- Tunnel's name was approved by the California state senate last year
- Williams used to live in Northern California

(CNN)A tunnel honoring Robin Williams has finally got its signs.
The tunnel -- which is located in Marin County, California, on the U.S. 101 freeway just north of the Golden Gate Bridge -- had its new name approved last summer by the California state senate.
The late actor used to live in Marin County.
"Robin was a one-of-a-kind type of person, and I want him to be honored in an unconventional, everlasting and beautiful way," Julie Belvedera said in a Change.org petition she launched that precipitated the senate vote. "This is just one way that we can do that."
Belvedera said the tunnel's iconic rainbow arches reminded some of the suspenders that Williams wore in his breakthrough role on the TV show "Mork & Mindy"
"We miss you, Robin," California Lt. Governor Gavin Newsom tweeted along with a picture of the new sign.
The $3,000 cost of the signs was covered by private donors, the California Department of Transportation told SFGate (the sister-site to the San Francisco Chronicle) last year.
