Single White Centerline on Rural Two-Lane Two-Way Road as of 2016

Davis, OK
Google Maps shows the City Limits running down this road, so IDK if the city or county maintains it

I know years ago Park Roads used that instead of the standard yellow lines.  Skyline Drive in Shenandoah National Park, and even the whole length of the Blue Ridge Parkway in VA and NC used to use a while line in the middle.

In NJ Union County used to use the single white line on roads maintained by them in the county parks, especially Watchung Reservation.

This is so odd to still see this so recently.

Most roads like this in Oklahoma are left with no stripe at all.

Most roads like this in Oklahoma are left with no stripe at all.

A lot of county roads like this in Texas are like that as well. Even some of the more heavily-traveled ones that are required to have one

Woodbury, NJ fairly recently did a single white centerline on side streets approaching the main roadway (which in this case is also under their jurisdiction).  https://goo.gl/maps/WYGUhuzebP82 .  Why they would do this is anyone's guess, as they otherwise know how to do it the correct way.

Not exactly related, but "hurricane bridges"  (the quickly built replacement bridges alongside destroyed bridges) were often only painted with a single white line. My mom drove the pencicola bay bridge after a hurricane, and has seen it. I assume it's just because white is cheaper than yellow, and the bridge is only going to be up for a short time.

There are two streets in Tacoma, WA with a white center line, left over from before the MUTCD changed (whenever that occurred).

N Yakima Ave (street that the "The Hand That Rocks the Cradle" home is on) -- still fairly bright in areas: https://goo.gl/i18E8Y

E 25th St -- really worn down (easily one of the worst streets in the city): https://goo.gl/Z83rDX

There's at least one left in Seattle. Delmar Dr E has a white center line only in the curves, but is overlaid by dashed yellow lines: https://goo.gl/6Zyzcw

In the '50's and early '60's a number of towns in CA's Orange County featured single white lines as center delineators.  Most of these were in towns such as Midway City (one of my uncles lived there), although I do remember others closer to the beach (in the yet-to-be-developed Huntington Harbor area).  Most of these had been replaced by standardized pavement markings by the mid-70's, although a few pockets, adjacent to or near Midway or the north part of Huntington Beach, persisted until about the end of the decade or until new housing tracts were deployed in the vicinity.  One of the more odd and unique pavement markings associated with the single line was the approach to stop signs, where a squiggly line (like a sine wave on an oscilloscope) was laid atop the center line as a warning that a stop sign was imminent.  Those didn't last as long as the single lines themselves; don't remember seeing any after about '63 or so.
