How do I climb the Broadway church?

I have been trying to collect all of the Fast Travel bonus boards in Forza Horizon 4, which will allow me to use the Fast Travel feature for free. Most have been easy, but I recently spotted this one on top of a church in Broadway, on the south side of the map, and can't figure out how to reach it.

I've seen a few other bonus boards located on top of obstacles, but none were this high, and they all had some obvious ramp-like feature nearby to jump from. There doesn't seem to be anything like that near the church.

How do I obtain the Fast Travel bonus board on top of the church in Brodway?

The ramp for that board is actually a danger sign jump.

The jump, from your picture location is directly to your left just behind some trees in the middle of a grassy (or snowy during winter) patch.

You need to reach a certain rank in order to unlock the jump, I think it may be rank 5? I am not sure if it shows up until it is unlocked, it is a standalone ramp (not part of the map itself).

Unfortunately, until then, it is not possible to reach that fast travel board.
