- November - The Ambassador Bridge opens between Detroit, Michigan and Windsor, Ontario, commemorating the Americans and Canadians who served together in World War I.
- Detroit Fusion is formed after the merger of several local power companies. DTF is tasked with supplying electricity to the entire metro Detroit area and much of southern Michigan.
- The Michigan Super Highway opens to the public, the culmination of three years of Chryslus Motors lobbying the Great Midwest Commonwealth government. The highway has no speed limits and quickly boosts tourism, and fatal accidents, across the state.
- The Chryslus Motors Megaplex began when Chryslus connected their corporate headquarters and main R&D center with two adjacent factories. More additions came in the following years as neighboring rivals went out of business and Chryslus purchased their land.
- Nuka Cola begins making attempts to acquire Chuggo Soda. The attempts includes several lawsuits.
- August - The annual "Assembly of the Chuggalos" is held in the Nuka World parking lot. Afterward, Nuka Cola abandons its attempts to acquire Chuggo Soda.
- Boblo Island is "gifted" to the U.S. by Canada to help with the war effort, one of the first land secessions not in the proximity of Trans-Alaskan Pipeline.. Timber resources on the island are wiped out and it is used as a dumping ground for Detroit factories afterward.
- October - Jed Abrams wins the 2072 Belle Isle Grand Prix after causing a crash that left two dead. Jed's win was scratched after he underwent drug-screening and tested positive for Buffout, X-Cell, and Psycho.
- January - The United States annexation of Canada is complete. Canadian protesters and rioters are shot on sight, and the Alaskan Pipeline swarms with American military units. Pictures of atrocities make their way to the United States, causing further unrest and protests.

- The Vault Dweller, along with the Brotherhood of Steel, defeats the Master and his Super Mutant army. Afterward, the debate about outside recruitment is reopened. At some point between 2162 and 2198, the Brotherhood constructed great airships and sent those in favor of outside recruitment east, to assess the threat of the remnants of the Master's Army. The airships were knocked off course and crash-landed near Chicago. The survivors of the crash became known as the Midwestern Brotherhood of Steel.
- The Hunters arrive in Royal Oak. They and the locals of the Motor City Wasteland keep their distance from each other. The raiders think them to be wild; the Hunters think the same of the raiders.
