released The end result is compressed and stronger concrete 07/17 Crossing Lake Washington EAST LINK EXTENSION Pioneering engineering As part of the East Link extension, Sound Transit will do something that’s never been done before—run light rail trains across a oating ridge To do this, engineers and designers had to consider a number of factors, including six ranges of motion as trains trael onto the oating portion of the ridge eres ho e stepped up to the challenge What did we do? To accommodate running trains from the land ridge to the oating ridge, Sound Transit built two life-size test trac ridges The trac ridges consist of rails that rest on a series of bearings and plates to let them move with the changing lake levels and ridge moements Passing the test Sound Transit shipped the test bridges and two light rail vehicles to the Transportation Technology Center (TTC) in Pueblo, Colorado, where freight and commuter rail agencies from around the country test ne technologies At the TTC, Sound Transit was able to mimic the forces and movements the track bridges will experience during normal and extreme conditions, including lake level, sway, roll and surge forces The results After collecting more than 500 channels of data during each light rail vehicle pass, the track bridges passed all critical test criteria with the ability to provide safe and comfortale light rail serice at speeds up to mph Learn more about the track bridge and watch a video soundtransit.org/trackbridge 07/17 JUDKINS PARK CONSTRUCTION TIMELINE EAST LINK EXTENSION MARTIN LUTHER KING JR WAY S WAY JR KING LUTHER MARTIN 1 1 23RD AVE S AVE 23RD 2TH AVE E AVE 2TH E AVE 4TH 5 405 112TH AVE SE 112TH E YESLER WAY E YESLER WY 31ST AVE S AVE 31ST 118TH AVE SE AVE 118TH 108TH AVE SE AVE 108TH 104TH AVE SE 104TH BLOCK 2 98TH AVE SE S JACKSON ST S JACKSON ST S JACKSON ST Lake Washington LAKESIDE AVE S 1 2TH AVE S AVE 2TH D2 Roadway SE AVE 123RD MARTIN LUTHER KING JR WAY S WAY JR KING LUTHER MARTIN BELLEVUE WAY SE Seattle S LAKESIDE AVE 23RD AVE S AVE 23RD RAINIER AVE S 31ST AVE S AVE 31ST 405 405 118TH AVE SE AVE 118TH GOLF DR S BLOCK 6 N MERCER WAY 112TH AVE SE 72ND AVE SE AVE 72ND Bellevue SE 20TH PL AIRPORT WAY S 15TH AVE S Mt.
