There’s currently a big move underway in Portsmouth (NH). The center lift span of the Memorial Bridge is scheduled to be floated off sometime withing the next 72 hours. The bridge has been closed (structural deficiencies) for months – a new one is on tap with a completion date in 2014. You can watch a web cam here; I’m going to head into town tonight to take some pictures. For folks who don’t know the area, the tide really moves through this section of the river. I imagine they’re going to do the fine positioning of the barge Cape Cod at high tide and let the going tide help float her away.
