Model bridge Answered

Hello, 
           What is the best way to construct a model bridge out of small wooden icecream sticks
 The requirements are as follows:
1) the icecream stick dimensions are 2mm deep 10mm wide by 115mm long
2) the bridge has to be 1 metre long and about 20-30cm wide
3) the only materials are the wooden icecream sticks , wood glue and cardboard to form the deck of the bridge.
The idea is to construct the bridge so as to be able to hold the most weight.The most weight achieved so far is 450 kg before breaking
