No trouble. The straight sections are 16" wide, overall width is 81". There are two sections of straight on each side, a long and a short. One 90" and one 84" total length of straight is 174". The corners are 22" wide at the apex. Total overall length is just over 22'. The edging is some sort of hard plastic that one of the guys found in his home when he moved in. I think it came in a 4x8 sheet and we rip it down. It happens to be the same width as the slot and we use it to route the second and third lanes. I have also used coroplast on several tracks. It is the stuff yard signs are made from.
I have to give lance the credit on this track, he build it and just recently I sold my banked oval and we brought his track over to my place while I build a road course. The big mess in the picture is due to me adding the pit lane.
