Metro officials say the Takoma station will close at 10 p.m. on Friday and Sunday to allow investigators looking into last month's fatal crash to continue their work.

The station will be open all day Saturday from 7 a.m. to 3 a.m. as people travel to and from Independence Day celebrations.

Shuttle buses will be provided Friday night around the Takoma station.

Metro is planning to operate at near rush-hour levels Saturday from 4 p.m. to midnight. In a change from previous years, the Smithsonian station will be open. Free parking will be available for about 60,000 automobiles at Metro-owned facilities.

The transit agency warns riders to expect big crowds and says some red line trains may be offloaded to turn trains around.
