Millions of pounds of military hardware are expected to roll down the US capital's streets in less than two weeks, fulfilling a dream of President Donald Trump but also sparking concerns about how the roads of Washington, DC, will fare under the literal weight of heavy tanks and fighting vehicles. The largest military parade the city has seen in decades is expected to bring seven million pounds of vehicles and weaponry as well as a price tag potentially in the tens of millions of dollars, and this week the US Army has started reinforcing the roads that will carry the hardware downtown and along the parade route.
