The Evergreen Point Floating Bridge

The Evergreen Point Floating Bridge, also known as the Governor Albert D. Rosellini Bridge, stretches 8,549 feet across Lake Washington, connecting Seattle to the town of Medina. Built in 1963, the bridge is the longest floating bridge in the world and the longest of its type in the United States. It is also the widest bridge in the world, with a total width of 116 feet. The bridge is supported by 78 pontoons, which are anchored to the lake bed with steel cables.

The bridge is a major part of the Seattle area’s transportation infrastructure, carrying over 100,000 vehicles per day. It is a vital link between Seattle and its eastern suburbs, providing access to jobs, schools, shopping, and recreation. The bridge is also a popular tourist destination, offering stunning views of Lake Washington and the Seattle skyline.

The Design and Construction of the Bridge

The Evergreen Point Floating Bridge was designed by the engineering firm of Sverdrup & Parcel and Associates. The bridge was designed to be able to withstand the strong winds and waves of the Puget Sound, as well as seismic activity. The bridge was built in three sections, with the pontoons being constructed in a dry dock on the shore of Lake Washington. The sections were then floated into place and connected.

The bridge was built using a combination of steel and concrete. The deck of the bridge is made of steel and is supported by a series of steel trusses. The bridge’s pontoons are constructed of reinforced concrete and are anchored to the lake bed with steel cables. The bridge also features a unique system of floating joints, which allow the bridge to move with the waves and keep the roadway level.

Maintenance and Upkeep

The Evergreen Point Floating Bridge requires regular maintenance and upkeep to ensure its structural integrity. The bridge’s pontoons are inspected regularly for signs of wear and tear, and any necessary repairs are made. The bridge’s steel trusses and other structural components are also inspected and maintained on a regular basis. The bridge’s lighting system is also regularly inspected and maintained.

Conclusion

The Evergreen Point Floating Bridge is an iconic piece of American engineering and a vital part of the Seattle area’s transportation infrastructure. The bridge is the longest suspension bridge in the United States, stretching 8,549 feet across Lake Washington. It is also the widest bridge in the world, with a total width of 116 feet. The bridge is a major tourist destination, offering stunning views of the Seattle skyline and Lake Washington. The bridge is maintained and inspected regularly to ensure its structural integrity.
