Interstate Highway


 

The Dwight D. Eisenhower National System of Interstate and Defense Highways, commonly called the Interstate Highway System, is a network of highways in the United States. The Interstate Highway System is a separate system within the larger National Highway System. With very few exceptions, Interstate highways are controlled-access freeways, allowing for safe high-speed driving when traffic permits. They are assigned a special level of funding at the federal level. Despite this federal funding, these highways are owned, designed, built and maintained by the state in which they are located, with the only exception being the federally-owned Woodrow Wilson Bridge on the Capital Beltway (I-95/I-495).

The highways in the system are typically known as Interstate XX or I-XX; sometimes Interstate Highway XX (IH XX) or Interstate Route (IR XX) is used. In some areas the more generic Route XX or Highway XX is used. The system serves practically all major U.S. cities, and unlike its counterparts in most industrialized countries, often goes right through downtown areas rather than bypassing them. This facilitated the emergence of automobile-oriented postwar suburban development patterns, often pejoratively referred to as "urban sprawl".

The system is prominent in the daily lives of most Americans. Virtually all goods and services are delivered via the Interstate Highways at some point. Many residents of American cities use the urban segments of the system to go to and from their jobs. Most long-distance journeys (for vacation or business) of less than 300 miles (500 km) use the interstate highway system at some point.

Hawaii has several signed Interstates, but Alaska and Puerto Rico do not. The latter two do have roads designated as Interstates for funding purposes, but they are not currently or planned to be built to Interstate standards. The public controlled-access highways of Puerto Rico are the Autopistas (PR-22, PR-52, and PR-53).

India's superhighway

Marilyn sez, "In a country that until recently had barely 1,000 km of 4-lane roads, with more potholes than roads, suddenly there's the magical Golden Quadrilateral superhighway, linking Delhi, Mumbai, Chennai, and Kolkata. 'Much as the U.S. interstate highway system mobilized American society and grooved the postwar economy, India hopes the Golden Quadrilateral will push the country's economic engine into overdrive?bringing the benefits of growth in its booming metropolises out to its impoverished villages, where more than half the population lives.'" As the priest works his way down a long line of vehicles, Menaka's older brother Dhana lights a coconut, circling the motor scooter three times with the smoking husk before smashing it to bits on the pavement in front of the scooter. He places a lemon under the front tire, which Menaka will try to crush when she rolls forward, a most auspicious beginning. "Do you have a driver's license?" I ask her. "No, sir, no," she giggles. At that moment Mr. Deekshith appears and drapes a garland of yellow flowers over the scooter's handlebars. He sprinkles holy water from the shrine of Lord Ganesh over the bike while reciting a mantra from the Hindu Vedas, and finishes by flicking droplets of red kumkum, an extract of turmeric, over the front of the scooter and dabbing a bit onto Menaka's forehead. In thanks, Menaka hands him a gift bag of bananas and turmeric powder. Then she starts the ignition and guns the engine. She seems briefly baffled by the controls (Which one, again, is the throttle? Which one is the brake?) and struggles to keep the bike upright once she's pushed it forward off the kickstand, crushing the lemon to raucous cheers from Dhana and other onlookers. An auspicious beginning, but it looks as if she might keel over sideways into the traffic rushing by a few feet away. Alarmed, I grab hold of a handlebar. "Do you have a helmet?" I shout over the sputtering engine. She shakes her head, grinning. "Do you know how to drive?" "No, sir, not really," she shouts back merrily, "but I'm planning to learn!" With that, she jerks forward, peeling rubber as Dhana races alongside and nearly gets clipped by a passing car. She accelerates and plunges into the madness of evening rush hour in Bangalore with only Lord Ganesh to help her. As she passes under distant streetlights, I can just make out the top of her head bobbing along in the seething current of 21st-century India, one more swirling pinpoint in a moving river of light..." Fast Lane to the Future (Thanks, Marilyn!)...
