Los Angeles Mayor Eric Garcetti on Monday announced the launch of Metro’s Silver Line Express.

The new bus service aims to make it easier for commuters traveling between downtown Los Angeles and San Pedro. The travel time will now be about an hour without anyone needing to have a transfer, according to Garcetti’s office. The cost to ride is $2.50 one way, according to Metro.

“Expanding the Silver Line saves time for commuters, connects people to communities, and links workers to jobs,” Garcetti said in a statement.

The new service offers a rush-hour, weekday, Silver Line Express –

– called 950X, that will save commuters up to 20 minutes a trip compared to driving on Express Lanes during the week on the 110 Harbor Freeway.

The other line, the Silver Line 910, will travel every half hour the same route every day, but it will have more stops and be available to riders at night, on weekends and during off-peak hours. It will replace another line that ran once an hour.

Lorena Parker, executive director of the San Pedro Historic Waterfront Business Improvement District, said the organization is excited about the Silver Line coming to San Pedro.

“It will provide an easy way to get to the San Pedro tourist attractions such as the USS Iowa and Ports O’Call,” Parker said. “Furthermore, it will open up exciting new opportunities for people working in downtown to live near the L.A. Waterfront. It’s also about half the cost of driving alone in the FasTrak lane.”

As part of the launch, the Battleship Iowa Museum will offer free admission to Metro riders from now through Jan. 31.
