Cajon Blvd/old US 66 abandoned lanes

[SeriesE]

From satellite images Cajon Blvd/old US 66 was a divided highway with 4 lanes from I-15/I-215 to Cleghorn Road. any reason why 2 of the lanes were abandoned throughout the area?

Presumably because traffic counts don't demand a 4-lane road and therefore no need to keep paying for maintaining it as one.

A lot of old US 66 in Illinois has had this happen to it - https://goo.gl/maps/tQNzJZYavyLtsaS58

Old US 66 in western Oklahoma has a section like this - https://goo.gl/maps/bRVBW4uiUCyTMNUE9

Old US 17 in lower SC - https://goo.gl/maps/QLRZRMtzYxRqPHfc8

A similar thing happened with US routes in the Dakotas that were usurped by interstates, except they weren't ever 4-lane.  The state has declined to keep them as paved roads.

The irony is nowadays the traffic is probably high enough to justify all four lanes being maintained.  More so now that Cajon Boulevard is no longer severed with direct access to San Bernardino.

Cajon Blvd would have to be rebuilt where it goes around the I-15/215 interchange. Though it would probably be enough for now to just restore the four lane sections of Cajon that still exist and wait to see if traffic justifies a full four-lane Cajon.

I went through there a few weeks ago, when I-15 was very crowded, and I had never seen so many cars on Cajon Blvd. These weren't US-66 hunters, they were commuters.

There appears to be room to widen the new section under I-215. But there would still be a bottleneck at Cleghorn (not to mention on I-15 between Cleghorn and CA-138). It's interesting that when they built I-15 they dug up the old NB side of US-66 approaching Cleghorn, but you can still faintly see the scar of that road (more easily in the 1994 GE imagery).

If anything it illustrates that the redundant nature of Cajon Boulevard had long term value and shouldn't have been neglected.  I wish something similar was available via Piru Gorge north of Castiac on I-5.

Totally forgot about the maintenance angle. Given that a lot of "maintained"  roads were crumbling, I thought there's no significant cost to keep them open but not actively maintain them.

San Bernardino County doesn't exactly have a stellar record maintaining its own road network.  It is in keeping for the County to defer maintenance on an older road like Cajon Boulevard until it becomes unusable.

They did the same thing with the old Golden State Highway that parallels I-5 south of Pyramid Lake.  Most of the four-lane has been restriped to two-lane.

Both ends of Pyramid Lake no less.  Shame it's bisected now by a reservoir, it would be handy during back ups.
