When you stand near the lakeside homes in Medina, Yarrow Point, Clyde Hill or Hunts Point, it鈥檚 hard to imagine that neighbors have anything to complain about, but some residents are highly irritated with a 鈥渢hunk鈥 that鈥檚 been haunting the area.

The thunk sound has been connected to the new 520 floating bridge. The bridge has been open for about two months, but the honeymoon is definitely over for people living on the Eastside.
Since April, more than 200 people have filed noise complaints over the sound of cars rolling over the new 520 bridge expansion joints. It鈥檚 a ka-thunk, zzzzz, thunk-thunk noise, depending on who you ask.
Some Eastside communities claim the 520 bridge noise is unbearable and they want the state to fix it. The Washington State Department of Transportation says they’ve done everything by the book, but will continue to study the noise.
鈥淭here鈥檚 people who literally didn鈥檛 hear the old 520 at all,” said聽Medina City Manager Michael Sauerwein. “Now they can stand in their living room and can hear the ‘ka-thunk-ka-thunk’ noise. They feel like they can鈥檛 even open the windows in their bedrooms without it keeping them awake at night.鈥
Julie Meredith, the administrator of the 520 Bridge Project, adds that there is more construction work to be done, but so far the new 520 bridge has met the sound requirements for noise reduction.
鈥淭he combination of enclosing the expansion joints below, noise walls and new pavement, has decreased the noise from what we had before (the old 520 bridge) and helped us meet the federal noise abatement criteria,鈥 Meredith said.
This really seems like round one of an ongoing debate, but Medina residents don鈥檛 seem to be backing down.
鈥淥ur citizens will be contacting their representatives at the state level to encourage Washington State Department of Transportation to help us find a solution to the problem,鈥 Sauerwein said.
What if the thunk noise simply turns out to be the new normal for Eastside residents?
鈥淭his is not just an annoyance, this is significantly impacting the quality of life of a number of citizens that live in this area,鈥 Sauerwein said.
At this point, the new 520 bridge is almost finished. So what鈥檚 next? Will the city of Medina eventually sue the state over the noise? Emails to Sauerwein鈥檚 office about a potential lawsuit went unanswered.
