Sometimes the impact of decisions cannot be ascertained for decades, but planning decisions made in Syracuse are getting a serious review now, nearly sixty years after the stampede to use federal highway funds to clearcut a swath throught the city to make way for Interstate 81.
Of course in the run up to urban renewal and accomodating the automobile age, it made sense to do so and maybe it did and maybe the white flight and neighborhood decay would have happened anyway.
Now, with the highway's useful life expiring there is talk of other ways to accomodate the road, as a tunnel or an on-grade boulevard.
This article in The Atlantic is a good read and a reminder of the impact decisions have both good and bad.
The path of I-81 was surely debated here in the 1960s and the decisions made certainly had impacts not fully understood at the time.
