Bridges are essential as they are often popular landmarks for tourists, not to mention the obvious purpose of safely connecting two areas. So, you can only imagine how important it is to design lighting for bridges.
If you are part of the bridge lighting project and don’t know where to start, then you are at the right place. Here we have listed the most important things you must consider when lighting a bridge based on modern trends.
Safety and Security
Bridges are pivotal to transportation, so special consideration is needed when lighting them. Ensure the pedestrian path and driveway are correctly lit to avoid accidents. The US Department of Transportation recommends lighting the bridges in a way that doesn’t cause glare or eye strain upon approach.
Without proper lighting, there is also a risk of accidentally falling off the bridge. Handrail lighting is perfect for this. Security is also a major concern when it comes to bridges.
By installing high-intensity flood lights, you can deter most criminal activity, making the place much safer for the citizens.
Keep in mind that lighting for utility and aesthetics are two different things. More on it later.
Bridge Lighting Requirement
Bridge lighting requirement depends on the type, purpose, and environment the bridge is present in. A bridge for pedestrians and cyclists has different lighting requirements than one with heavy traffic.
Typically, lighting is measured in “lux,” which means lumens (light intensity) produced by a source to light up an area of one square meter.
Experts recommend 1 to 5 lux of illumination for pedestrian paths. For bridges that host heavy traffic, it’s best to have 5 to 10 lux of illumination. Accidents and mishaps can be avoided with at least this lighting level.
You also have room to be creative with colors and temperatures. Interestingly, red and green colors are avoided for the bridges above water because these act as a signal in ship navigation.
Proper Placement
Bridge lighting is tricky because the structure already holds tons of weight of people and vehicles moving across. To keep the structure’s integrity, you must use existing foundations and studs. Moreover, lighting maintenance costs become too expensive if the placement is not well thought off.
There are no definite rules for bridge lighting placement. However, there are some important things a lighting designer must consider.
- Make use of existing columns and foundations. This ensures ease of maintenance in the future.
- The lighting beam angle should be between 60 to 120 degrees—This will prevent light spillage and unnecessary diffusion.
- Place Handrails at least 2 to 3 meters apart. The same goes for post-lights as well.
Bridge Lighting Installation
The bridge’s structure isn’t like that of a building, so it needs special consideration. Bridges withstand cyclic vibrations and stress all the time. Moreover, the outside wind, humidity, and heat also adversely affect the structure. All of these factors have a significant impact on life span as well.
Make sure to install high-quality luminaire that can withstand such stresses and weather. But what is considered high quality when it comes to lighting? This brings us to the next section.
Must Choose Durable Lights
Protection ratings define the quality and durability of lighting fixtures. Lighting fixtures certified with specific standards and ratings should be used for bridge lighting.
| Quality Standard of Lighting Fixture | Meaning |
| IP60 and IP66 Rated | Ability to withstand high water exposure, mist, and dust. E.g., rainfall and dust storms. |
| 3-G Vibration Rated | Ability to withstand heavy bridge vibrations and stress. |
| IK08 and IK10 Rated | A European standard equal to the international standard IEC 62262 shows protection against external mechanical impact. |
| MIL-STD 810G Rated | A military standard that certifies lights against shock, impact, and extreme temperatures. |
Environment-Friendly Lights
Since bridge lighting is open to the environment, you must consider its effects on nature. Studies show that artificial lighting on bridges above water significantly impacts the aquatic life beneath it.
The same is true of birds and animals that live on the land and trees near the brightly lit bridges. All these have negative ecological effects which need to be considered before lighting design. It would help if you also used LED luminaires instead of traditional lights as they are highly energy efficient. They also require less repair and replacement, reducing the carbon footprint.
Types of Bridge Lighting Fixtures
Many fixtures are available to glow up any style of bridge, making it a spectacular tourist attraction.
Lighting Technologies
Before going further, let’s discuss the type of lamps available for bridge lighting. Previously halogen, metal halides, high-intensity discharge (HID), and high-pressure sodium (HPS) lights were common choices for bridges.
However, light-emitting diodes (LED) are preferable for modern lighting. Halogens and HPS produce an amber-yellow color and are used in lighting streets.
HID produces higher lumens, and the light is much whiter. However, it takes a minute to warm up once turned on. The light beam is also omnidirectional in older technologies with larger beam angles.
HID and Halogens also consume high power, which leads to a massive waste of energy. These drawbacks increase over time, and your project may have higher operational costs.
Modern LED lamps are improving every day and offer better bridge lighting solutions.
Post Lights
Post lights or lamp posts are lighting fixtures mounted on a pole and are commonly used for bridge lighting. The fixtures are available in many designs, such as Victorian-era lanterns or modern-day shoe box lighting.
Handrail Lights
Handrail lights are installed inside the guide rail meant for pedestrians and cyclists. Handrail lighting creates charming vibes and makes the pathway much safer. Since these lights direct downwards, the light doesn’t escape into the sky, making them more efficient.
Floodlights and Spotlights
Floodlights and spotlights are great for highlighting certain architectural features of the bridge. These lights can be installed above as well as below the bridges.
Neon Lights
Neon lights are decorative bridge lights. Designers use these to get creative and make unique artistic bridge lighting projects. LED neons are the go-to choice of designers.
Wall Washers
Wall-washing luminaires are best used to highlight a bridge’s texture or architectural marvel.
Aesthetically Pleasing Lighting
The next most crucial aspect to keep in mind is that bridge lighting needs to be not only practical but also aesthetically pleasing. You must remember the place’s history, heritage, and culture to master bridge lighting.
An aesthetically pleasing bridge lighting can make an ordinary bridge a popular tourist attraction driving the local community’s economy.
Smart Lighting
Modern LEDs have intelligent control that lets the user control many lighting features, such as dimming, colors, and temperatures. This feature has allowed it to conduct majestic kinetic lighting shows on bridges. Moreover, smart lights are programmed to turn ON/OFF in sync with sun rise and fall.
Exciting Bridge Lighting Design Ideas
There are a lot of lighting designs that can bring out the best in any bridge architecture. Lighting designers typically make use of architectural features and themes to light bridges. Here are some popular bridge lighting ideas for your project.
Under Bridge lighting
Under the bridge, lighting is done using flood lights that highlight the features present at the bottom of the bridge. Arcs under the bridge look spectacular under proper lighting. The view becomes more phenomenal if the bridge is above a river or sea.
Pedestrian Bridge lighting
Handrail lighting for pedestrian bridges is trending. It creates a beautiful visual and doesn’t let the light escape the sky.
Lighting Based on a Theme
Bridges are excellent for theme-based decoration. Whether it’s New Year’s Eve, Christmas, or valentine’s day, you can use this to create a pretty lighting display. Modern LED allows designers to choose lighting with multiple colors and fixtures. Moreover, LED strips and neon are the best tools for lighting artists.
Lighting Representing Heritage
Not everything needs to change with time. Heritage is an essential aspect of any culture and makes it unique. Bridge lighting preserving the local heritage can act as a sneak peek into the past, which is exciting. Nowadays, retro and vintage fixture designs installed with modern lighting lamps are an excellent combination. Such type of bridge lighting can turn a boring place into a historical landmark.
Creating Focal Point
We all have seen different types of bridges in our life, and each style has its unique characteristic. Like arch bridges have graceful arcs underneath the bridge. Similarly, suspension bridges have attention-grabbing wires holding the structure. By highlighting such features, you can create a focal point that can improve your bridge lighting project.
