NCR 23 (Southampton)?

[JtB]

I've already cycled National Cycle Route 23 from Alresford to Reading, this time I want to start off from Southampton. Does anyone know how well NCR 23 is signposted in Southampton from Anderson's Road?

At Basepoint (the store) there is a cycle track that "meanders" onto the Itchen Bridge (NCN 2)

Signposting is not good

this map gives the routes in more detail
