HCM City 39 years after Reunification Day Thirty nine years after reunification on April 30, 1975, HCM City has changed substantially into a modern, dynamic city.  Since reunification, HCM City authorities have much invested into the development of the city’s infrastructure to accommodate fast socio-economic growth. One of the outstanding infrastructure works of the city is Hanoi Highway, which was previously known as a route linking Saigon's urban area to the North. Now, the highway has become one of the most important gateways to HCM City, linking the city with southeastern areas, the Central Highlands and the North.   Hanoi Highway Due to the high traffic levels, the route has been upgraded many times. Some parts of the highway have been expanded to 120 metres wide. It is among the largest road projects in HCM City. The East-West Highway is also a big transport work. Thirty years after the reunification, National Highway No. 1 was the only route to transport goods from north to the southwestern region through HCM City. However, the route deteriorated over time, causing many traffic accidents. The East-West Highway was built to deal with the problem. The highway includes the Thu Thiem Tunnel.   East-West Highway To ease traffic at peak hours, HCM City authorities built a number of overpasses including Cat Lai and Tram 2, along with tunnels such as Tan Tao and Linh Trung.   The city has upgraded Nhieu Loc-Thi Nghe and Benh Nghe-Tau Hu canal routes which were seriously polluted and lost their capacity for traffic in the 1980s   Phu My and Thu Thiem Bridges help connect the central HCM City to Thu Thiem Peninsula to the east Nhieu Loc-Thi Nghe Canal revived The city’s symbol Thu Thiem Tunnel   Saigon's Notre-Dame Cathedral     Intersection from above      Robust development in HCM City suburbs        Many modern infrastructure projects  By Tung Nguyen, dtinews.vn
