Square Challenge — Time

Becky has a new Square format photo challenge for the month of December and the theme is Time.

The Golden Gate Bridge has eight independently moving scaffolds underneath the roadway so that maintenance crews can access portions of the bridge that need to be repaired/repainted. Four inner scaffolds can run the entire length of the bridge and four outer scaffolds—two on each side of the center of the bridge—operate between a tower and midspan.

Each scaffold has a diesel powered generator and a control box chock full of motor controls and many Time Delay relays, which insure everything doesn’t happen at once when the start button is pushed and levers are engaged.

These scaffolds and electrical controls were installed in the early 1950s and require a lot of maintenance to keep the scaffolds running and the crews working. The scaffolds and controllers will be replaced as part of the Suicide Barrier Project currently underway.

Based on my experience with the scaffold controllers, the replacements will be just in the nick of Time.

    It is mind boggling to think of all of this being planned and installed in the first place, and all this going on behind the scenes of all of us crossing the bridge. Amazing! And, yes, looks like time for a little refreshing.

      Thanks for your comment, Angeline. It is exciting for me to see the changes taking place on the GGB these days. I feel like I am part of a “bridging generation” of workers who went thru the transition of one millennium to the next with a structure that is timeless.
