Drivers are advised to find alternate routes instead of using N. Fillmore Street, which is shut down between Wilson Blvd and Clarendon Blvd.
Dominion is installing a new 150,000 volt underground transformer at the site. It powers numerous businesses on the block.
Several of the businesses, including Palm Beach Tan and Cheesecake Factory, have posted signs on their windows apologizing to customers for having to temporarily close down.
There’s no definite time for the work to be finished, but the block is not expected to reopen any earlier than about 7:00 p.m.
