The building work had started before the go-ahead was officially given !!. The sewage works had already started to be demolished and a new taxiway had been built a few years ago, it is currently used as parking stands at the moment - known as the 160 stands. The tunnel between the central area and the T5
site is also nearing completion having been started about 2 years ago.
These pictures below show the construction work. If you compare the size of the T5
site in the left picture with the size of the existing central area you can see it's about the same size !!
Also just for your info, if you look at the left of the left hand picture, where runway 23 is and those taxiways - the plan is to extened the T1 Europier out to where runway 23 is located and to build to parallel taxiways between 27L/R that run straight between the 2 runways rather than all wonkey as they are at the moment - this will be done once the 3rd runway is given the go-ahead.
