I guess sign replacement crews have a tendency not to look up, because the old font on these bridge signs indicates they're around 40 years old, and could even date to the first time overpasses were signed.
Way up in the northeast corner of Maryland, both are old but not button copy. The Chesapeake House link at the bottom of this page follows the blue sign into the service area, where more old signs await.
One more of these sneaks south of the Susquehanna River.
And drive across that river by clicking this video.
SB at Exit 64, a crazy crossover interchange where I-95 SB and NB switch, as well as I-695 inner and outer (inner, aka "EAST", is about to turn southward and then back westward across the Francis Scott Key Bridge). This means that all eight ramps only turn 90 degrees, and there is no weaving, but half of the entrances and exits are on the left, usually an unsafe practice. Well, I really just put this photo, courtesy Scott Colbert, here for the older I-695 shield on the left, and because I-895 doesn't come into existence until Exit 62.
As I take the southbound ramp to I-695, views of the future SB-EB flyover in the foreground curving next to the NB-WB flyover in the background. (In the third photo, they're left and right instead of foreground and background.)
Just south of Baltimore, first photo courtesy Lou Corsaro and button copy. I guess Washington is such a major destination that Richmond had to be wiped off the pull-through BGS. Obviously, MD 166 was the original Exit 47, and then when I-195 was constructed east to BWI, the existing signs were modified. Notice that the original destination of MD 166 South was U.S. Route 1 (just to the east), and that the original arrow wasn't good enough. Since the ramps weren't realigned, I'm guessing that the placement of the BWI logo necessitated the new arrow. With all the empty green space on the right of the sign, though, I don't see why this had to be.
All courtesy Lou Corsaro. The US 1 is tacked on. Gee, I couldn't tell. The I-495 signage is very similar to I-495 at I-270 - follow link at bottom. By the way, I-495 is Exit 27. Now you can sleep better.
