Bridge to Nowhere

I’ve been thinking about doing a photo 365 project for a while.  It’s been over a week since I shot anything, but it’s been dark at night and I’ve been busy.  c’est la vie.  We’ll see when I actually launch the project.  A friend of mine is already on his second 365.

I got out today with my D90, 18-200 VRI and my cheesy Circular Polarizer (Qantary) to take photos of the General Sullvan Bridge between Dover and Newington, NH. They are moving the ramp to make room to expand the Little Bay Bridge, which is built right next to it and takes all the vehicle traffic. The good news, according to the Fosters, is they are going to keep the General Sullivan bridge for pedestrian traffic.

If you take a look at larger versions of the photos and a full sideshow, you might notice a few are slightly less sharp (even less sharp than a 18-200 is usually).  I forgot to turn back on my VR and didn’t notice until I was done.  Shame on me.  I have to put a mental checklist together to remember to turn ISO back to auto, shooting mode to “P” (when I’m intending to use it) and VR and auto-focus back on.

I find construction sites very fascinating in that there is always something to learn just by looking around.  It’s like a live living museum and over time when you look back you see the technology change.

For example I had never seen pilings before with a pointed end.  It makes sense especially if the plan is to fill them with cement.  To me they look a little bit like missiles.  I’m not sure what I thought about bridge pilings before and what would be at the tip of them.

Also of interest is how during winter months we go about curing Cement in New Hampshire.  I knew they made antifreeze mixes that they added to the cement to allow it to cure in cold weather, but I now see that it has limitations.  I’m guessing because of the higher strength required for a bridge, that they need to cure it differently.  This is a “Mobile Glycol Heating System” – implying to me that its the inverse of the cooling pipes the used on the hoover dam.  They are heating glycol and using hoses to keep keep the cement warm.
