i made a quick design for bridges. saw this on modern marvels how the pieces connect and all. so i decided to do this. its good for making huge bridges to connect places.

just had little fun(car bomb)

you cant tell but the Vehicle is in a hole in the bridge

hole in the bridge as you can tell underside

how big the bridge goes(as long as i could get it across the bedroom

side view of the bridge section

if you see the lighter grey, there is 2 holes used for connecting. this is how the bridge parts connect

this is the part that holds the bridge in place
if you like the idea of this its not hard to do this i might redesign it so its not a lot of bricks but for right now it is nice i guess
