Employees have 357 telephone sockets at their disposal, which allow them to communicate with each other and between command posts located on masts.
The bridge is equipped with state-of-the-art sensors, such as anemometers, accelerometers, inclinometers and temperature sensors for measuring and detecting even the smallest movements of pillars, as well as measuring resistance for abrasion and tearing.
The toll point belonging to the viaduct is 4 km away from it, it has 8 lanes in each direction. The cost of building the facility with technical rooms, parking, control station and toilets was 20 million euros.
