Vic third runway to impact on 3000 homes MELBOURNE Airport's proposed third runway will put more than 3000 homes in Tullamarine, Gladstone Park and Broadmeadows under the new flight path. The Herald Sun says the new runway will sit parallel to the existing east-west runway and begin operating between 2018 and 2022 to cope with growing numbers of passengers coming to Victoria. The airport's owners have revealed the third runway will be used mostly for arrivals with planes coming in over Broadmeadows and descending over Gladstone Park before landing.
