Many "broken roads" have always been a major reason for the difficulty in driving in Nanning. According to the urban road planning of Nanning, Nanhu Tunnel is an important node in the "third vertical" of Nanning. Before the Nanhu Tunnel was opened to traffic, citizens encountered a "broken road" after driving from the extension line of Yuanhu North Road to Yuanhu South Road. South Lake is like a mouth. Qingshan Road and Xinghu Road can only face each other across the lake. Vehicles on both sides either take Shuangyong Road-Taoyuan Road-Education Road-Gucheng Road-Xinghu Road or Shuangyong Road-Minzu Avenue-Yuanhu Road. The traffic volume of these sections is very large, and it is even more congested when going to work, which greatly affects the smooth traffic between south and north in Nanning. With the opening of Nanhu Tunnel, the traffic pressure on Minzu Avenue, Shuangyong Road, Taoyuan Road and Xinghu Road has been greatly alleviated. The route from Qingshan Road to Xinghu Lake has been shortened from 20 minutes to 2 minutes, and the north and south are connected, and the whole journey of citizens is smooth.

In addition, in terms of improving Nanning's traffic network, the original design capacity of Nanhu Bridge is only 60,000 vehicles per day, but the current traffic flow has reached 890,000 vehicles, which is unbearable. After the opening of Nanhu Tunnel, it is estimated that more than 30% of vehicles of Nanhu Bridge can be diverted. At the same time, citizens can also go to wuxiang new district via Qingshan Road and Nanning Bridge.
