Our Rainbow Beam Bridge

We built a bridge using cardboard, lego, string, lolly sticks and tape. We tested it to see if it was sturdy by putting a toy car on and it didn’t fall down. We had to make the legs shorter because it was not stable. We added lolly sticks like a triangle for extra support. The lego was used as pillars to hold up the glass roof which is to shelter the vehicles or pedestrians from the weather.
