Question to the Department for Transport:

To ask the Secretary of State for Transport, (a) how many movements and (b) what proportion of barge traffic on the tidal Thames between Richmond and Tower Bridges was connected to the (i) Northern Line extension at Battersea and (ii) Thames Tideway Tunnel in each of the last 12 months; and what the projected changes in those numbers and percentages are after completion of those projects.

The Port of London Authority (PLA) is the navigation authority for the tidal Thames. The Department for Transport therefore does not hold data on vessel movements on the Thames or intermodal connections.
