SPUI Midpoint Signs

[jakeroot]

British Columbia uses a central island with...what are those signs called?

The technical term for it is an OM-3L, but other than 'hazard stripe marker' I have no idea what you would actually call this.

For NJ, I'm almost certain that there are no SPUIs in the state.

I've also heard them referred to as "tiger boards" or "tiger stripes."

I find the signs rather interesting because they are part of a select group of signs that are, for the most part, international.

"OM" = object marker, so I usually refer to these as "object markers," though that usage is technically an instance of synecdoche.

Are all the MD SPUIs signed with such a ghetto wooden sign?

No.

It looks completely unprofessional.

They tend to get struck pretty frequently.

Here in FL we don't usually sign the middle, but elsewhere (can't remember where) I've seen a raised diamond with a keep left sign.

I've seen those in at least two Maryland SPUIs.

I honestly don't remember anything on the one at I-71 & SR 665 but it's been awhile since I've been down there.

Nothing in the middle of that one. A while after it opened, they did improve that one by adding extension lines and black contrast paint on all the markings. It had been fairly bad, as the vertical curvature of the bridge makes it nearly impossible to see where you're supposed to end up on the other side of the intersection.

Kentucky calls them object markers.

No islands, object markers or synecdouches (?). The SPUI at I-25 Exit 101 and U.S. 50 West/CO-47 in Pueblo CO is marked on the north-west movement with large signs reading DO NOT STOP UNDER BRIDGE. Seems there is an intersection about 500 feet to the west that, if signal synchronization fails, can cause a backup into the SPUI intersection during the green cycle for the offramp.

Lots of interesting replies here. Regarding the original SPUI I posted, the bridge deck is quite arched. Why, I'm not sure, but it is actually pretty impossible for a motorist to see their destination across the intersection, so that may be why they have posted the large sign. You can actually see this in the photo, note the oncoming cars are not visible.

No barrier, just signs in the road.

That seems like a terrible idea.

And real close to the lane lines.

Room for error: zero...point...zero.

Man, that thing looks like it would get smashed all the time.

You can see the cardinal direction sign ("EAST") has been bent. Not surprising, of course. Also, the sign is leaning to one side, which I would think means it has been nudged previously.
