PENNY BRIDGE (3 PENNIES WIDE)
To do the Penny Bridge with a width of 3 pennies, do the same thing that you did for the 2 penny wide, except you put 3 pennies in the middle. With making the bridges with a larger span, put as many triads as there are pennies wide. Next, just fill up all the "spaces" between the triads, and keep going. Here is a penny bridge with the width of 3 pennies. It shows you how to build it in steps.
