As the title says, me and JPSC have made some road pieces that are 64x64. It includes the +, T, Straight, and curve. I also created a end/parking lot piece.
Every bit of it connects as well, great for making cityRPs.
The road also has a prebuilt sidewalk.
That white thing is a road raiser in case you want to raise up your city.
Anyways, on to the pictures and stuff.
Picture is the download, and yes it will open up as a text thing, just click the download button. (apparently mediafire thought it was a text document)

Feel free to use and such.
