Westside Parkway and the Centennial Corridor; Future California State Route 58

After completing California State Route 43 I doubled back north to Stockdale Highway to check out a major highway construction project which will eventually reroute CA 58; the Westside Parkway and Centennial Corridor.


Currently CA 58 multiplexes CA 99 through central Bakersfield and uses the Rosedale Highway to continue westbound.  Eventually CA 58 will shift south off of the Rosedale Highway onto the Westside Parkway and Stockdale Highway once the Centennial Corridor is completed.  The Westside Parkway has essentially been completed since 2015 aside from the Centennial Corridor.  The Centennial Corridor is a 1 mile gap between the east end of the Westside Parkway and the current ramp junction of CA 58 and CA 99.  At present moment 99% of land parcels required to finish the Centennial Corridor gap have been acquired and construction of rerouting sewers has recently begun.  Information about the Centennial Corridor project can be found on the city of Bakersfield wesbite.

City of Bakersfield; Centennial Corridor Project

I drove the Westside Parkway on a eastern approach.  This picture of CA 43 and the Stockdale Highway is looking northbound.  CA 58 will traverse westbound straight ahead on CA 43 and eastbound on Stockdale Highway.


Once the Centennial Corridor is completed CA 58 will shift onto the Stockdale Highway and the city of Bakersfield will assume maintenance of the Rosedale Highway.  The Stockdale Highway is a fairly decent roadway and does have one rail crossing along the future CA 58 alignment.


East of the rails the Stockdale Highway widens out and the signage for the Westside Parkway appears.


Stockdale Highway traffic is directed to turn right heading eastbound while the primary traffic lanes enter the Westside Parkway freeway grade.



Currently there is no route shields nor exit numbers on the Westside Parkway.  I'm to understand that the mileage and exit numbers will follow what is posted on CA 58 east of CA 99.  The Westside Parkway is nice and has some nice bridgework designs that kind of emulate mid-20th century California Divisions Highways designs.







The Caltrans project sign denotes the beginning of the Centennial Corridor project.


Currently traffic from the Westside Parkway is directed onto Truxtun Avenue which has no access to the current CA 99/58 freeway.  Eventually traffic will continue southeast to the current CA 99/58 interchange.  I actually had to use Oak Street and California Avenue to join the current freeway configuration of CA 99/58.






Currently CA 58 east of CA 99 in Bakersfield is being reconstructed as well.  It doesn't seem at this time that there will be a freeway or expressway configuration continuing west to I-5 any time soon.  The CA 58 corridor has been a popular one for far flung projections about a western extension of I-40.  Personally I think with the Centennial Project and the recently built Hinkley Bypass that CA 58 ought to be adequate to handle traffic from I-15 to CA 99.  Really the only place I see as an issue is Kramer Junction at US 395 where a bypass route or expressway configuration has been needed for decades.

Did Caltrans just kill the G26 cutout US Route shields?

The US Route System was formally created by the American Association of State Highway Officials during November 1926.  Through the history of the system the only state to which has elected to maintain cutout US Route shields has been California.  The G26 series cutout US Route shields have become a favorite in the road enthusiast hobby and are generally considered to be much more visually pleasing than the standard Federal Highway Administration variant.  However, the G26 shield series appears to have been killed off on January 18, 2026, when Caltrans updated their Manual of Uniform Traffic Control Devices.  This blog will examine the history of the US Route shield specifications in California and what is happening with the 2026 changes.  The blog cover photo is facing towards the terminus of California State Route 136 and at a G26-2 specification US Route 395 shield.  In the background Mount Whitney can be seen in the Sierra Nevada range.   ...

Ghost Town Tuesday; Nichols, FL

A couple years ago I spent a lot of spare time exploring phosphate mining ghost towns in the Bone Valley of Polk County, Florida.  One ghost town in particular called Nichols on Polk County Route 676 west of Mulberry caught my eye due to a relative lack of documentation on ghosttowns.com. Nichols was created in 1905 during the early phosphate mining boom in the Bone Valley region.  For the time Nichols was unusual since it had company housing in the Nichols Mine site and private residences outside the gate.  Nichols is only about two miles west of Mulberry which probably made it a somewhat reasonable commute even by the wonky standards of the early 20th Century.  Most of the Bone Valley region was relatively remote which made commuting or homesteading impractical which is why there are so many ghost towns in the area.  The company housing section of Nichols was phased out and abandoned by 1950. The Nichols town site is largely abandoned and could "possibl...

Old Wards Ferry Road

Old Wards Ferry Road is an approximately 3.6-mile portion of the original alignment of Wards Ferry Road located near the city of Sonora, California.  As currently configured this older alignment begins at modern Wards Ferry Road near Curtis Creek and terminates in Sonora at Sanguinetti Road.  The Olds Wards Ferry Road corridor is largely defined by the single lane 1914-era arch concrete bridge at Curtis Creek. Wards Ferry Road is one of the oldest road corridors in Tuolumne County having been set up as a ferry crossing by Joesph Ward during 1850.  Wards Ferry Road was once the primary connecting highway between the communities of Big Oak Flat and Sonora.  Wards Ferry Road is most well-known from the largely one-lane wide alignment through Murderer's Gulch where it crosses the Tuolumne River via heavily graffitied 1971 Wards Ferry Bridge.  Pictured as the blog cover is the 1897 Wards Ferry Bridge as it was during 1951.  The 1897 Wards Ferry Bridge was built ...
