Long’s most visible contribution to the state’s infrastructure was his ambitious program to build roads and bridges, creating the state’s modern highway system. At his death, Louisiana had nearly 16,000 miles of paved and gravel roads and 111 bridges.

In New Orleans, Long constructed a seven-mile seawall around Lake Pontchartrain and built a modern airport, one of the nation’s largest. He also expanded facilities at Charity Hospital and the Port of New Orleans and piped a cheap supply of natural gas into the city and to other population centers.
Long initiated the construction of public hospitals and schools. He tripled the size of Louisiana State University, building new department facilities and a modern football stadium, as well as a new medical school.
To accommodate the growing state government, Long built a new State Capitol building. The Art Deco-style skyscraper was the tallest building in the South. He also built a new Governor’s mansion modeled after the White House. Long asserted that the previous “termite-infested” mansion was not good enough for him, though it had been too good for his predecessors.
