The Grand Connection Framework Plan: Sequence Two addresses the Interstate 405 crossing segment of the Grand Connection. The report provides in depth descriptions of each alternative, as well as important information such as planning level cost estimates, travel distance, and amount of open space created. In Fall 2018, the Bellevue City Council directed staff to pursue Alternative Three "Lid Park" for crossing Interstate 405.

Alternative Three - Lid Park
The lid park alternative would seek to create new public space over I-405 between NE 4th and NE 6th Street. Approximately 200,000 square feet of green and plaza space would be created through this alternative, using a rolling landscape to partially cover the access ramps to the interstate and create a unique form. A central plaza would exist for programmable events and public use, surrounded by modest landscaped hills that could be used for play, greenspace, and viewing platforms. A direct elevated connection over 116th Avenue NE would link the Grand Connection to Eastrail multi-use corridor, and an alternative route would connect at grade at 116th Avenue NE through a modest green space.
