State-Unique Sign Bridges in Other States (that don't share the same specs)

Here's a couple.

ODOT gantry in California.  Presumably built and maintained by ODOT since it houses a VMS that's only a few miles from the border.

Here's an ODOT style sign bridge deep into Washington. 

I know a lot of freeways have artistic themes and many will use monotubes that are rare in the state.  For example, US-75 through Dallas uses prism monotubes similar to WSDOT.  I rather this thread not focus on themed gantries.

MN-style gantry on I-535 in Superior, WI, although I wouldn't be surprised if MNDot installed that themselves anyway.

There's a Tennessee gantry on the Purchase Parkway just north of the Kentucky state line.

I guess ODOT also does that in Washington.

It's an ODOT monotube (braced) yet follows WSDOT specs.  The streetlights & signs on the bridge are definitely ODOT.

It doesn't surprise me one bit that ODOT installed a VMS to display Oregon travel information and/or advisories.  Besides, I don't believe Caltrans has a VMS north of Yreka.

The NJ Turnpike used to used designs similar to Caltrans freeway gantries when the road first opened.  The old art deco signs that were once used on the Newark Bay Extension and at Exit 6, were used around LA on some freeways back in the 70's.

Ohio typically uses truss bridges, but in the vicinity of the Maumee River bridge on I-280, everything is white monotubes: https://www.google.com/maps/@41.658242,-83.510054,3a,75y,148.92h,84.99t/data=!3m4!1e1!3m2!1sbFCrC-pCA8GF98hunZN79Q!2e0

Then there's this thing in Buffalo, NY that looks kind of like a Connecticut bridge: https://www.google.com/maps/@42.884523,-78.880168,3a,75y,167.21h,89.87t/data=!3m4!1e1!3m2!1sasqxJcIxSabrwdoG-si69A!2e0

I won't even mention the monotube that went up on the Thruway recently...

The DRBA adopted the VMS sign trusses the NJ Turnpike uses for their new VMS signs; 4 out of the 6 are in Delaware.  There's one in each direction that has a VSLS as well (not sure why they didn't put the VSLSs next to all their VMSs).

Hmm, button copy. Not a lot of that left in Washington.

Illinois has a few different types of sign bridges.

1. IDOT usually uses square truss sign bridges.


2. IDOT went through a phase in the 1980s and 1990s where they used the brown sign bridges, most prominently in District 1 (Schaumburg).


3. ISTHA uses triangular truss sign bridges (with the exceptions of a few near toll plazas) and monotubes for I-Pass equipment.


4. CDOT uses monotubes along the Chicago Skyway.
