It is a marvel of a bridge! Here is some information I found about it: "Spanning 11 railroad tracks, this bridge connects Amgen’s office complex on the waterfront to a major arterial road. The bridge is designed after the double helix structure of DNA. (Amgen is one of the world’s largest biotech companies.)" [I think I heard Amgen no longer occupies the building there.]
In 2004, the Amgen Helix Pedestrian Bridge received the "Outstanding Project" award under the Bridges and Transportation category given by the National Council of Structural Engineers Association.

It's a very complex structure to sketch. I picked this view as I thought it was a bit challenging but not beyond what I might be able to do. That's Susan H. sitting in front of me.
We were supposed to all begin by meeting at "Fish On" Bait and Tackle Shop/Cafe along the trail. It was hard to find and many didn't make it. I headed back to find a view of the pier. These are the National Oceanographic and Atmospheric Administration (NOAA) ships.
