The project extended over 100 road crossings, eight major highway crossings, four rail line crossings and eight river crossings, including the Tamar River alongside the Batman Bridge. Works were also carried out over the Cataract Gorge, Batman Bridge and through the Trevallyn Nature Reserve.
The project scope included tower strengthening (installation of new steel), assembly and helicopter installation of new earth peaks and stringing new Optical Ground Wire (OPGW). The 85- kilometre line included 243 tower structures and three substations. Most works were conducted under live conditions with only a select few stringing pulls conducted under outage conditions.
