VIEW MERCER ISLAND CAMERAS →Mercer Island, Washington, is a premier residential and transit anchor positioned at the strategic heart of the Seattle metropolitan area. Positioned entirely within Lake Washington and serving as the primary transit link between Seattle and Bellevue, Mercer Island handles an immense daily volume of regional commuters. With Interstate 90 serving as the island's sole high-capacity connection to the mainland, managing the flow of traffic across its floating bridges and arterial streets is essential for maintaining the region's mobility and resident quality of life.
TrafficVision aggregates feeds from the Washington State Department of Transportation (WSDOT) and local municipal sources, providing a comprehensive view of the Washington camera network. Whether you're navigating the morning rush toward SeaTac or heading to a shop at the Town Center, our live street cameras help you bypass the most notorious bottlenecks in real-time.

Strategic Mobility in the Heart of the Sound
The traffic landscape in Mercer Island is a coordinated effort between WSDOT and the City of Mercer Island. The region handles some of the highest daily volumes in the Pacific Northwest; the I-90 floating bridge segment alone handles an average of over 157,000 vehicles daily, including a high percentage of regional bus and transit traffic.
While Mercer Island residents enjoy a relatively efficient average commute of just 25 minutes, the complexity of the bridge approaches can cause sudden delays of 20 minutes or more. Real-time monitoring is a vital daily tool for residents. Research from the Federal Highway Administration (FHWA) suggests that live traffic camera feeds can reduce secondary accident rates by up to 30%. By spotting a backup at the West Mercer Way exit early, you can use our route builder to find a faster alternative through local A-roads or the future Link light rail corridor.

OPEN INTERACTIVE MAP →Key Commute Patterns and Bridge Impact
Traffic in Mercer Island is heavily dictated by the "outbound morning, inbound evening" pattern common to residential anchors. Peak morning hours (6:00 AM – 9:00 AM) see extreme volume heading toward both Seattle and Bellevue employment centers, while the evening rush (3:30 PM – 6:30 PM) brings that volume back toward the residential districts of the island.
The I-90 Floating Bridge, comprised of the Hadley and Murrow spans, remains one of the most monitored chokepoints in the country. Our grid view allows you to monitor these multiple bridge levels side-by-side, helping you decide if taking the East Channel alternative is your best option today. This is especially vital during the Sound's frequent winter windstorms and rain events, which can suddenly impact visibility and road traction on the high-speed freeway spans.
Pro Tip: 2 Line Light Rail Strategy
The Mercer Island Station on Sound Transit's 2 Line is scheduled to open in March 2026. Check our cameras at the 77th and 80th Avenue entrances before you leave; as more commuters shift to light rail, these surface approaches will become critical barometers for the overall island transit flow.
