The bridge was widened from 4.5m with 1 narrow lane to 14m with 2 lanes.

Temporary congestion

On the afternoon of July 8, at Lim Bridge 1, hundreds of vehicles were stuck in a line that stretched for more than a kilometer. Cars and motorbikes were crowded and stuck in a line, unable to move forward or backward. Many people had to find a way to escape the traffic jam by turning onto narrow residential roads.

Ms. NT T, living in lane 106 Minh Mang street, said: "Normally, it only takes about 15 minutes to get home from work, but that day, it took me an hour, going around many roads to get home."

The traffic congestion that lasted for hours made many people really need solutions from the authorities to organize temporary traffic in a more systematic and reasonable way.

Through investigation, the main cause of the congestion was the collapse of a culvert on the temporary road over the foot of the bridge. During the process of circulation, heavy trucks passing through this route damaged the drainage culvert below. When the culvert collapsed, the flow of vehicles could not circulate, leading to a serious congestion.

Cars drive on narrow roads to avoid traffic jams.

Immediately after that, the investor and the construction unit mobilized machinery and equipment to urgently repair the broken culvert, reinforce the roadbed and arrange for people to be on duty at both ends of the route to guide traffic in a more orderly manner. At the same time, they coordinated with the relevant agencies to install load limit signs to prevent large vehicles from continuing to damage the temporary road infrastructure.

The temporary route is currently opened through a small ravine, the terrain is lower than the bridge surface. In sunny conditions, vehicles can still travel relatively stably. In case of heavy rain, this route can be flooded, water flows rapidly through the ravine, the drain cannot drain in time, causing unsafety and potential traffic congestion. Therefore, to ensure traffic flow during the bridge expansion construction, timely and appropriate solutions are needed.

Need to reinforce and raise temporary road

According to the plan, the expansion of Lim 1 Bridge will be completed before the 2025 rainy season, but with the current erratic weather, it is difficult to ensure the plan. To avoid a repeat of the traffic jam, the investor and the construction unit have reinforced the road surface. However, it is necessary to upgrade the temporary road surface by spreading stones, pouring concrete or paving asphalt in weak sections; reinforce the drainage system below and raise the route to ensure no flooding during heavy rains.

In addition, it is also necessary to scientifically divide and regulate traffic by arranging regular forces to be on duty at both ends of the temporary road and key intersections to regulate traffic; have clear signs and directions to avoid vehicles moving spontaneously in the style of "each going their own way".

Investors and construction units also need to continue to coordinate with functional agencies to limit heavy-duty vehicles from passing through temporary roads or arrange suitable alternative routes; only allow small, compact vehicles to pass through construction areas to reduce pressure on temporary roads.

Expanding Lim 1 Bridge is a correct policy, in line with the people's wishes. Therefore, in addition to the efforts of the units, people also need to agree and raise awareness when participating in traffic to avoid overloading and congestion like recently.

Lim 1 Bridge is located on the main route of National Highway 49 connecting the center of Hue City to A Luoi District (old). This is a bridge with a very high volume of traffic; including large tourist vehicles and heavy trucks. The bridge has been widened from 4.5m with 1 narrow lane to 14m with 2 lanes, beautiful and airy.
