Here ya go - the intersection at Northgate Way and Lake City Way in Seattle:

Lake City Way runs north/south, and splits at this intersection from a 
single- to dual-carriageway.  This intersection carries a stoplight for 
Lake City Way.  113th St enters both from the east and the west, but you 
cannot cross from one side to the other.  It enters the intersection via 
stop signs.  Northgate Way has a stoplight in the northeastbound 
direction, but not in the southwestbound.

How would ya do that one?  ;)
