Needs junction details but it looks like more budget cycle infrastructure. Without time at lights and protected junctions it's not really that much. Covers a really small part of that "route" as well
I've seen some (not yet public) slightly more detailed plans for one of the junctions and it includes time at lights and decent protection. Hopefully that'll be repeated everywhere.
New Cycleway 50 on Seven Sisters Road (etc) in Islington to go in this year:

It'll eventually link up to the Camden Square and Royal College Street route into town.
