Do old Truss Style Mast Arms still exist in IL.

Trusses, trusses everywhere, and a relatively new build location. I-55 at I-355

I'm not seeing any mast arms in that GSV shot...

I believe they meant the streetlights.

^ Trussed streetlights haven't gone out of fashion in Illinois.  They are still in the Highway Standards (see Pages 368/423 and 372/423)

Here's a classic example at 35th Street and Central in Cicero.  it even has the old 12-8-8 setup for the pole-mounted signals.

However, the MN like davit style streetlights have become more common throughout the state, even in D1. Again, I am not a fan of this style in Illinois. Downstate, outside of D1, the aluminum truss style has become even less common (maybe except in D8, where I have seen installations in the past 10 years become somewhat common again). That said, I am sure this thread was referring to the stoplight structures, which are basically a dying breed in IL, though, still, plenty of legacy installations, luckily, still exist.
