Designed by Jan Biliszczuk , a professor of engineering at the Wrocław University of Technology , the bridge 's design exceeded the length of the Solidarity Bridge in Płock by 30 m , then the longest bridge in the country . The contracts for the bridge 's construction were awarded to the Warsaw-based Mostostal consortium and its parent Spanish firm , Acciona Infraestructuras on 20 May 2008 , with construction commencing shortly afterwards . Construction of the bridge ( and its main A8 motorway ) continued for the next three years . Building efforts were temporarily halted during the 2010 Central European floods , but later resumed after a short delay
