Bike Above Bertha

Bike Above Bertha

Join us for a free public bike tour that follows the route Bertha took beneath downtown Seattle (from above ground, as best as possible). This tour provides a unique way of viewing and understanding the historical, archaeological and engineering aspects of the SR 99 Tunnel Project.
