Blumenauer Bridge installation Oct. 8-11
Interstate 84 east of Interstate 5 was closed in both directions Oct. 8 to 11, while crews installed the new Congressman Earl Blumenauer Pedestrian and Bicycle Bridge.
The installation was delayed in July when it was determined that the railroad would not be clear for the cranes to operate in the same space.
The Portland Bureau of Transportation issued the following warning for this weekend's traffic:
Both eastbound and westbound I-84, along with on-ramps, will be closed, with some variations, around the clock from 10 p.m. Friday, Oct. 8 to 5 a.m. Monday, Oct. 11.
The bridge has to cross eight freeway lanes, but other constraints were not evident to the passer-by. Oregon Department of Transportation rules said it has to stay at least 17.5 feet above the roadway (it will be 40 feet), and the railroad company Union Pacific says it must be at least 23 feet over the tracks. ODOT didn't want any bridge support built on the south embankment in case they ever wanted to widen the freeway. PBOT owns the north embankment and said it was OK to build support there.
"The span lands quickly, in as short a distance as possible after it's cleared the Union Pacific tracks," structural engineer Craig Totten told the Tribune in May. "So that's why the intermediate support drops down on the floor."
When complete, the Blumenauer Bridge will connect pedestrians and bikers on Northeast Seventh Avenue between two of Portland's fastest-growing neighborhoods — Lloyd and the Central Eastside — and beyond. In the future, it also will serve as an essential link for Portland's Green Loop.
The bridge is tentatively scheduled to open to the public in mid 2022.
