SEATTLE — Thousands of people turned out Saturday for festivities celebrating the opening of the new state Highway 520 floating bridge across Lake Washington — so many that the state Department of Transportation declared the event “at capacity” and halted buses that had been expected to shuttle additional people to the structure.
Gov. Jay Inslee cut an orange ribbon Saturday at the middle of the 1.5-mile-long span to commemorate the completion of work, more than 12,000 people participated in a 10K fun run, and a representative of Guinness World Records presented a certificate designating it the world’s longest floating bridge — at 7,708 feet, it’s about 130 feet longer than the old one.
“This is what it’s all about – seeing years of public engagement, planning, design and construction all come to fruition,” said Roger Millar, acting transportation secretary. “This grand bridge is going to serve our region well for a long, long time.”
The six-lane bridge, which replaces a four-lane version built in 1963, doesn’t fully open to car traffic until later this month — April 11 for westbound traffic and April 25 for both directions. The state says it features heavier, stronger pontoons and anchors that allow the structure to withstand stronger winds and waves; a bus and carpool lane in each direction; a 14-foot-wide bike and pedestrian path; and system to collect and treat storm water, which will improve water quality in Lake Washington.
