Police told office workers on Southwark Street and Thrale Street to leave shortly after 1pm, with sources saying it was "on lockdown".
The street has been cordoned off since the horrific ISIS attack, but office workers were previously able to sign in and out of work.
Seven people were killed and 48 were injured by evil jihadis Khuram Butt, Rachid Redouane and Youssef Zaghba on Saturday night.
One employee, who declined to be named, told Express.co.uk: "I had to queue for about an hour and a half to sign into work today.
"At about 1pm, the police came into the office and told us we had to sign out, which took about five minutes.
"We're now outside of the cordon. The police also seem to be evacuated the houses on Thrale Street."
