The city’s weekly Friday night party is about to get bigger.

Oakland Museum of California is expanding its Friday Nights @ OMCA, closing down another half a street block and extending its hours until 10 p.m. Before, the party ran until 9 p.m.

“We really want to become the front porch of Oakland,” said Cynthia Taylor, the museum’s associate director of public programs.

From 5 to 10 p.m. Fridays, the museum will close off 10th Street next to the museum. It now will wrap the party around to the front of the museum, closing off one lane of Oak Street.

The additional space will let the museum add seven more food trucks, for a total of 20 from Off the Grid.

“The expansion is to honor the good weather and to make room for more people to enjoy what the Oakland Museum has to offer,” Taylor said.

On the museum’s Go Local Music Stage, a local DJ starts the music at 5 p.m. and the dance party begins.

“You have to see our toddler dance party. For the first two hours, every toddler in Oakland is out there shaking it,” Taylor said, laughing. “Everybody gets inspired that everything is going to be all right when they’re watching the toddlers.”

Everybody is invited to join the dance classes. Youth poets are showcased, and there are even old-fashioned games, including musical chairs and hopscotch.

“Oakland likes to play!” Taylor said.

A live band takes the stage later in the evening, with music until 9 p.m.

Local local beers, wines and nonalcoholic beverages are poured in the beer garden.

People of all ages can take part in free drop-in hands-on art workshops, held in the garden during the warmer months.

“Parents can have a drink while their kids are having a great time,” Taylor said. “Of course, we often see a lot of snappy adults getting their creativity on.”

Two lanes of Oak will stay open for traffic, and drivers will still be able to park in the museum’s garage on Oak, said Kelly Koski, the museum’s communications director.

The museum extends its gallery hours Fridays until 10 p.m., and admission is half-off, or $7.50 for adults. Museum members and those under age 18 are admitted free of charge.

The museum has four galleries. One has an art theme, another history and a third natural sciences. The fourth gallery showcases special exhibitions.

On the first and final Friday evenings of the month, the museum holds its Makers and Tasters Series. Local artisans have included Oakland breweries, tea masters, coffee roasters, authors and organic farmers, Taylor said. The series has talks, demonstrations and tastings.

“We love to feature Oakland’s best. We have an incredible range of talented people who have taken part,” she said.

The museum started its Friday Nights series three years ago, and it now attracts more than 3,300 every Friday. The extended hours will run through Oct. 28 to give people more time to eat, relax and hang out with friends and family, Taylor said.

“I love it that every generation of Oakland shows up. Friday Nights @ OMCA is popular, and we want to create more space so people can take their time,” she said.
