Urban redevelopment has been a mainstay of many cities across the USA with significant success. San Antonio is a prime example of how to do it right. RiverWalk in Milwaukee misses the mark that is set so high by other cities.
The river and its surrounding building are not that nice to begin with. There is a lack of restaurants and shops along the route. The walkways do not "connect;" you have to cross busy streets to continue along the route. Nice idea, but it just doesn't work in Milwaukee
