The main routes from Guangzhou to Zhuhai are as follows: (1) Old Road: Guangzhou Avenue >> New Road of Luoxi Bridge (2): South China Expressway >> Don't worry, neither of the above two roads of Beijing-Zhuhai Expressway will pass through Jiujiang Bridge (that is, the South China Sea). However, other vehicles may be diverted and blocked. However, the South China Expressway is designed with eight lanes, which is very smooth on weekdays. The traffic of Luoxi Bridge is congested on weekdays. If you take a bus from Guangzhou to Zhongshan, it should not be affected.

I won't. Because Guangzhou won't pass Jiujiang Bridge when going to Zhongshan. The collapse of Jiujiang Bridge will only affect Jiangmen.

Traffic from Yangjiang to Foshan.

If you want to go to Zhongshan from Guangzhou

You should take the Beijing-Zhuhai Expressway.

It will not affect the traffic from Guangzhou to Zhongshan. Jiujiang Bridge is a bridge across the Xijiang River in China, located between Jiujiang Town, Nanhai District, Foshan City, Guangdong Province and Jiezhou, Heshan City, Jiangmen City, with a total length of 1, 682 meters. Total length of main bridge1370m, approach bridge length of 320m and deck width16m. The bridge adopts tower, beam and pier consolidation system, and the tower is 80 meters high (away from the deck). As a part of Guangzhan Highway of National Highway 325, this bridge is the first long-span prestressed concrete cable-stayed bridge with single tower and double-sided cables in Asia-Pacific region. The bridge was opened to traffic on September 28th 1985 and officially completed and opened to traffic on June 28th 1988. Designed by Guangdong Highway Survey Planning and Design Institute, it won the second prize of 1990 National Science and Technology Progress Award and the bronze prize of19/National Excellent Design Award. Guangdong Highway Engineering Office, Guangdong Highway Design Institute, Hunan Road and Bridge Company, Hunan Traffic Design Institute and Guangdong Traffic Research Institute jointly set up the "Yuexiang Jiujiang Bridge Project Contracting Company" to undertake the design and construction. The project cost is 99.8 million yuan, including 4 million yuan subsidized by the Ministry of Communications, another 5.4 million dollars borrowed from Guangdong Trust and Investment Company in foreign exchange (the exchange rate was different then), and 55 million yuan borrowed from China People's Bank and China Construction Bank. The rest of the funds will be fully raised by the Guangdong Provincial Communications Department, and then the bridge toll will be collected to repay the loan. At about 5: 00 am on June 15, 2007, a large sand carrier "Nanguiji 035" hit the pier of Jiujiang Bridge on National Highway 325, causing the bridge to collapse nearly 200 meters towards the southern end of Heshan, and two piers collapsed.
