It depends what company you're talking about. If you happen to be talking about the National Touring Productions SHN(Shorenstein Hayes Nederlander)'s Best of Broadway Series, their productions are as follows:
The 39 Steps December 9, 2009-January 3, 2010
Fiddler on the Roof Winter 2010 (Dates TBA)
In the Heights Spring 2010 (Dates TBA)
Young Frankenstein Summer 2010(Dates TBA)
West Side Story Fall 2010 (Dates TBA) Updated On: 8/29/09 at 10:40 PM
You can guess when some of the shows will run in SF by looking at their itinerary and seeing if there are gaps that correspond to when SHN says to expect the show. I'm guessing these might be the dates.
In The Hights - 5/11/2010 to 6/13/2010 Young Frankenstein - 6/15/2010 to 7/25/2010 or 8/17/2010 to 9/5/2010.
