Europe's Three Countries Bridge that cost around £86 million allows tourist to visit three countries in a day.  

The award winning and the world's longest bridge spans across the Rhine River between France's Huningue and Germany's Weil am Rhein. 

Stretching 248m in length, the marvelous construction lies in Basel, Switzerland with its main span covering over 229.4m. 

It features no central supports in the water and stands as a testament to modern engineering and design, dedicated solely for the use of pedestrians and cyclists.

The bridge is the brainchild of visionary Franco-Austrian architect Dietmar Feichtinger and was inaugurated in 2007.

Travel enthusiasts who have ventured across this bridge have shared their awe-inspiring experiences online.

One visitor commented: "Great opportunity to walk to Germany, France and Switzerland in one day."

One traveller remarked: "The bridge itself is amazing. That such a large and expensive bridge was built solely for pedestrians and bicycles is enlightening."

They continued, highlighting the contrast between the sides: "The German side is very industrial, being a large port area. There is a very large, multicultural area that is bedecked with colour."
