This morning’s shooting at the Washington Navy Yard snarled traffic, rerouted buses and even forced the closure of the Navy Yard Metro station for a time. With thousands of employees still sheltering in place, officials face the question of how to get folks out of buildings and on their way home this evening if the order is still in effect.

Metro officials said that the 92, 96, 90 and V7 bus routes that have been impacted by this morning’s shooting are likely to face delays throughout the afternoon due to street closures around the Washington Navy Yard.

Half a dozen K-9 units and six Metrobuses are assisting D.C. police.

Meanwhile, officials with the D.C. Department of Transportation said they are working on guidance to help employees in and around the Navy Yard area hoping to get home this evening.

“We’re trying to come up with a plan to accommodate the evening rush,” said Reggie Saunders, spokesman for DC DOT.
