Problem with flipped object attached to the spline

During the class today, with your help, we managed to fix the problem with the flipped object attached to the spline! Hooray!

I worked on the word "SLOW" and looked up for some tutorials of how to model a path or a road today at school. My idea was to create a road by making a path and then add the road texture to it later. First, I create 2 splines that define the edges of the path or the road but I couldn't join find the tool that join the 2 splines together in order to make a path. It took me really long to play around and try to figure out how I could achieve the result I wanted. I kept searching for more tutorials on how to create a simple road but I found a lot of pre-made 3D roads which I don't want to use for my project.

I became more and more frustrated during this project because I know that I want to create but I couldn't make it happen.
