All remaining elements of the SR 520 Program from I-5 to Lake Washington are fully funded. These elements, known as the “Rest of the West,” will provide safety and mobility improvements for the region and reconnect local communities divided by the original construction of SR 520 in the 1960s. This map shows the key elements of the Rest of the West, which will be built in phases.
