Thanks for adding this, but please note that maxweight=* restrictions (restricting the actual weight of the vehicle) are now quite rare on public highways in the UK, with only a few pre-1994 legacy road signs remaining.

For weak bridge/weak road weight restrictions, tag as maxweightrating=*

For HGV weight restrictions, as in this case, tag as maxweightrating:hgv=*
"except for access" maxweightrating:hgv:conditional=none @ destination
"except for loading" maxweightrating:hgv:conditional=none @ delivery
