phew. this site says its a 37% grade.
ah, other sources say, that 37% grade is only for 6.5 meters :)
SF has a couple streets that are 30%+ for nearly a full block. they are closed to traffic, however.
this street in SF is just over 31% for a 250 foot block, and was open to traffic in the 1950s :-O
and this street on Bernal Heights exceeds 37% for several short stretches,
