Engineers managed to push the deck of the Sellwood Bridge about 60 feet north onto new temporary pilings on Saturday.
Friday night, engineers lifted the 1,100-foot deck a couple of inches above its 87-year-old pilings. Then, first thing Saturday they began pushing it north.
Project manager Ian Cannon says the work is done very slowly: "We move it for about 30 seconds, and then we check it, and after each time we've moved it, it's all been in tolerance."
Inch-by-inch, the Sellwood Bridge made its big move over the weekend.
Hundreds of onlookers spent a sunny, but cold, Saturday watching the 87-year-old southeast Portland span move a few yards to aid the construction of its replacement.
"I can't believe how they're moving the whole bridge over," said one young onlooker. "I just can't believe that."
Inch-by-inch, the Sellwood Bridge is on the move.
Hundreds of onlookers spent a sunny, but cold Saturday watching the 87-year-old southeast Portland span move a few yards to aid the construction of its replacement. "It's been quite interesting. I've enjoyed the whole process," said Robert Seidel. "I'm just amazed by the engineering."
The contractor continued to make good progress today to set up the detour bridge. On the second day of the Sellwood Bridge closure progress included:
- Lifting the 10 bearing points of the truss span vertically several inches, in preparation for the big slide tomorrow. The truss span weighs 6.8 million pounds and is almost 1100 feet long.
- Demolition of another concrete span of the east approach
- Installation of deck panels for the east approach tie-in to the detour bridge
The attached photos show some of the dramatic changes that are being made to the 87-year-old structure. The truss span is now completely separated from the east and west approaches, so workers climb a six-story staircase to reach the span.
The project is on schedule for the horizontal slide of the truss span tomorrow, Saturday, January 19. Moving the span is expected to begin around 8:30 a.m. and last all day.
At this time, the project is on schedule for the bridge to reopen by 7 a.m. on Thursday, January 24.
