I looked a couple times but didn't see it mentioned, is it in conduit already? For just 30' I'd consider digging down at each end to the ell or LB, cut it so it's a straight shot and pull new cable in the existing conduit with lots of wire lubricant.
Worked okay with running a new feed to my shop.
YMMV
