It was quite a sight yesterday as the new Willis Avenue Bridge floated up the East River. I found some great video of the last leg of its voyage on the NY POST website.
The bridge was built upstate, floated down the Hudson over the last couple weeks and finally arrived in Harlem yesterday where it will replace a span that is more than 100 years old. The original span cost about 2M and then new one....614M. It's the most expensive bridge the Department of Transportation has ever built.
It's been a long time coming as the current bridge has been falling apart for years. Installation begins in August and traffic should be flowing in November.
