Watching the Ravenel Bridge Grow
T.S. Eliot (East Coker from the Four Quartets) put it this way:
Old men ought to be explorersHere and there does not matter
We must be still and still movingInto another intensity
For a further union, a deeper communion

How this happened
My wife and I have a small kitchen house on Ashley Avenue. From time to time some of our grandchildren
would come for a visit. Frequently we took them to the South Carolina Aquarium – a great place for grandkids and grandparents. During August and October 2003 I took photos of the kids standing on the outside terrace. Later I noticed that the Ravenel Bridge was growing. This started a weekend trip to the pier adjacent to the
IMAX theater. I built a web page to share the photos: http://ravenelbridge.net. The web page opened many
doors. Here is the story of what I saw.

Fog Surrounds the Main Span
My first visit to the main span. I was struck by the number of
independent processes: building a cable, placing concrete road sections, balancing the bridge.

Sunday morning (7am) bicycle rides across the

construction. This morning, the Mt. Pleasant Police were running interference for me

The Charleston Approach Skeleton
The symmetry of the structural steel drew my
attention to small details – was anything out of place?

A Cable Strand
A stay cable is built one strand at a time. The cable is fed up
the stay cable pipe and terminated in the tower and bridge platform. Here the Freyssinet workers feed a
strand down to the termination plate.

Freyssinet: Building the Last Cable
I was fascinated with the process of building a stay
cable. Composed of many strands, pairs of cables were fed from spools up
the stay pipe. Each strand was terminated at a shark fin anchor and within the
diamond towers
