The smart way to reduce congestion (not that this expansion has it, 5%
of the area at most has congestion) is to close off zones and reduce
flow. Classic example Hammersmith bridge. Close it and traffic
"evaporates".

Traffic might have evaporated from Castlenau/Lonsdale Road and the
surrounding roads to the south of the bridge. But, it miraculously
condensed on neighbouring bridges, with Putney seeing most of the
increases, although Chiswick and Kew were affected.

While it was a great boost to the quality of life to many in the area to
the south of the Bridge, closing Hammersmith Bridge was not a
"victimless crime".

Tolling the bridges, though - that's not an idea much mentioned. Given
the voracious traffic wardens in Wandsworth, especially, tolling the
bridges would bring in a whole wedge of new revenue.
