On August 2, 1873, inventor Andrew Smith Hallidie personally gripped the very first cable car down Clay Street in San Francisco. On the actual 150th anniversary of that date, history reenactors will evoke that event on the flagship of today’s cable car fleet, Powell Street Cable Car 1, at the turntable at Powell and Market Streets, adjacent to Hallidie Plaza, starting at 10:30 a.m. They’ll ride the car to Aquatic Park (Hyde and Beach Streets), where they’ll celebrate again. Join civic dignitaries, business and neighborhood leaders, and San Franciscans of all ages in cheering this special day. Because the cable cars have been part of the San Francisco scene for 15 decades, feel free to come dressed for YOUR favorite decade, and snap a shot of yourself next to an actual Powell Street cable car painted in the accurate throwback livery of that decade.
