In The 1st month of this year(the year 2013), I noticed that the date 13-1-13 (13 January 2013) is special.

A car is crossing a 20 km-long bridge. The bridge can support at most 1500kg of weight over it. If somehow, the weight on the bridge becomes more than that, it will break.

Can you tell if the bridge breaks at this point or not?
