Iraq's population is largely urbanized, its health care system is relatively advanced and it has much more than Afghanistan in terms of highways, electricity grids and telephone networks.
On Thursday, my colleagues Matthew L. Wald and John Schwartz explained how a summer of ferocious heat, drought and storms, probably exacerbated by a warming climate, have taken a costly toll on the nation's infrastructure, including airports, highways, power grids and transit systems.
How would you evacuate from there?" Mr. Khidekel said that three construction systems fortify the Vertical Highway: a standard grid of beams and columns, suspension cables, and a DNA-like spiral of roadways, from which the structure gets its name, forming a kind of fishing net impervious to collapse.
We could certainly use a bunch of high-speed trains, a smart electric grid, highway and water-main upgrades and so forth, but only government can pay for those things, and to do that, you have to either tax or borrow.
However, in our simulations, the focus has been mainly on applying this method on typical straight (highway) or Manhattan grid scenarios (urban).
Not geographically correct highways in the grid, mind you, unless LOS ANGELES (where I-5 and I-10 intersect) has suddenly migrated to the East Coast without telling anyone.
As we fight to curb unacceptable rates of unemployment, these bonds permit our mayors and governors to engage in strategic borrowing, investing and bonding to repair our highways, bridges, electrical grid, ports, airports, levees and dams.
Schools, highways, the electric grid, water systems, ports, dams, levees — the list can seem endless — have to be maintained, upgraded, rebuilt or replaced if the U.S. is to remain a first-class nation with a first-class economy over the next several decades.
Like the interstate highway system, a national grid could eliminate bottlenecks and encourage competition.
