MWAA approved a $1 billion financing plan today to build a new North Concourse for US/AA regional jets.
Other changes will include converting level 3 (the current ticketing mezzanine) into a single security checkpoint. It seems that ticketing will move down to level 2 ("National Hall"), then pax will go upstairs for screening and walk across on bridges, then down into the piers. Bonus: you'll be able to walk between piers without leaving security.

The financing plan raises fees at DCA, and also directs $400M in DCA fees to pay down IAD's debts.
