APPENDIX A - DESCRIPTION OF TRANSMISSION LINE STRUCTURE
Macro-Corridor Study Appendix A
For most of the Project, the Utilities propose to utilize single-pole structures that would have a typical
height of 150 feet (Figure A-1). The structures would support the new 345 kV high-voltage transmission
line with three current-carrying phases made up of aluminum conductors in addition to two overhead
shield wires for the purpose of lightning protection and protective relay communications. Typical spans
of the transmission line structures would range from 500 to 1,200 feet.
Depending on the final route, the new 345 kV line may be co-located with existing transmission lines.
The typical double-circuited structure is shown in Figure A-2.
Additionally, there may be locations along the route that utilize different structure designs and/or ROW
for purposes of reducing potential impacts. The 345/345-designed structures for the Mississippi River
crossing are proposed as low-profile structures with a design height of approximately 75 feet to reduce the
likelihood of avian collisions. This lower, wider profile would require a 260-foot-wide ROW (Figure A-
3). The structures would be horizontal-symmetrical H-frame structures on concrete foundations with a
typical span length of approximately 500 feet and would consist primarily of tubular steel H-frame
structures. To raise the height of the conductor to cross the Mississippi River, one transition structure in
the Refuge would be required between the low-profile structures in the Refuge and the crossing structure.
This structure would have a proposed height of approximately 90 feet, and the span length would be 500
feet, similar to the remainder of the line in this area. The crossing structures on the banks of the
Mississippi River would also consist primarily of tubular steel H-frame structures and would be
constructed to an approximate height of 196 feet.
The crossing structure height would account for the required distance above the navigable river channel,
as defined by U.S. Coast Guard requirements.
