Freeways History, Design And More-minmi

Freeways: History, Design and More Highways that are exclusively designed for the use of traffic moving at higher speeds and ingress/egress regulation, is typically called a freeway. However, worldwide, these types of highways are also known as controlled-access highways, expressways, autobahns, parkways, autopistas, motorways, turnpikes and autostradas. These highways provide unhindered traffic flow, with no signals, property access or intersections. Motorists can enter and exit these highways via ramps. The History of Freeways The 1920s brought with them the modern highway. These highways were built in an effort to meet the needs of increased automobile use, faster travel times from city to city and improved roadways. Originally, these roadways were called dual highways; however, while these highways were divided, they hardly resembled the highways that we have in place today. The very first dual highway ran from Milan to Varese. It opened back in 1921 and had one lane for each direction of traffic and had no interchanges. The first highway to use a median strip in North America was the Bronx River Parkway, which was opened in 1924. In addition to medians, it also incorporated bridges so that intersecting streets could cross the highway without impeding traffic. Freeway Design Freeways do not have an at-grade intersection with railroads, other roads or trails. Very few freeways require drivers to stop for any form of traffic, but a few exceptions exist, such as that of the Interstate Bridge that forces motorists to stop when necessary for ships passing through. Crossing freeways is typically done with the implementation of other routes, such as overpasses or underpasses, footpaths, tunnels and footbridges. Access to these highways is provided using interchanges that are grade-separated. In the U.S., standard right in/right out is used to enter and exit the highway; however, there are some exceptions to the rule. For instance, changes to connecting highways may be placed on the left. Speed limits are also often higher for motorists on freeways, thus reducing the decision time; however, they are also equipped with guide signs, as well as being a great deal larger than the typical highway. Mileposts or mile markers are also placed along the freeway to indicate the mileage. This information is often used in the event of an accident so that emergency service personnel are aware of the location of the incident. Freeway Cross Sections In low traffic areas, it is not un.mon to see two-lane freeways. These types of freeways provide two traffic lanes for each direction and are frequently undivided. Other than these, freeways usually have a minimum of two lanes for each direction of traffic and can actually have as much as 16 total traffic lanes. Some highways are larger, but only in small stretches. San Diegos Interstate 5 is a good example of this, as there are actually 21 traffic lanes present for a length of two miles. Wider freeways often use express lanes in an effort to separate local traffic from through traffic. This is also true for carpool lanes, also known as HOV lanes.
