California high-speed rail: With an initial budget of $40 billion, the rail system, which spans 1,300 kilometers (808 miles), will link Southern California and San Francisco. High-speed electric trains will transport an estimated 10,000 passengers daily, with travel time from Los Angeles to San Francisco taking only less than three hours at 320km/hr. Although the project is currently facing delays, Californians are still hopeful that the rail system will be operational by 2030. 

Beijing Daxing International Airport: There is no shortage of megaprojects in China. In fact, industry observers note 30 ongoing infrastructure projects that are set to reshape the world. One of these is the Beijing Daxing International Airport. With a proposed budget of $13 billion, the airport will feature seven runways and the world’s biggest terminal, which, when fully operational, can accommodate 72 million travelers annually. 

Dubailand: The $64 billion entertainment complex will rise in Dubai, United Arab of Emirates, which was touted as the most ambitious leisure project when it was first announced in 2013. And just how big this project is? Dubailand will be in a 278 sq.km complex, enormous enough to accommodate three Walt Disney Worlds. Upon its completion in 2025, Dubailand will feature theme parks, sports venues, health facilities, a hotel with 6,500 rooms, and a 10 million sq.ft mall.

South Korea’s Lotte World Tower: The Fifth Tallest Skyscraper In The World

South Korea has entered the list of countries with the tallest buildings as Lotte World Tower opened its doors to the public. Built by Kohn Pedersen Fox Associates and Lotte Engineering and Construction, the Lotte World Tower is a 123-storey structure that has taken six years to complete. The skyscraper is set in the heart of Seoul’s elite business hub in Jamshil. The construction of the building cost $3.5 billion.

The Seoul skyscraper is known for its smooth, tapered-glass exteriors. It houses luxury shops, high-end corporate offices, stylish apartments, and a seven-star hotel. The Lotte World Tower is also open to tourists and locals with its observation deck and gallery, overlooking Seoul City. The inclusion of Lotte World Tower in the list of the world’s top 10 tallest buildings has bumped off Malaysia’s Petronas Twin Towers.

Lotte World Tower has its share of controversies, too. In 2014, Seoul’s locals were puzzled with the discovery of sinkholes near the construction site, noting that it might not be safe for the public after it is put into completion. But the construction of the skyscraper continued despite great public opposition.

The Sydney Metro Project is currently the largest public transport project in Australia. It is expected to cost more than $12.5 billion, which will deliver 31 metro stations, including new ones in Victoria Cross, Crows Nest, Waterloo, Central Station, and many others. It will also create 65 kilometers of new metro rail infrastructure that will span from Bankstown in the south west part of the city to Rouse Hill in the north west.

The entire metro rail system is expected to begin operations in 2024, however, the first stage of the project, the Sydney Metro Northwest, is due for completion in the earlier part of 2019. The tunnels have already been constructed, as bridges and other civil works are expected to be finished ahead of schedule.

When finished, the project will revolutionize commuting in the most populous city in Australia. The Sydney Metro rail system will provide travelers world-class, efficient, safe, and reliable trains, and strategically located stations.

Additionally, the technology that will be implemented will benefit customers greatly as they would have no more need to rely on timetables. The train service frequency will be every four minutes during peak hours, reducing waiting time. Travel apps will also be developed to allow customers to plan at home how they will commute. Real-time journey information will also be posted at the metro stations and on board the trains.

Tunneling Through Hurdles Faced By Melbourne's Metro Train Project

Melbourne's 10-year metro tunnel project is a giant leap forward as the government heeds the travel woes of the city's commuters. Engineers are already drafting solutions to some of the most difficult aspects of the tunneling project.

Unstable soils are a problem throughout most of the locations where the tunnel will be built, including the silt soil at Arden and sandy ground at Domain station. Until now, engineers are working out the most effective designs for the tunnel to hold against the porous grounds of Melbourne, making the project one of the most difficult engineering endeavors of the city.

Perhaps the most glaring challenge is tunneling beneath the Yarra River, whose river bed is mostly a mix of basalt, silt, and clay. The presence of aquifers adds to the complexity. After careful study of alternative methods, engineers had elected to use Tunnel Boring Machines to minimize the construction's impact on the river and surrounding areas.

