Work began in fall 2019 to build the Montlake lid, and the surface of the lid will be in place this summer. As soon as late August, crews will move both Montlake Boulevard and 24th Avenue East onto the lid, giving them space to remove and reconstruct both the Montlake Boulevard and 24th Avenue East overpasses.
During this traffic shift and demolition of the overpasses, you can expect:
- Lane and road closures
- Pedestrian and bike detours
- Noise, dust and vibration from demolition and paving
- New overpasses complete in 2023
To build the lid, crews hoisted heavy girders over the highway lanes to create the framework. Crews are pouring a series of five concrete sections to make up the surface of the lid. These activities began in early April and will wrap up in July.
