(April 2000) Lafayette, IN. Current style Interstate signs have the numbers as big as they can be.
This appears to be a new interstate sign with the state name. Signs with "INDIANA" are quite rare on the road (Photo by Joe Koehler).
Indianapolis, IN. Another interstate sign with the state name. Perhaps the fact that this sign is mounted on a traffic light mast arm has kept it from being replaced. (Photo by Joe Koehler)
Indianapolis, IN. Is AASHTO adding suffixes to Interstates again? No, I-65 and I-70 run concurrent through downtown Indianapolis with a flurry of ramps. This sign directs the traveller to the ramp leading to I-65 SOUTH and I-70 WEST (Photo by Joe Koehler).
Indianapolis, IN. Another split route sign (Photo by Joe Koehler).

Another embossed US highway shield. Note that this sign has a slightly smaller "INDIANA" than the sign above. (Collection of Robert Edgar).
Not really US-249. Not only did the sign shop make a VERY sloppy sign, it also used the wrong sign blank. The route should be IN-249. (Photo by Joe Koehler)
(April 2000) Current style of Indiana route markers. Indiana converted its state-shape signs to this style back in the mid-50's.
(April 2000) Three-digit routes use an extended 36" sign.
(April 2000) State route signs on big green signs are identical to free-standing signs.
This sign is kind of a mystery. According to owner Joe Koehler, this is an Indiana sign - if so, it might be an interim sign between the current style and the older map style.
(Summer 1976) Original Indiana state route marker. Like Illinois, Indiana used a map on its state route signs. However, Indiana did not carry the design over to flat signs of the 1950's like Illinois did. This style was retired in the late 1940's. This particular sign was photographed, still in service, in 1976 by Michael Summa.
(February 2000) New Buffalo, MI. Yes, you read the location correctly. Indiana places its toll trailblazers in neighboring states. This is an older trailblazer that still uses the 'E' and 'W' for East and West. Indiana had planned a North-South toll road, but that was scrapped with the advent of the Interstate system.
