I see that CRT will shortly be escorting boats through a short length of the South Oxford summit while the HS2 people construct a temporary bridge over the canal. It's over two years since we were up there and saw the mountain of earth all ready in place to lift the line up over the canal.
They'll have their work cut out escorting all the boats because it gets a lot of boat traffic up there, including a lot of hire boats at this time of the year. No doubt the temporary bridge is needed so that they can work from both sides to prepare for the real bridge. I wonder when that'll appear. I suppose there will be a lot more of this to come because the line will cross the canal in a number of places including a huge flyover near Denham on the GU.
