Existing transmission corridor• 115 kilovolt (kV)
transmission line built in the 1950s
• Easement rights, not ownership on this section of the right-of-way
• Right-of-way is 34 m (110’) wide along Deerpath Drive, with structures located 9 m (30’) east of centre
• Twin pole structures approx. 18-24 m (60’-80’) tall and spaced about 100 m (330’) apart
• Six twin pole structures between the railway and Hanlon Pkwy crossing; the latter is an angle structure
View along Deerpath Drive
Proposed transmission corridor• Upgrade transmission line to
230 kilovolt (kV) on existing corridor under existing easement
• Replace existing structures with steel poles, conventional or narrow base steel lattice towers, approx. 37-40 m (120’-130’) tall
• Spans between poles can be longer; e.g. three poles could replace five existing structures
• New structures adjacent to Deerpath Drive will be closer to the curb
