Something a little more sledding related from a lady local to our neck of the woods.   https://ski-doo.brp.com/ca/en/discover-ski-doo/original-series/iconic-sleds.html?bid=481451906&cid=DM310618&mvo=%40gy0riWxSKSNBplDjYCQzfQ%3D%3D                

Well, if the ditch increases in size, so must the culvert to match the flow rate, otherwise Houston we have a problem….. These adjustments in water drainage systems, aside from mitigating risks, is from what appears to be the extreme weather systems we have seen also in the last decade.  Im not sure if we receive more precipitation, but it sure does come down in much larger amounts at once then I recall it ever used too on more frequent basis.   

Culverts are bigger under drive ways too and more random cement culverts  to watch out for. I wouldn't ride a ditch I don't know, that's for sure. 

Deeper ditches=harder crashes!

I was thinking the same thing.......
