Maps and visuals
The route for the electricity transmission line is approximately 732 miles in length, with a typical right-of-way width of 250 feet. Substations/converter stations will be constructed at interconnection points in Wyoming, Utah and Nevada.
Power line design
Along the route, transmission structure heights may vary from 100 feet to 180 feet depending upon structure type, terrain, span and line crossings. The span between structures may vary from 900 to 1,500 feet. The AC structures will look very similar to the DC structures.
