The most siginificant work is from the bottom at troutbeck.
The Howe was relaid with stone an appears to be stacked rocks from the bottom up. In effect a dry stone wall lying down on its side.
From Limefitt up to the cross roads there have been ditches dug either side of the trail to help keep the water off the trail and the trail itself has been graded to some extent though to say it was smooth would be pushing it. There is still an awful lot of loose rock on the tops.
From the crossroad up to the summit on the troutbeck side it is pretty much as it has been for the last couple of years. There are 2 areas where the dry stone wall has collapsed on to the trail higher up which I think has been caused by water coming down of the fell.
On the Kentmere side there have not been any significant changes as far as I can see in the last couple of years. the only ‘graded’ section is the hairpins about half way up but that has been the case for quite some time.
I would say it is entirely feasible to ride from the bottom at Troutbeck all the way to the summit without dabbing. From Kentmere? I am not so sure. I have heard of a couple of people doing it but both are very handy trial riders who are happy to trackstand and bunnyhop up steps most people wouldn’t even bother trying to ride up.
