the books in California.


CA 173 is a 25 mile State Highway which begins at CA 138 near Cajon Pass and ascends to CA 18 in the San Bernardino Mountains.  Presently CA 173 is the only State Highway that has a segment that has a dirt surface between Post Miles SBD 7.5 to SBD 11.5 near Mojave River Forks Reservoir.  Unfortunately said four mile segment of CA 173 has been closed to traffic since 2011.

Reportedly the route of CA 173 was originally built as an alternate haul road to Crest Drive through Waterman Canyon for the Lake Arrowhead Reservoir Project.  Lake Arrowhead Reservoir began construction in 1904 and wasn't completed until 1922.

Part of what became CA 173 appears on this 1908 USGS Map east of Cajon Pass…

Old US Route 60/70 through Hell (Chuckwall Valley Road and Ragsdale Road)

Back in 2016 I explored some of the derelict roadways of the Sonoran Desert of Riverside County which were part of US Route 60/70; Chuckwalla Valley Road and Ragsdale Road.


US 60 and US 70 were not part of the original run of US Routes in California.  According to USends.com US 60 was extended into California by 1932.  US 60 doesn't appear on the California State Highway Map until the 1934 edition.

Conversely US 70 was extended into California by 1934, it first appears on the 1936 State Highway Map.

When US 60 and US 70 were extended into California they both utilized what was Legislative Route Number 64 from the Arizona State Line west to Coachella Valley.  LRN 64 was part of the 1919 Third State Highway Bond Act routes.  The original definition of LRN 64 routed between Mecca in Blythe and wasn't extended to the Arizona State Line until 1931 according to CAhighways.org.
