A second explosive demolition will be carried out at the last remaining power station on the River Thames tonight (Saturday).

At 11pm a turbine hall at Littlebrook Power Station, next to the Dartford Crossing, will be brought down.

The structure consists of a structural steel frame with a concrete skin and steel cladding.

The timing of the event will coincide with the already planned closure of the QE2 Bridge for maintenance, so as not to distract drivers.

The 10-second event will not be visible from outside the station boundary and the site will be off limits during the demolition.

Although the explosion and collapse may be heard off site, any noise will be over very quickly and non-harmful dust is extremely unlikely to go beyond the station’s grounds.

The other main structures will be blown up throughout the year and into 2019, with the site fully cleared by 2020.
