Question to the Department for Transport:

To ask the Secretary of State for Transport, pursuant to the Answer of 11 July 2025 to Question 65933 on Dartford-Thurrock Crossing: Tolls, what estimate she has made of the change in the level of car journeys on that crossing due to (a) the change in charges and (b) other factors for the years 2025 to 2030 inclusive.

Our assessment is that average daily car journeys at the Dartford Crossing during the chargeable hours (0600-2200) for the first twelve months after the increase in charges will be between 4500-6000 fewer than would otherwise have been the case. We consider those figures should be treated with caution given the limitations of the assessment however, and consequently that it is the expected trends for changed traffic demand given in the answer of 11 July that are the more pertinent consideration. No estimates have been made for the other years or other factors.
