Hyde Park is definitely a bigger version of Avondale. As someone who lived in Jacksonville prior to my 4 years here in Tampa, I would say that the biggest difference between the two areas is that Hyde Park is the desirable area for both the established rich people and young professionals. When I lived in Jacksonville, I don't remember too many of the young professionals trying to live in Avondale. Tampa also seems to have more people who are interested in revitalizing downtown and historic neighborhoods, although we are still woefully behind. Hyde Park could be a lot better and I would look to Winter Park as the example of the way to do things.
The freeway infrastructure in the entire metro area is piss poor. We are really paying for all of the freeway revolts in the 1970's. Freeways are not the answer to all transportation needs, but every metro area needs a certain amount of them to make the area easy to get around. The article says that the Selmon Exwy cut off much of the neighborhood from UT and Soho. That isn't entirely accurate. The CSX railroad tracks already separated most of the neighborhood from Soho. When the expressway was built, the railroad right of way was used. The expressway did not cut off any through streets south of Platt, as those were already cut off by the railroad. Only a small portion near UT was cut off. Even then, it is still very easy for pedestrians to cross under the expressway, unlike many urban expressways that were built and unlike I-275, which plowed through several historical neighborhoods.
