Heathrow’s airport expansion had gotten the green light from the government after years of delays. British lawmakers voted in favor of the third runway construction that could start in 2021. For years, the proposal had gone through a lot of strong opposition considering factors that would be forsaken in the said expansion. Air traffic, level of noise in nearby cities, and air pollution crisis are things that the opposing team looked into over the debates.

Under the proposal, at least 750 homes in the villages of Longford, Sipson, and Harmondsworth will be demolished. By 2030, Heathrow expects the number of passengers to jump from nearly 80 million per year to 110 million. The third runway will be built parallel to the two existing strips. Transport secretary Chris Grayling said that the construction would be a big leap to London’s economic growth since the new runway will allow more connecting flights to other UK airports.
