The Safeco Bridge, also known as the Alaskan Way Viaduct, was once a vital elevated roadway in Seattle, running along the waterfront and connecting downtown to southern neighborhoods and the Port of Seattle. Built in the 1950s, it was part of Seattleβs post-war growth. However, after the 2001 earthquake brought about safety concerns, the viaduct was replaced by the State Route 99 Tunnel in 2019. Today the area has been redeveloped into a vibrant public space with parks and great views.

Thank goodness for Seattle's many, many pocket parks such as this one. They allow public access to the lakefront and often are quirky, wonderful little out-of-the-way spaces all on their own. Stop here for a rest and some wading in the shallows!

Right off the Burke Gilman Trail - a bit of a steep hill to the beach, but worth it. Good swimming beach in the summer.
