Robin Williams finally gets official tunnel tribute

Robin Williams fans now have a real-life memory lane. 

Robin Williams' name to adorn Marin County tunnel

Following last year's unanimous vote by the California State Senate, officials have formally dubbed the tunnel north of the Golden Gate Bridge Robin Williams Tunnel in commemoration of the beloved actor, comedian and longtime Bay Area resident. Signs were erected to officially mark the passageway on Monday. As USA TODAY previously reported, the $3,000 signs were privately funded.

Sarah Michelle Gellar, who played Williams’ TV daughter on the CBS sitcom The Crazy Ones, hailed the tribute on Instagram. “I guess I know who is on the other end of the #rainbow#robinwilliams,” Gellar wrote in reference to the tunnel, noting, "It's the former Waldo tunnel in SF."

Per SFGate, residents previously referred to the U.S. Highway 101 tunnel as the Waldo tunnel because it cuts through the Waldo Grade. Its famed rainbow arches invoked memories of Williams’ multi-colored suspenders on the sitcom, Mork & Mindy, prompting Belvedere, Calif., resident Julie Wainwright to campaign for a name change following the actor's death nearly two years ago.

Wainwright also celebrated the change on social media. "It is official. You can now drive through the Robin Williams Tunnel when going to/from Marin and San Francisco," she wrote, later adding, "Remember Robin."
