According to the Mayor's office, the process will start on Inauguration Day itself.
Deputy Mayor at the Executive Office of Mayor Muriel Bowser John Falcicchio tweeted on Wednesday saying crews will begin removing the barriers and fencing on major streets such as 7th, 9th and 12th starting at 6 p.m. Wednesday and working east to west.
He also says they will begin opening garages that were blocked as a precaution.
"This will take some time," Falcicchio said in his tweet. "Give crews time and space to work safely."
He says the process will likely take about 36 hours, which aligns with the end of the inauguration pause on indoor dining, which expires on Friday at 5 a.m. At that time, restaurants in the District will be able to return to indoor dining at 25% capacity.
