* This flythrough is a visualisation created to support the consultation for the Eastern Green Link 3 and Eastern Green Link 4 projects. The flythrough has been built using real world data, to portray the existing landscape. Please note, however, that some recent changes to the terrain, vegetation or structures may not have been captured. The datasets used may also change over time and this may affect the accuracy of the visualisation. The flythrough is intended to be illustrative of our proposals and should be viewed in conjunction with other published consultation materials.
