Several months after legislation to name the rainbow-arched so-called Waldo tunnel connecting the Golden Gate bridge to Marin County, the newly dubbed Robin Williams tunnel finally got official.

The tunnel's moniker, which was officially confirmed last June, was meant as a dedication to the late actor and comedian's life. Many thought that the tunnel's rainbow border was a natural reminder of his character Mork from "Mork & Mindy," who wore multi-colored suspenders on the show.

The $3,000 signs — one on each side of the tunnel — were paid for using private donations, as a Caltrans spokesman told SFGATE last summer.

The person who started the campaign to change the tunnel's name, Belvedere resident Julie Wainwright, posted a photo on Twitter of the new sign being installed.

The tunnel was previously unofficially known as the Waldo Tunnel because it is on the Waldo Grade, which is named after William Waldo, a Whig Party candidate who ran for governor in 1853.

"He was an integral part of our community here in the Bay Area," she wrote on the campaign's Change.org page last year. "We claim him as our own."

Williams was a Marin resident himself prior to his death in August, 2014.
