The East Link light rail project aims to improve public transit between downtown Seattle and the Eastside, with planned stations in Mercer Island, Bellevue, and Redmond. Initially set to open in late 2023, the timeline has shifted to spring 2025 due to various construction challenges. This expansion is crucial for meeting the increasing transportation demands driven by rapid economic and population growth in the Eastside region. East Link will provide quick, reliable travel options, with ride times from Mercer Island to the International District taking just 10 minutes, and to Sea-Tac Airport approximately 46 minutes with a transfer. The integration with the existing Central Link line will facilitate easy travel without the need for transfers, enhancing convenience for commuters.

Community involvement has been a vital aspect of the project, with public meetings and input opportunities held throughout its planning and implementation phases. Environmental assessments have ensured that local impacts are considered, and mitigation measures have been implemented. Overall, East Link is set to be a transformative addition to the Puget Sound region's public transportation landscape.
