Where's Marty: Behind the scene of Maryland State Highway Administration's radio room

The Maryland Department of Transportation's radio facility on Route 40 and I-695 is where the large informational signs you see statewide are serviced and fixed. Each sign has 36 LED panels that can display letters or numbers, which make up the message. Those signboards can also be manually changed from here. Pretty cool segment to be honest.
