Which U.S. military branch has a direct connection to the establishment of a highway in Alaska during World War 2?

The U.S. Army played a crucial role in the establishment of the Alaska Highway during World War II. This highway, originally constructed as a wartime necessity, was developed to connect the contiguous United States to Alaska. The intent was to enhance the movement of troops and supplies in response to the threat of Japanese invasion. The Army, along with the support of Canadian forces, undertook the massive logistical and engineering challenge of building the highway under challenging weather conditions and difficult terrain.

The highway, known initially as the Alcan Highway, significantly improved transportation access in the region and had lasting impacts on infrastructure and development in Alaska. Its construction represented a significant military engineering effort and reflects the strategic importance of Alaska during the war.

The other branches, while they had roles in the Pacific Theater, particularly the Navy and Marines, did not have the same direct involvement in the construction of the Alaska Highway. The Coast Guard also operated in the region but primarily focused on maritime operations rather than terrestrial infrastructure projects like the highway.
