About the Open road tolling system:

It refers to a method of collecting tolls on highways without requiring vehicles to stop or slow down. Instead of traditional toll booths, open-road tolling uses electronic sensors and cameras to detect vehicles as they pass through designated tolling points.

 

About Orthotropic steel deck technology 

It is a construction method used in building bridges and other structures. It involves using steel plates that are specifically designed to be strong and stiff in one direction while being flexible in other directions. This allows the steel deck to support heavy loads, such as vehicles while remaining lightweight.
