Do old Truss Style Mast Arms still exist in IL.

<< < (2/6) > >>

ILRoad55:
There's 2 at Ogden and Saratoga, but the signals have been replaced so they aren't positioned like the originals anymore. Those mast arms are also used for the Middle turn lane only signs along Ogden too.

Cass and N Frontage Road have all 4 mast arms. Again, it uses newer signals though. Route 53 in Bolingbrook uses them too.

I recall 75th had some truss mast arms but I think they've phased them all out. I also remember 75th had another unique mast arm design. It was bulkier and had goose neck lamps. I think the only one left is at Modaff and 75th in Naperville.

Alright so first post lol, I've honestly been lurking and hoping for someone to bring up this thread. I honestly can kind of get why they're getting put out of use, but I think these truss arms are way better than anything IDOT's putting up nowadays if you ignore functionality.

There's one I found on Google Maps maintained by the state in Taylorville, it lasted long enough for someone to put the fancy reflective tape on the backplates and everything.

There's another one over in Homewood on 183rd by Kedzie. It's weird because they put two overhead signals on the truss instead of a supplemental one on the right. I've only seen a couple other instances of this, one in Matteson, but most of the time they only put one overhead signal on the trombone truss.

Finally, if you look at old pictures on Google Street View, you can see a trombone truss with the correctly mounted signals, with an overhead 12-8-8. The truss arms are still there, but they used brackets to mount new LED signals onto the truss.

They were a lot more common, even when I was growing up in like 2006. I distinctly remember being displeased that they replaced the trombone trusses at 167th and Oak Park with more common assemblies. It's a shame that they aren't actually trying to put the signal on correctly either; in southern Illinois at similar intersections they still hang the signal directly from the trombone truss. I think brackets look tacky, especially when they don't get the new signal all the way to the end of the arm.

Skokie & Dempster (in Skokie) has four black truss-style mast arms. They look surprisingly clean. The signals were replaced within the last ten years.

Obviously based on my location, I am not from Illinois. But I remember marking this intersection/signal on Google Maps as I liked how it was setup. Very clean, good placement, and I like the truss-style mast arms. I was shouted down for my opinion as others indicated there were not enough overhead signals, but I always thought those were overrated anyway :)

Mod-note: I think this may be better in 'traffic control'?

Only if it starts to become a wider discussion on unique signal mast arm types. Otherwise, this is probably just an Illinois thing.

And I'm sorry. I didn't realize we were only looking for the original mounts.

Here's a set of three in a row, two of which are on an IDOT road* that as a kid, I never liked the look of for some reason. These signals were updated a few years ago now, so they no longer stand. Also note the use of backplates on the 12-8-8 ground-mounted signals, something extremely unique even back then.

* IDOT doesn't maintain the section with the first one, despite them all being relatively close to one another. It's complicated.

Those "Goose Neck" arms were a DuPage County thing in the 1990s I believe since I never saw one out of the county.  75th has a few still. Naper-Plainfield Rd (partially) and Modaff Rd.  The ones that were in Darien got taken out with the reconstruction of 75th last summer. Pretty sure DuPage County is phasing these out now.
