Admiral Ackbar's points are valid, but even that is something of a challenge, but I think its possible.
My Transport America TL (shameless plug
) is one option. Long and short there is that in the aftermath of WWII, social and cultural changes happen in America. In most of the union, World War II and the huge number of black servicemen who fought with honor massively reduces the problems with racism in America, and many GIs enter the police forces of numerous major cities, which reduces racial tensions, and also leads to gradual reductions in restrictions on where black people could live in US cities. President Eisenhower, well aware of both the autobahns and America's railroads carrying so much in WWII, builds the Interstate Highway System but at the same time enacts numerous programs to rail transit in America of all forms, from small intermodals to massive freight railroads, resulting in much-increased mass transit, which both slows the growth of suburbs somewhat and also improves America's economic state. In the 1960s, the white flight still happens but many newer arrivals to neighborhoods stay put and clean up communities, resulting in nearly all major American cities staying much better on the inside. The 1970s is not nearly as bad of an economic malaise as IOTL, and the late 1970s and throughout the 1980s sees a major movement to integrate the needs of business and labor, resulting in massive improvements to the United States' industrial infrastructure and yet huge growth in unionism, and it also results in massive wage growth for the poorer and middle classes in American society in the 1980s and 1990s. Combined with the reduction of crime in major cities of IOTL and much better mass transit, American cities see a huge renaissance in the 1990s and 2000s.
New York in that world has a good transit infrastructure before Robert Moses, and while Moses is still able to advance the automobile, he does not do the damage to New York's transit that he did IOTL. In addition to that, this world does not see New York's middle-class hollowed out as much as IOTL, which means that the city is not effectively bankrupt by the middle of the 1970s. Thus, New York is one of the first places to see a massive revival in the 1980s, a revival that keeps going right up to now. In addition to that, the much less hollowing out of manufacturing industries means that things are much better in places like Buffalo, Niagara Falls, Rochester, Syracuse and Albany. In the city of New York, the chaos of the John Lindsay and Abe Beame years is much less than OTL, and the local authorities are also part of the much less confrontational style between public sector unions and the government in the 1980s and 1990s. How much that helps, I'm not exactly sure, but I can't see it being a hinderance.
