Patrick writes: "This next batch is primarily of that from ground level and the anchorages."
From a Mott MacDonald article about the bridge: "Safety is ensured in part by the foundations designed by Mott MacDonald. Cables at each end of the bridge are anchored to the ground using concrete abutments, each one about 80 feet wide, 16 feet long, and 15 feet deep. The abutments are fastened to the underlying sandstone using post-tensioned rock anchors up to 135 feet long." Those dimensions makes for over 700 cubic yards of concrete in each anchorage.
Patrick continues: "In the first photo and then again [several photos down] you can see boxy bump outs from the face of the anchorage where the ends of the post-tensioned rock anchors are located."
"[In the next four photos] you can see boxy bump outs from the face of the anchorage where the ends of the post-tensioned rock anchors are located."
Patrick writes: "This batch is of the undersides of the walkways atop the main cables and of what appears as tuned mass dampers on the underside of the main deck. Another deck movement mitigation method appears to be the significant spine made up of a steal box beam and then timber, running the main deck's underside within the mainspan."
