Problem of the Week #5

There is a railroad that spans a V-shaped canyon. It is supported by beams which start at length of 6 ft on either side of the canyon, while the next beam increases by 2 ft, all the way until the center of the canyon, where the middle beam is a length of 246 ft.

What is the total length of all the beams?
