select each face and press one of the align button (L,R,Fit | T,B,C): that is Left, Right, Fit, Top, Bottom, Center. Depending on the orientation of the brush, usually aligning to Top works. Make sure you don't select "Treat as one" and don't select either "World" or "Face align. You need to have texture lock on when you create the arch to keep the face orientation.

You can also select a face and hold alt then right click on a face to apply and align it with the selected face. This doesn't work around curves, but it can align perpendicular to them.
