The main hall of Union Station closed at 6 p.m. for the beginning of earthquake damage repairs.
The hall will remain closed through the weekend and is expected to reopen by 6 a.m. Monday.
“We closed the main hall this evening as a precaution,” Union Station General Manager Mark Polhemus said. “Nothing is more important to us than the safety of Union Station visitors and workers.”
After the Aug. 23 quake, workers removed loose plaster from the ceiling and made temporary repairs. It was inspected for risks to the public.
But a small piece of plaster fell Friday, hitting a restaurant employee.
Signs and Amtrak and Union Station employees will direct people around the hall to where they need to go.
Netting to catch any other falling plaster was to be put in place Friday evening. Complete restoration of the ceiling begins next week.
The restaurant employee grazed by the plaster Friday was not injured.
