Sunday streets -belated closure warnings

Sorry I didn't look this up before hand, better late then never? yeah I know, this is probably too late:

From DOT:
Route: 7th Avenue from Central Park South to 42nd Street; 42nd Street to Westside Highway (9A); Westside Highway to West Thames Street:
The above streets will be closed Sunday from 6am to 11am for the NYC ½ Marathon as permitted by the Mayor's Street Activity Permit Office (SAPO).

Formation: Madison Avenue and East 41st Street
Route: Madison Avenue from East 41st Street to East 27th Street
End: Madison Avenue at East 27th Street
The above streets will be closed Sunday from 11am to 6pm for the Indian Day Parade as permitted by NYPD. Also the Festival will occur on Madison Avenue between East 23rd and East 26th Street as permitted by the Mayor's Street Activity Permit Office (SAPO).

Madison Avenue between East 42nd Street an East 57th Street: This street will be closed Sunday from 11am to 6pm for the Workmen's Circle Street Fair as permitted by the Mayor's Street Activity Permit Office (SAPO).

In other words: Madison Avenue will be or is closed from 23rd all the way to 57th. Parades make it hard to cross, but at the street fair from 42 to 57th it may be easier with still some slowness.
