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.

Hidden California State Route 710 and the Pasadena Gap in the Long Beach Freeway

Infamous and the subject of much controversy the Pasadena Gap in the Long Beach Freeway has long existed as a contentious topic regarding the completion of Interstate 710 and California State Route 710.  While the Pasadena Gap of the Long Beach Freeway effectively has been legislatively blocked the action only came after decades of controversy.  While the Pasadena Gap of the Long Beach Freeway is fairly well known what many don't know is that a small segment was actually constructed south Interstate 210 and the Foothill Freeway.  This disconnected segment of the Long Beach Freeway exists as the unsigned and largely hidden California State Route 710.  On June 29, 2022 the California Transportation Commission relinquished California State Route 710 to the city of Pasadena.  The blog cover above depicts a southward view on the completed Pasadena stub segment of the Long Beach Freeway which ends at California Boulevard.   Part 1; the history of the Pasadena Gap of the Long Beach Freewa

Deer Isle Bridge in Maine

As graceful a bridge that I ever set my eyes upon, the Deer Isle Bridge (officially known as the Deer Isle-Sedgwick Bridge) surprisingly caught my eye as I was driving around coastal Maine one Saturday afternoon. About 35 miles south of Bangor, Maine , the Deer Isle Bridge connects the Blue Hill Peninsula of Downeast Maine with Little Deer Isle over the Eggemoggin Reach on ME 15 between the towns of Sedgwick and Deer Isle . It should be noted that Little Deer Isle is connected to Deer Isle by way of a boulder lined causeway, and there is a storied regatta that takes place on the Eggemoggin Reach each summer. But the Deer Isle Bridge holds many stories, not just for the vacationers who spend part of their summer on Deer Isle or in nearby Stonington , but for the residents throughout the years and the folks who have had a hand bringing this vital link to life.   The Deer Isle Bridge was designed by David Steinman and built by the Phoenix Bridge Company of Phoenixville,

Paper Highways: Proposed US Route 66 Alternate to Las Vegas, Nevada

During February 1956 the State of Nevada in concurrence with the States of California and Arizona submitted a request to the American Association of State Highway Officials to establish US Route 66 Alternate to Las Vegas.  The proposed US Route 66 Alternate would have originated from mainline US Route 66 in Kingman Arizona and followed a multiplex of US Routes 93-466 to Las Vegas, Nevada.  From Las Vegas, Nevada the proposed US Route 66 Alternate would have multiplexed US Routes 91-466 back to mainline US Route 66 in Barstow, California.  The request to establish US Route 66 Alternate was denied during June 1956 due to it being completely multiplexed with other US Routes.  This blog will examine the timeline of the US Route 66 Alternate proposal to Las Vegas, Nevada. The history of the proposed US Route 66 Alternate to Las Vegas, Nevada On February 15, 1956, the Nevada State Highway Engineer in a letter to the American Association of State Highways Officials (AASHO) advising that six c
