From the Queens Times:
Once again New York City hosts the circus, and the popular parade of elephants will be making a grand entrance via the Queens Midtown Tunnel just before midnight on Monday, March 23rd. Motorists should use alternate routes during this period (from 11:30 PM); the tunnel is expected to re-open at approximately 2 AM, Tuesday, March 24th.
A total of ten Asian elephants, nine horses and three ponies, along with animal trainers and escorts, are coming to Manhattan to appear in the Ringling Bros. and Barnum & Bailey Circus.
The annual “elephant parade” route is through the north tube of the QMT. The circus entourage will exit the tunnel in Manhattan and make its way westward across E.34th Street to Madison Square Garden, where the show runs from Sun., March 26th through Mon., April 13th.
