Nevada probably has the most, due to how wide their roads are. Harmon & Las Vegas Bl comes to mind.

Note: Keyword is 'cantilevered'. Traffic lights on bridges do (https://goo.gl/maps/exu5P) not (https://goo.gl/maps/5QvwZ) count (https://goo.gl/maps/Trizc).
The one at Glebe Road and Jeff Davis Highway (US-1) in Arlington, Virginia, has always seemed like a very long arm to me. It's the one directly ahead of the camera's viewpoint here.

The new ones on John Young Parkway between Sand Lake Road and the Beachline in Orlando are pretty long spanning six lanes of traffic. Big fat monotubes to do this, but still an arm by definition.

Holy shit. Seems overengineered, even for a hurricane area.
So far, looks like 7 signals is the max, but that mast-arm might be longer.

What's with the 'yield to left turns' sign there - is the opposing left permissive only? Doesn't look MUTCD compliant.
Going on a slight tangent from the original topic, what are the longest mast arms per state standards?
* Illinois is 75' (from the statewide highway standards (http://idot.illinois.gov/Assets/uploads/files/Doing-Business/Standards/Highway-Standards/PDF/216-877002-02_SteelMastArmAssembly&Pole56%27thru75%27.pdf))
* Minnesota is 80' (per Page 6-77 or 341/456 of the Traffic Control Signal Design Manual) (http://www.dot.state.mn.us/trafficeng/publ/signaldesign/2014signaldesignmanual/2014_Signal_Design_Manual.pdf)
* Utah is 85' (from Page 12 of the Signalized Intersection Design Guidelines) (http://www.udot.utah.gov/main/uconowner.gf?n=13679121470326565)
Does any state have any greater lengths?

I wonder if a u-turn is considered a left turn here.

There's a no u turn sign as well for the direction that would be into those lanes.

NJ apparently has suppliers approved to provide arms up to 65' in length. The standard arm they use: the trombone, is permitted up to 25 feet, per their sheets (I swear I've seen longer though).
