This addendum Review of Environmental Factors (REF) provides a detailed description of the potential environmental impacts associated with the modification proposed for the Echuca-Moama Bridge Crossing to achieve a more sustainable design and enable substantial cost savings. The proposed modification involves a reduction in the length of bridge structures and a consequent increase in length of the embankment adjoining the bridges. Construction activities of the modification include: * Property acquisition - an additional area of about 1723 square metres (0.17 hectares) of land outside the approved project boundary is required * Removing vegetation * An additional 20,000 cubic metres of material to be used in the adjustments to the abutments. This addendum REF is to be read in conjunction with the Echuca-Moama Bridge Crossing REF, Echuca-Moama Bridge Crossing Submissions Report (29 April 2016), the Victorian Environmental Effects Statement (15 September 2015), and the earlier addendum REF (November 2019).
