The Dr. Gridlock column at the Washington Post has a great comprehensive listing of road, highway and bridge closures for January 20, “Inauguaration Plan Walls Off Central Washignton” –
The plan that federal and local authorities announced this afternoon puts a virtual wall around central Washington on Jan. 20. Forget about the varying estimates on how many millions will show up for the inauguration. The restrictions in this plan tell us what we need to know about how bad a day it will be for commuters and spectators, and it will be very, very bad.
