Things you've always wanted to ask, but think it's not worth making a topic for

Only under Eleventh Avenue where the center tube is aligned where the north tube was after it submerges on the NE corner of eleventh and thirty ninth does it really curve.  The center tube is straight otherwise east of the NJ turn and between eleventh and tenth avenues. Both center and south make than same curve on the Jersey side so it should be pretty equal.

Note that it is impossible for the curve on the Jersey side to be the same length for both tubes as they are (roughly) parallel to each other (not on top of each other), and MC Escher did not design the tunnel.  This difference is, in fact, approximately 200 feet.

What is the Mexico equivalent to the MUTCD and why is it almost the same as the MUTCD but just different enough to annoy you?

Manual de dispositivos para el control del tránsito.  And it is not really similar to the US MUTCD--no real freeway signing scheme, for example.  The latest edition dates from 1986 and the basic stylistic features, such as the Mexican alphabet series (similar in appearance but not identical to the FHWA series) and the Aztec arrow, date from the 1960's at least.

Yeah , I have never thought the BGSes look similar.  More like the stop signs and yellow diamond signs.
