CA 25 Airline Highway
« on: October 19, 2017, 11:49:48 PM »

Did the full route of CA 25 from CA 198 north to US 101 this morning.  I even stopped to get some extra pictures of the original alignment on Lewis Creek Road, I'll probably have a road blog up this weekend:

I've been working on a new blog for CA 25 on Lewis Creek Road.  The Lewis Creek Road alignment of CA 25 was active from 1934-1953 when maintenance was swapped with Peach Tree Road through Lonoak and Peach Tree Valley.  Interestingly I can't find any information on the transfer of CA 25/LRN 119 from Lewis Creek Road onto Peach Tree Road on any CHPW guide, it just kind of just appears on the 1954 Division of Highways Map.  Lewis Creek Road is notable in that it had numerous fords of Lewis Creek and has to be among the most haggard roadways ever maintained by Division of Highways.  At some point after 1954 part of Lewis Creek Road became a private reserve and the former south terminus of CA 25 at CA 198 near Priest Valley is gated off.  These maps below highlight the early alignment of CA 25 on Lewis Creek Road, I used a 1944 Topographical to highlight any fords of Lewis Creek that have been eliminated:

Something interesting I noted looking back at the CA 25 blog; for some reason the Division of Highways moved Lonoak from Monterey County to San Benito County in the 1950s.  That being the case, the alignment of CA 25 actually swapped circa 1955.  I have no idea why the Division of Highways changed their location of Lonoak, it is well established to be in Monterey County.

I might have found the driver as to why CA 25 was moved off Lewis Creek Road.  Apparently there was some major storms that hit the Diablos in December 1955 that destroyed sections of numerous highways.  The CHPW guides don't outright state it but I found find it improbable that Lewis Creek Road with dirt fords would have held well if at all during a major storm:

CA 25 north of CA 198 to the San Benito County Line shows up on the 1957-58 budget to be surfaced.  This would be the post 1955 alignment on Peach Tree Road through Lonoak:

Looking at the current T intersection with Lewis Creek and Peach Tree Road, was there ever a time where 25 continued straight on towards Lewis Creek rather than directly south into Peach Tree?  (I'm reminded a lot of when we had those threads here about US 466 between Route 41 and US 101 where it took a mostly-abandoned route from Shandon to Atasacadero that still has evident right of way, including an abandoned bridge entering Atascadero near Rocky Canyon Road and Sycamore Road, and former right of way northeast of Route 229 in Creston)

From every topographical and aerial map Iíve seen it looks like the T intersection has always been there.  Even the 1935 Division of Highways Maps shown the T intersection present.  It kind of even begs more question what the point of adopting LRN 119 onto Lewis Creek Road when Peach Tree Road pretty already existed in a similar manner to it does now?

I made some substantial updates to the CA 25 Airline Highway blog.  The segment of 1934-55 alignment of CA 25 on Lewis Creek Road was heavily expounded up from what was originally posted.  While no volume of the CHPW guide outright states the reason it seems that floods in December 1955 heavily affected CA 25/LRN 119.  It is highly likely that CA 25 was moved via maintenance exchange with Monterey County to Peach Tree Road after Lewis Creek Road was likely heavily washed out.  Lewis Creek Road as part of CA 25 was very unique given it included numerous earthen fords of Lewis Creek.

So, San Benito County does have money to invest in something infrastructure related after all.  Kind of makes me wonder if they would be so willing if it was actual construction?

Glad to see they're finally spending money on CA 25 northwest of Hollister.  They've been squabbling with Caltrans and amongst themselves over the CA 25 widening for decades.

Iím kind of surprised myself, San Benito County tends to be extra stingy investing anything into road projects.  The county road network is probably in the roughest shape in the entire state which is why I was surprised to see them throw in money towards a Caltrans project.
