The Montlake Lid shows the basics of how we will lid the Interstate 5 lanes between Downtown and First Hill & Capitol Hill – it’s not much more than thick walls and hefty girders. The lid will hold a new neighborhood park, and also a regional bus stop. Further to the east, a swooping land bridge will improve walking and cycling connections.

The Montlake Lid is part of a larger rebuild of State Route 520. Previous phases included three lids east of Lake Washington and a new floating bridge. The Montlake portion of the project is expected to be completed in 2024. The final phase, connecting to Interstate 5, is planned to be built 2023-2029 and will include an additional lid in the Roanoke neighborhood. See the WSDOT project website for details.
