Metro said it will not do any major track work and will open two hours early Aug. 28 when thousands of visitors are expected to attend a dedication ceremony for the Martin Luther King Jr. memorial.

The rail system will open at 5 a.m. and have “enhanced service on all lines,” Metro officials said. Parking will be free at Metro-operated lots. There will be no track work, even though Metro has launched an aggressive schedule of work on weekends.

Metro is encouraging riders to buy a farecard or a one-day pass prior to the event. Customers can also buy a special commemorative one-day pass for $9 that features an image of the MLK Jr. Memorial.
