Curved grade crossings

[Old 'n' Weary]

I'm putting some roads onto a layout that I bought, and it would make my life much easier if I could find some premade curved grade crossings in 18", 20". and 22" radius. Can anyone help? Thanks.

you can cut out card stock or plastic ( in my case i used hydrocal) to pave over the tracks. there aren't any curved grade crossings i'm aware of.
