A new Muni platform in Mission Bay was unveiled in a ribbon-cutting ceremony on Tuesday.
The platform is located on 3rd Street between South Street, now known as Warriors Way, and 16th Street.
The SFMTA made a larger platform that will service both inbound and outbound trains.
SFMTA officials say the platform will allow for 700 riders at one time with four, two-car trains during events.
The Chase Center is scheduled to open in September and the first scheduled event is set for September 6.
As parking at the arena and in Mission Bay is limited, this will be the fastest and most reliable way to get to events.
