Sellwood Bridge Update- A Peek At What’s Coming Up

aaaBridgeUpdateButtonRestOfNewsletterThe third bridge closure went according to the pattern set so far… the inconvenient closure happens, the work goes smoothly, and the bridge opens ahead of schedule.  It’s a slightly unexpected, but very nice pattern to have for a gigantic, complex construction project!  To relive the golden moments of the support installation we bring you these photos of our own, and we’d also like to direct you to David Ashton’s excellent article on the episode for the Sellwood Bee, the local paper that’s been following the Bridge reconstruction from the very first public meetings.
