Mile markers every 1/10th of a mile - Yes? No? Sometimes?

NJ posts every 0.5 on major routes (US 46, NJ 17). Freeways usually get every 0.1, but in no case are they too-well maintained. Parkway and Turnpike maintain theirs. All are the small 2' style with 4" numbers no one can read.

Let's not forget that we have some weird state route situations with .1 of a mile markers (167, 171, 157, 13, 32, 162, 64, etc.)

Weird NJDOT logic for whatever reason, considering most of the above listed ones are pretty pathetic state routes.

Though they can probably be read pretty well if you happen to be stopped because of a breakdown or crash.  And I've always been able to read the ones on the Turnpike, at least along the four-lane segment in South Jersey.

Massachusetts used to show their 1/10th mile markers with a small grey or yellow diamond that had the mile number placed above the 1/10th.

The 1/10th markers were yellow diamonds.  As these older intermediate markers were placed for plaiing and maintenance purposes, and were never intended to be used by drivers for location identification or navigation, they were only 4 inches by 4 inches in size.

One tenth marker along MA 114 (Lafayette St.) in Marblehead uses a grey diamond (MM 21.5 IIRC); just before the Pleasant/Humphery St. intersection (aka Tent's Corner).  And I have seen grey diamonds used on other Bay State roads.

I think that the I-95 milemarker signs have shields through metropolitan Richmond (Hanover, Henrico and Chesterfield Counties and the City of Richmond).

Richmond and Chesterfield don't. They just have the old-style markers every mile.

Thanks for pointing that out.  I was certain those signs extended south of Henrico.

I drove all of Md. 404 (Queen Anne's, Talbot and Caroline Counties) yesterday, and doing so reminded me that Maryland SHA has posted markers every half mile between the Delaware border and U.S. 50.
