US 98 seems to have concurrencies with every major route here in FL. US 90, US 319, US 19, FL 50, US 301, FL 60, US 17 and US 27 have all shared pavement with US 98 at some point between the Alabama state line and where we are now. US 98 south is now concurrent with FL 70 east here in Okeechobee FL. US 98 will split 2 miles away in downtown to join US 441 along Lake Okeechobee and all the way out to the suburbs of West Palm Beach. When US 98/441 leave the Lake Okeechobee area in Belle Glade, FL 80 hops along all the way to the end of US 98 in Palm Beach.

...one route has a number with a 8 in the tens place, and the other route has a number containing a 9 in the tens place.

I don't take a lot of sign photos so I'm not in this thread much.  I have the Nevada I-580/US 395 concurrency in Carson City, from the community open house held on July 22, 2017.

US 98 merges with US 90 eastbound for about 2 miles to bypass downtown Pensacola FL (which is served by US 98 Bus). US 98 will rejoin it's bannered counterpart not far from the beginning of the Pensacola Bay Bridge.

A weak ending of the season for me, with just one truly new one and one rerun that duplicates the routes from the first post of the day but at least is a different concurrency of those routes.

I-94 and Minnesota 95 in eastern Minnesota.  July 31, 2010.

That concludes the concurrency extravaganza! Season 10 is wrapped! On September 1, we begin Season 11, which focuses on the ones digits found on expressway exit signage. We will consider the number of the destination route that appears on the sign, and the number of the exit.

September 1: Post exit signage showing that the exit number and the number of the destination route both end in 0.
September 2: Post exit signage showing an exit number and a route number for the destination route, where one of these numbers ends in 0 while the other number ends in 1.
September 3: Post exit signage showing an exit number and a route number for the destination route, where one of these numbers ends in 0 while the other number ends in 2.

Don't be surprised if I am late posting my photos from September 1 and September 11. I will be on vacation.
