Painted Bridges - Alkaff Bridge (3)

One last photo of the Alkaff Bridge. I really like tubular members for steel bridges. They have good performance well beyond the elastic range and they're more attractive than the I girders and other members usually chosen for steel bridges.

If you look closely, you can see steel caps at the ends of the members. The caps look like they have vents on the end, but that must be an artistic embellishment by the artist (Pacita Abad). I like her signature near the end of the bottom chord. We should all get to sign our bridges with such panache!

On the far side of the river are bridge workers (perhaps the PIRAS rope climbing crew) touching up Pacita's handiwork. They're wearing harnesses and hanging from static lines in a similar fashion to bridge inspectors in California.
