Fremont Bridge, Winter, Dusk

Fremont Bridge: Finished in 1973, this is Portland's newest bridge over the Willamette. The double-decked Fremont Bridge connects northbound I-405 and westbound US-30 to I-5. It weighs 6,000 tons and was lifted 170 feet - a Guinness Book of World Records entry for heaviest lift ever made at the time.  The tied arch span is 902 feet long and was not built on-site but floated on the river into place.
