The Washington Department of Transportation (WSDOT) and the City of Seattle are hosting an open house this Thursday, September 11, and I encourage folks to stop by. There will be displays showing the design enhancements for the Seattle portion of the 520 expansion—including the refined lid concept for the Montlake neighborhood.
The previous lid design had many strengths but also some real shortcomings.
Because of its length, the lid would require mechanical ventilation including massive, 20 foot high ventilation shafts, and a permanent maintenance facility and parking lot.
The old design resulted in steep, indirect and disconnected pedestrian and cycle connections—and public open spaces that invited misuse. Furthermore, the lid’s boxy shape projected awkwardly into the Lake Washington shoreline, marring the natural landscape.
In a case of less-is-more the new shorter lid eliminates the need for the stacks and maintenance facility, improves pedestrian and cycle connections while providing comparable levels of screening and noise reduction.
But don’t take my word for it. Come to the open house on September 11, 4:30-7, at the Montlake Community Center, bring an open mind and judge for yourself.
Montlake Community Center, September 11, 2014, 4:30 to 7:00 p.m.
