How 1920s US infrastructure investment could reshape naval competition

What if the United States expanded dams, highways, ports, slips, and dry docks from the 1920s?

The investment could help during the Depression and encourage other governments to copy it, with Britain able to spend on infrastructure despite treaty restrictions on ships.

The proposed dams, highways and enlarged port facilities would leave the United States with infrastructure that could help during the Great Depression. Visible American investment could encourage other governments to follow. Britain provides the naval example: treaty limits constrained warship spending while leaving room to invest in supporting infrastructure. One country's example could make similar public works politically easier elsewhere.
