VISION

LightRail is the world’s first subway-responsive light sculpture. By visualizing the real-time movement of underground trains along Market Street, it will transform San Francisco’s main artery into a scene of wonder and awe for millions.

Two LED strings in the center of Market Street will stretch two miles from Van Ness Avenue to The Embarcadero. The LED strands will be suspended safely above SF MUNI lines by anchoring into existing light post infrastructure. They will use BART and MUNI APIs to brilliantly illuminate the movement of underground trains. After BART and MUNI have closed, randomly distributed small pulses of light will move along Market Street, simulating the passage of pedestrians. The piece will thus be a celebration of the many sustainable modes of transit that make up city life.

IMPACT

LightRail will extend the energy of The Bay Lights into the heart of San Francisco. It will seamlessly connect the entire length of Market Street, crossing socio-economic divides. It will celebrate the 40th anniversary of BART and 100th anniversary of MUNI, which together transport over 300,000 riders daily.

The dazzling display of light will serve as a focal point and unite the many active efforts aiming to revitalize Market Street. LightRail will reinforce San Francisco’s image as a world-renowned center for artistic and civic engagement. It will serve as a model and inspiration for major cities all over the world.
