24 Proceedings Fall 2025 sectors are especially pronounced in Alaska due to the state’s isolation. Communications towers must withstand extreme temperatures and wind speeds. Water treat- ment facilities often rely on specialized supply chains for chemicals and parts. Energy infrastructure, from electricity generation to fuel transport, can be disrupted by harsh weather and seasonal conditions. Perhaps most importantly, transportation systems in Alaska frequently intersect with energy routes—fuel barges need secure ports, trucks need well-maintained roads, and ferries require reliable dock facilities. When one lifeline stum- bles, the effect is felt across the others, intensifying the need for holistic infrastructure planning and investment. The Alaska Factor Alaska’s distribution system is best described as a net- work of single transit routes extending longitudinally throughout the state, with minimal cross-connectivity. The state’s reliance on maritime transport, including cargo ships, barges, and ferries, further compounds logistical challenges, making supply chain disruptions a looming risk. Additionally, many inland communities depend on barge traffic to receive essential goods, making real-time supply chain management an indispensable tool. Alaska’s remote environment necessitates a heavy critical port operations remains front and center. The U.S. government categorizes critical infrastruc- ture (CI) into 16 sectors as outlined in the 2013 National Infrastructure Protection Plan (NIPP).1 The Department of Homeland Security designates sector-specific agencies to oversee 10 of these sectors, with the Coast Guard and the Transportation Security Administration responsible for the transportation systems sector. Given its vital role, the Coast Guard must ensure that ports remain func- tional, facilitating the shipment of goods essential to both Alaska and the broader national economy. Within the 16 CI sectors, four have been identified as lifeline sectors by the Cybersecurity and Infrastructure Security Agency (CISA) due to their critical interdepen- dencies. CISA states that they are “critical to the opera- tions of almost all other sectors, as well as each other, and are fundamental to the delivery of the basic societal functions communities seek to provide.”2 These sec- tors—communications, water, energy, and transporta- tion systems—are fundamental to maintaining societal functions. Transportation in particular serves as the backbone that connects these lifelines, underscoring its significance in ensuring national security and economic stability. Beyond their official designations, these four lifeline Transportation is one of four infrastructure sectors critical to the operations of almost all other sectors, as well as each other. The other three are energy, communications, and water. Together, they are fundamental to the delivery of the basic societal functions communities seek to provide.
