Today is March 14. Or, written another way, 3/14. That makes today "Pi Day."

Pi, which has an approximate value of 3.14, is used to find the area and circumference of a circle. Pi has many applications and engineers at ADOT certainly use it when designing and building the state highway system.

Though most people are familiar with 3.14 being the value of pi, its full value can be calculated to trillions of digits. Here at ADOT, we wanted to mark Pi Day with something fun. So, we went to the 50th digit of pi, found photos with those corresponding digits on our highway signs and edited it all together with a catchy song.
