Answered By: 
The Mayor

Calcium Magnesium Acetate (CMA or dust suppressant) is applied daily. CMA is applied between 21:00 and 06:00 when London's roads are quietest. The actual time that the south London vehicle operates along Blackwall tunnel varies depending on operational considerations, but the Blackwall tunnel is generally the third corridor to be treated between 00:00 and 02:00.
