Although not signed correctly, unsigned FL 25 & FL 35 approach from opposite directions along the US 27/US 301/US 441 corridor in Belleview and depart in unison to the east along a short wrong-way concurrency. 8 blocks away, the two routes split, with FL 35 heading north to Silver Springs, and FL 25 becoming CR 25 and meandering around Lake Weir back to Lady Lake, to meet back up with US 27/US 441. This 8 block stretch is the only segment of FL 25 in the entire state to be signed, with everything from Belleview north to Jennings and Lady Lake south to Miami being hidden routes of US 27, US 41 or US 441.

New York 28 and New York 30 share two concurrencies, over 150 miles apart, via 30.  This one is in Margaretville, in the Catskills, taken January 12, 2022.  The other is in Blue Mountain Lake in the Adirondacks. It's about 40 miles longer to use New York 28 between these locations.

It's spelled "Zillah" right there on the sign, and that is the correct spelling.  My wife grew up in nearby Sunnyside.  She says I mispronounce most of the town names in the state, including "Yakima".
