On Tuesday, March 11, 2025, the Bellevue City Council unanimously approved a new budget and plan for the Grand Connection Crossing over Interstate 405. This pedestrian and bike bridge, set to open by 2030, will be a key part of the Grand Connection, a car-free pathway running from Meydenbauer Bay to the Eastrail trail in Wilburton.
The design includes wide pathways, landscaping, and separate lanes for walking, biking, and rolling. The estimated cost is between $150 million and $200 million.
The Grand Connection Crossing will provide a safer way to cross I-405, improve access to local trails and transit, and help create public spaces. Earlier this year, the city shared a 30% design plan based on community feedback and engineering needs. This plan serves as a long-term vision, with elements that can be built in phases or alongside future development projects.
The design presented to the council focuses on the most important features while remaining practical for early construction. Over the next few months, the city will refine the design, complete engineering plans, and finalize a funding strategy.
The Grand Connection project aims to create a 1.5-mile pedestrian-friendly corridor connecting downtown Bellevue to Eastrail. The new crossing is a key part of this, making it easier and safer to get around without a car.
Key features include:
- A bridge at least 30 feet wide, expanding to 40 feet over I-405
- Separate paths for walking and biking
- Landscaping along the entire span
- Gathering spaces at both ends, with potential for more public areas in future development
- A mid-bridge elevator and stairway for access
The city’s project team has recommended a budget of $150 million to $200 million for final design, land acquisition, and construction. This budget allows for a safe and functional crossing by 2030, with the possibility of adding more features later.
Funding comes from both public and private sources. Amazon contributed $2.5 million for early design work, and Bellevue’s Capital Investment Program (CIP) provided another $3.6 million. The city council has allocated $15 million in the 2025-26 budget to continue design efforts. Additional funding will be needed to complete the project.
In 2025, the city will refine the design and finalize funding plans. The crossing is expected to handle around 10,000 users each weekday by 2044, supporting Bellevue’s growth and commitment to safe, sustainable transportation.
