I'm curious what you think this toucan crossing connects to, once you've crossed Lower Lea Crossing going north on a bike:

It either connects to the pavement (possible) or more likely to the riverside walk, which you've now tagged as requiring a dismount. That doesn't make sense.

My references to Silvocea Way come from the little number plates on each of the lamp posts along the riverside railing by the way (though the council misspelled it IIRC, oops):
