Drinking Guangzhou morning tea in the morning, enjoying Zhongshan roasted pigeons at noon, and admiring the romantic Victoria Harbour at night are the daily itineraries of many residents in the Guangdong Hong Kong Macao Greater Bay Area. Since the release of the Outline Development Plan for the Guangdong Hong Kong Macao Greater Bay Area five years ago, the "1-hour living circle" in the region has gradually transformed from a development vision into a reality, and the accelerated connectivity of transportation infrastructure has provided strong support for sustained and rapid economic development. Taking advantage of the opportunities brought by policies and relying on regional and industrial advantages, the Guangdong Hong Kong Macao Greater Bay Area is attracting more and more people to integrate and take root in the bay area with convenient transportation conditions. In 2023, the total economic output of the Guangdong Hong Kong Macao Greater Bay Area exceeded 14 trillion yuan, accounting for less than 0.6% of the country's land area and creating one ninth of the country's total economic output. The cross river and cross sea passage has set up a "golden corridor". Currently, Hong Kong and Macao single license plate cars are performing a "northward" craze. "In the past, Shenzhen people used to travel to Hong Kong for consumption, but now, various complexes in Shenzhen are attracting Hong Kong people to come and consume." Mo Shunfa, Vice President and Secretary General of the Hong Kong Pinghu Association, said that some shopping malls in Shenzhen have a lot of people on weekends, and you can see many Hong Kong citizens' figures. The Hong Kong Zhuhai Macao Bridge has shortened the spatial and temporal distance between Guangdong, Hong Kong, and Macao, reducing travel costs for Hong Kong and Macao vehicles traveling north. In the first quarter of this year, the traffic volume of the Hong Kong Zhuhai Macao Bridge reached new highs, with the highest daily traffic volume exceeding 20000 vehicles. The cumulative passenger and vehicle flows entering and exiting the Zhuhai Highway Port via the Hong Kong Zhuhai Macao Bridge exceeded 6 million and 1.15 million respectively, an increase of 180% and 120% year-on-year. Both data sets a new historical high since the official opening of the Hong Kong Zhuhai Macao Bridge. This is a vivid portrayal of the "smooth traffic, prosperous people, and prosperous wealth" in the Guangdong Hong Kong Macao Greater Bay Area. The Guangdong Hong Kong Macao Greater Bay Area is increasingly showing a new scene of deep integration, as people, logistics, capital, and information flow are intertwined in both directions of going north and south. The the Pearl River Huangpu Bridge, Humen Bridge, Hong Kong Zhuhai Macao Bridge, Nansha Bridge, Guangzhou Shenzhen Hong Kong High speed Railway and other river and sea crossing channels that have been completed and opened to traffic in the Guangdong Hong Kong Macao Greater Bay Area, together with the Shenzhen China Channel, Shenzhen River Railway, Huangmaohai Sea crossing channel and Shiziyang Channel under construction, set up the horizontal "Yellow Gold Corridor" in the Greater Bay Area. Looking around, bridges spanning rivers and seas fly in the air, rows of urban rail and high-speed rail connect the bay area, and cars, trucks, and container transport vehicles run day and night... The three-dimensional transportation network of the Guangdong Hong Kong Macao Greater Bay Area is becoming increasingly dense, and a leading national highway and railway network has been built, with world-class port and airport clusters taking shape. "Hard connectivity" brings cities closer in time and space, and interconnectivity is the key to the development of the Guangdong Hong Kong Macao Greater Bay Area. From the opening of large-scale cross-border infrastructure such as the Guangzhou Shenzhen Hong Kong High Speed Railway and the Hong Kong Zhuhai Macao Bridge, to the acceleration of the construction of the Shenzhen China Railway and the Shenzhen Yangtze River Railway, "hard connectivity" is continuously narrowing the spatial and temporal distance of the Guangdong Hong Kong Macao Greater Bay Area. As of the end of 2023, the total length of highways in the Guangdong Hong Kong Macao Greater Bay Area is about 60000 kilometers, with a highway network density of 9.7 kilometers per 100 square kilometers. It is connected to four provinces (regions) including Guangxi, Hunan, Jiangxi, and Fujian with five or more highway channels, and has built a highway channel that radiates through the Pearl River Delta region in eastern and northwestern Guangdong. The Greater Bay Area on the track is more complete, with railway operating mileage exceeding 2700 kilometers and urban rail operating mileage of 1373 kilometers, ranking first in the world
