The Sierran Death Highway, Blackrock Road

Back in 2016 I was pursuing dangerousroads.org looking for a interesting paved road akin to Kaiser Pass Road and Mineral King Road both which I had done earlier in the year.  I found what I was looking for in Blackrock Road located in rural eastern Fresno County at the confluence of the Kings River with it's North Fork.


Suffice to say that if I was looking roadways on dangerousroads.org it probably lends suggestion that Blackroad is somewhat on the hazardous side, it is.  Blackrock Road is an approximately 26-27 mile long one-lane road located in Sierra National Forest.  Blackrock Road is partially paved running from the Bailey Bridge at the Kings River north to the Wishon Reservoir roughly following the west bank of the North Fork Kings River.  Every documentation I've seen shows the road is really spelled "Blackrock" as opposed to "Black Rock" like the nearby Pacific Gas & Electricity Reservoir.

My goal on Blackrock Road was simple; I wanted to see all the unique bridges the roadway has to offer and the wide canyon view above Balch Camp.  I headed out in the morning took Trimmer Springs Road all the way east to the Bailey Bridge.






I would speculate that the Bailey Bridge was built sometime during construction of the Black Rock Reservoir.  According to Bridgehunter.org the Bailey Bridge has a 152 foot span over the Kings River and lies at an elevation of 1,023 feet above sea level.

Bridgehunter.org on the Bailey Bridge

The Bailey Bridge is a Pony Truss design with a metal grated surface.





As industrial looking as the Bailey Bridge is it does have a somewhat ominous looking design which fits the motif for what is ahead on Blackrock Road.





Apparently this is how you leave messages for people when you're out camping on the Kings River with no cellular coverage.  Blackrock Road continues to the left over the Bailey Bridge while the road to the right follows the Kings River to Bear Wallow Camping Ground.


Balch Camp is only a short 3 miles to the north of the Bailey Bridge.  The signage on Blackrock Road is surprisingly good considering how remote it is.





PG&E apparently put these warning signs up on Blackroad Road.  Even the tame parts of Blackrock Road have a myriad of mountain based hazards.


As narrow as Blackrock Road is approaching Balch Camp this is probably the widest part of the roadway.  There is a surprising amount of vehicle traffic coming and going from the company housing in Black Camp.


Balch Camp is located the confluence of the North Fork Kings River and Dinkey Creek.  Traffic heading towards the Wishon Reservoir on Blackrock Road is directed over a one-lane bridge over to the west bank of the North Fork Kings River.



This bridge over Dinkey Creek shows an elevation of 1,360 feet.  This bridge is the beginning of Sycamore Springs Road which heads northwest.  Blackrock Road continues to the right through Balch Camp.


Surprisingly Balch Camp actually has a bypass road which loops past the community and the PG&E housing.  Past Balch Camp Blackrock Road crosses this large drainage pipe descending the cliff-face.





Past the pipe the asphalt quality of Blackrock Road drops considerably at this cattle guard.


An amusing "No Shooting near the Residential Area" sign on the opposite side of the cattle guard.


Blackrock Road briefly follows Dinkey Creek before looping back on itself back towards the North Fork Kings River.




Shoulders really aren't a thing on Blackrock Road.  My suggestion if you are in a vehicle is to roll your windows down and listen for noise.  You generally can hear engines off in the distance as there is PG&E trucks on Blackrock Road with surprising frequency.  If you hear something the best idea is to stop and find a place wide enough for two vehicles because you'll be backing up otherwise.


It might not be immediately apparent from the first photo but the cliff-face is a huge drop as evidenced by looking right towards the helipad on the opposite side of Dinkey Creek in the second photo.



This Slow Sign has taken a shotgun blast or two.


From the Slow Sign the North Fork Kings River and Balch Camp can be seen below.





Up ahead the first of two wooden deck bridges can be seen on the cliff-face.





The speed limit on the first wooden deck bridge is 10 MPH.  There is a indentation on the bridge showing it was completed in 1968.








The first wooden deck bridge makes it really apparent how steep the cliff above the North Fork Kings River and Balch Camp really is.






Things really don't get much better continuing north.






Approaching the second wooden deck bridge there was an opportunity for a panoramic which shows how the steepness of Blackrock Road above the North Fork Kings River.







Another 10 MPH speed limit is signed approaching the second wooden deck bridge followed by a sloppy "Slippery Bridge" spray painted poorly in the rock.






Again the second wooden deck bridge shows a construction date of 1968.







