The San Diego International Airport changed the signs on 12 of its single-stall public restrooms about a month ago, according to U-T San Diego.

The new signs have individual drawings of a man, woman, baby and a figure that could be interpreted as half-man/half-woman.

The signs also say, "Anyone can use this restroom, regardless of gender identity or expression."

The single-stall restrooms with the new signs are in all the terminals at Lindbergh Field except the small Commuter Terminal.

The San Diego LGBT Weekly also has covered the new restroom signs at the airport, and in an opinion piece questioned if the symbols on the sign could be improved.
