Why is the "backbone" avenue of Vinh city often flooded?

Lenin Avenue, connecting with Xo Viet Nghe Tinh, is an important axis of Vinh City, with many agencies and offices, and a large traffic volume. This is also the route leading from the northern gateway of the city, especially connecting Vinh International Airport to the center... A two-way road with a wide and open landscape, but in recent years, whenever it rains heavily, this road is often flooded heavily and for a long time.

There are many concerns: Why is this route still heavily flooded during heavy rain while the North Canal cutting through this route at that time still had no high water level and normal flow?

According to Mr. Hoang Hong Khanh - representative of Vinh Urban Management Joint Stock Company, the reason why rainwater from Lenin Street connecting to Xo Viet Nghe Tinh (and other streets in general) is limited to draining into the North Canal at present is due to the lack of connection points to the canal (only 15 connection points/4 km on both sides). When renovating the North Canal, the connection is still in the current state. When heavy rain occurs, the water collection points and drainage ditches are overloaded. Lenin Street connecting to Xo Viet Nghe Tinh has a small 2-sided sewer system (1-1.5m) compared to the length from the airport to the width of the road, so it is not large enough to drain all the water when there is heavy rain in this 'basin'.

In the master plan of Vinh city, there is an 80m wide canal from Ke Gai river to Nghi Duc and then flows into Rao Dung river running parallel to 95m road to divert water for the entire Lenin road connecting to Xo Viet Nghe Tinh, but for many years there has been no investment capital for construction.

Regarding the garbage in the sewer, Mr. Hoang Hong Khanh said there was no blockage. The company had opened all the gates of the trash screen before the rainy season.

To reduce flooding for Lenin Street connecting to Xo Viet Nghe Tinh Street, according to Mr. Hoang Hong Khanh, it is necessary to survey and open more connection points to the North Canal and invest in building the above 80m canal according to the plan.

It is known that this 80m canal runs as follows: Starting point from Ke Gai River, Hung Dong Commune, flowing from West to East, through wards and communes of Hung Dong, Quan Bau, Ha Huy Tap, Nghi Phu, Hung Loc, Hung Hoa in Vinh city, to Rao Dung River and then flowing to Lam River - the end point, at Hung Hoa Commune.
