What is the speed limit when crossing a narrow bridge with good road conditions?

When crossing a narrow bridge with good road conditions, the speed should be controlled not to exceed 30 kilometers per hour. The following are the relevant regulations: 1. Roads without a center line: urban roads have a speed limit of 30 kilometers per hour, while highways have a speed limit of 40 kilometers per hour. 2. Roads with only one motor vehicle lane in the same direction: urban roads have a speed limit of 50 kilometers per hour, while highways have a speed limit of 70 kilometers per hour. When entering or exiting non-motorized lanes, crossing railway crossings, sharp curves, narrow roads, or narrow bridges, making U-turns, turning, or descending steep slopes, encountering fog, rain, snow, sandstorms, or hail with visibility within 50 meters, driving on icy, snowy, or muddy roads, or towing a malfunctioning motor vehicle, the maximum speed should not exceed 30 kilometers per hour. Among these, tractors, battery-powered vehicles, and wheeled special machinery should not exceed 15 kilometers per hour.
In all my years of driving, when encountering narrow bridges with decent road surfaces, I always keep my speed below 30 kilometers per hour. The reason is that visibility on narrow bridges is extremely poor. Even if the road is smooth, you can't predict if a car might suddenly appear from the opposite direction. Once, while crossing a bridge in the countryside, I was in a bit of a hurry and drove slightly faster, nearly colliding with an oncoming car—it gave me quite a scare. For safety, I always glance at the speed limit sign at the bridge entrance, as there's usually a specific sign requiring reduced speed. Additionally, on windy or snowy/rainy days, the bridge surface becomes more slippery, so driving even slower is safer. In short, it's much better to cross bridges slowly than to take risks. I recommend both new and experienced drivers to make this a daily habit.
As someone who frequently drives long distances, I'm very cautious about speed on narrow bridges. Good road conditions don't mean you can drive fast - I maintain a speed between 25 to 35 km/h. Narrow bridges often have only a single lane or insufficient width for two vehicles side by side, and slight acceleration can easily lead to loss of control. I've experienced this several times - when driving over 40 km/h, the car shook so violently that it almost scraped the guardrail. You also need to consider the bridge structure. Some old bridges may have new road surfaces but fragile materials, and high-speed passage may cause additional wear. My experience is to slow down in advance, roll down the window to listen for any unusual sounds, and make sure there are no other vehicles before crossing - this is the safest and most trouble-free approach.
I believe the speed should be reduced to below 30 km/h, which complies with traffic regulations in most areas. Narrow bridge entrances usually have speed reduction signs indicating specific limits like 20 or 25—don't ignore them. Good road conditions don't justify speeding, as the bridge's special design features such as railing height or curvature can increase risks. I'll pay attention to safe driving prompts, as slowing down improves visibility and helps avoid sudden accidents. Additionally, driving even slower at night or in fog ensures a smooth passage.