Ahead Blackrock Road drops to gravel/dirt past the Black Rock Reservoir.  I wasn't certain of the condition of the roadway north to the Wishon Reservoir but based off some videos I had seen prior to my trip it appeared to require high clearance at minimum.  I turned around having seen what I came for (easier said than done) and headed back to Balch Camp.








Information regarding the Black Rock Reservoir and it's construction history are scant to say the least.  There isn't much information out there regarding the topic, Balch Camp or even Blackrock Road.  Surprisingly the Black Rock Reservoir, Balch Camp and Blackrock Road are all shown the 1935 California Division of Highways Map of Fresno County.  Black Rock Reservoir is listed the Williams Crossing Reservoir:

1935 Fresno County Highway Map

The Black Rock Reservoir is located approximately 4,000 feet above sea level.  More information about Blackrock Road can be found on dangerousroads.org and fs.usda.gov.

In regards to the title of this thread, I just thought it sounded cool and I'm not aware of anyone actually dying on Blackrock Road.  The terrain of Blackrock Road on it's own merit is definitely the most difficult to deal with on any paved roadway in California I've been on.  Kaiser Pass Road probably is more difficult given the somewhat significant amounts of traffic it gets  in my opinion.  I ran into three vehicles north of Balch Camp but I was able to see them far enough away to be in a good position that it wasn't much an issue getting by.  That said, Blackrock Road isn't something that suffers people with vertigo or anything but skilled careful driving.

Trans-Sierra Highway Passes; Sherman Pass Road and Signed County Route J41

Probably the most unique Trans-Sierra Highway Pass I encountered in 2016 was the only one that isn't a State Maintained Roadway; Sherman Pass Road and Signed County Route J41.






Getting to Sherman Pass Road requires traveling deep in to Sequoia National Forest.  From the western Sierras the easiest routes are from California State Route 190 or from Signed County Route J22 east of CA 99.  When I was on my way to Sherman Pass I ended up taking J22 in Tulare County from CA 99 east on Sierra Avenue and Avenue 56 to Fountain Springs.  In Fountain Springs J22 has an eastern terminus but the road continues into Sequoia National Forest and through California Hot Springs as Mountain Route 56.





California Hot Springs essentially is a ghost town located at 3,081 feet above sea level.  California Hot Springs opened up 1882 as a health resort which grew into a small community with a shopping center.  The California Hot Springs Resort burned down in 1932 followed by the shopping center in 1968.  T…

Old 1916 Elkhorn Avenue Concrete Pony Truss Bridge

The other day I was browsing bridgehunter.com when I noticed that there an old Concrete Pony Truss bridge spanning the Fresno Slough in rural Fresno County near Burrell on Elkhorn Avenue.  Today I went out to the old span to grab some photos.






The Old Elkhorn Avenue Bridge apparently dates back from 1916 according to bridgehunter.com.

Old Elkhorn Avenue Bridge

I don't have an exact date for the replacement Elkhorn Avenue span over Fresno Slough but the old grade still has paint which makes it apparent the replacement probably was built in the last two decades.









As stated above the Old Elkhorn Avenue Bridge spans Fresno Slough.  Fresno Slough is a tributary connecting the Kings River to northwest to the San Joaquin River.  Before Tulare Lake dried up it would occasionally crest at about 210 feet above sea level which caused a back flow into the Kings River.  The back flow of Tulare Lake would in turn flow through Fresno Slough towards the San Joaquin River.  Today Fresno Slough rarely…

Legacy of US Route 466 Part 2; Tehachapi to Bakersfield

After completing California State Route 155 and CA 202 I found myself near Tehachapi Pass.  That being the case I trip back down to the Central Valley on CA 58 would have been mundane so I opted for the routing of US Route 466 to through Bakersfield.






This is the 2nd Part to the US Route 466 Legacy Series.  The first entry covered California State Route 46 and the overall history of US 466.

Legacy of US Route 466 Part 1; California State Route 46

The routing of  US 466 compared to modern CA 58 is substantially different from Tehachapi west to Bakersfield.  Heading westward US 466 would have diverged from CA 58 onto Tehachapi Boulevard passing through the community of Monolith before entering the city of Tehachapi proper.  Within Tehachapi US 466 turned south on Curry Street and west on Valley Boulevard.





Since I was on CA 202 I started my trek on the routing of US 466 at Valley Boulevard and Tucker Road.






US 466 diverged from Valley Boulevard and CA 202 at Woodford-Tehachapi Road heading …
