Based on that image yes they are.
Based on activity near me (Northumberland) there’s 3 types of activity you can see:
Fixing blockages
Installing cabinets and underground chambers
Microtrenching the individual streets to enable access to each property.
I’m not sure on the timescale as our neighbouring town is smaller but was done first yet hasn’t gone live yet. We’re at the early stage of just having the first cabinets installed.
