Roads in perspective. Bended pathway road curved city street

I purchased a listing for 7 roads, thought I was going to be getting 7 separate files for each road. The purchase came as 1 file with all roads in it. The image eludes to the file being a png with transparent background, but it is not, the purchase is a jpg. Yes, if I had looked closer at what was listed as the output, I would have realized that. I was able to salvage the purchase by importing into Photoshop and cropping out the files that I need, but it was a bit more work than I thought I was purchasing.