Contractors are also working out methods to avoid adversely affecting road traffic, existing public transit lines, and pedestrians aboveground given the extensive time to complete the project. The government, however, is unfazed despite the formidable road ahead; it has already committed 10.9 billion dollars for the project's completion.

Iconic Landmarks: Four Bridges Worth Visiting

Bridges are landmarks contributing to a city’s charm and history. The visions behind the construction of these structures were also grand, and captured the prevailing aesthetics of the era. Below are four breathtaking bridges worth visiting:

1. Golden Gate Bridge (San Francisco, United States)

The famous red bridge can be seen in countless postcards and other souvenirs, thus earning the record as the most photographed bridge. Opened to the public in 1937, this bridge serves as the West Coast’s landmark. Over 40 million vehicles pass by the bridge yearly.

2. Tower Bridge (London, England)

This bridge built in the 19th century is made out of two towers, with its upper level joined by walkways. Most tourists mistakenly take this for the London Bridge, which is much simpler than this architectural marvel. The Tower Bridge got its name from the Tower of London on the other side, which hugely influenced its design.

3. Millau Viaduct (Millau, France)

This is the tallest structure in France with a height of 1,125 ft. Finished in 2004, the bridge has four lanes and spans the valley of the River Tarn near Millau. The aim of its architect, Lord Foster, was to create a delicate-looking bridge that doesn’t obstruct the breathtaking views of nature. The effect is intended to make the bridge look like it’s floating on clouds.

4. Sydney Harbour Bridge (Sydney, Australia)

The Sydney Harbour Bridge is the world’s largest steel arch bridge. It is also nicknamed “The Coat Hanger” for its design and provides a good backdrop to the majestic Sydney Opera House. The bridge carries roads for vehicles and pedestrians from the North Shore to the Sydney central business district. Every New Year, fireworks decorate the view of the Sydney Harbour Bridge and skyline, a view the whole world looks forward to witnessing.

A Commuter's Guide To Overcrowded Subways

In an effort to reduce the number of cars on the streets, cities turn to the improvement or development of public transportation. One of the more common means of transport is the subway system, a network of underground trains that can stretch for miles. These subways connect cities and allow travelers to reach their destination in a short amount of time.

An unexpected outcome of successful public transportation projects is overcrowding. As much as local governments try to build more trams and coaches to accommodate commuter traffic, many major cities are overwhelmed by their own populations. Uninitiated commuters could get lost and confused in a maze of people and be discouraged to take public transport altogether. New commuters, in particular, would do well to abide by these suggestions:

Learn rush hour times: Commuters should know when rush hours are. It is typical for subways to be extremely crowded during these times. These can be extremely dangerous times, especially if one suffers from asthma, claustrophobia, or any condition that could be affected by being around lots of people. It may be considered a hassle, but a few hours before or after rush hours are safe windows for commuters to avoid crowds.

Know the stations: Sometimes it is inevitable to commute during rush hours. In these cases, commuters are advised to learn how each station fills up. Some stations are bigger than others, and are not so bad even when filled with people. These are normally situated in bigger cities or areas. Overcrowding cannot be avoided but at least the commuter will have a better chance of getting inside the train first.

Modern city planners are still figuring out ways to improve the subway system so that overcrowding is no longer an issue. In the meantime, these professionals suggest commuters also strategize with their routes to lighten the daily commute.

The Advantages Of Using Public Transportation

For most people, traveling to and fro via public transport is cheaper. But a lot of people still think using private cars is the wiser option. While owning a car may seem like a sound investment, using public transportation has a lot of benefits, too. 

Public transportation is safer than driving one’s vehicle

 

Public transportation-related accidents are just one-twentieth of the total road fatality rates. Car accidents account for approximately 40,000 deaths and injuries in just one year and is considered as a common cause of death for people below 44 years old.

Public transportation is convenient

 

There’s no need for the commuter to look for a good parking spot going to school or work because public transportations like subways and buses take them there without the hassle of looking for parking. Commuters also don’t have to worry about driving to their destination because someone else is doing it for them. 

Using public transport makes people physically active

 

People using public transport are more active physically because they walk and move more than the car owner. Brisk walking lowers a person’s risk for various diseases like stroke, heart conditions, back problems, and even depression.
