ABSTRACT
ABSTRACT: The paper presents the major bridge crossings built to improve the road system in Szczecin, a city and sea port in northwestern Poland. Transportation problems had arisen following an increase in traffic and delays in the construction of a new bridge crossing on a major city route. Two crossings were constructed: the Regalica River Crossing on the major route and the Parnica River Crossing, which gives direct access to the sea port main gate. A wide range of spans and bridge types were used. For the largest spans, twin girder or box girder steel-concrete composite superstructures were built and for structures with limited depth, multi-beam composite superstructures were used. For the approach viaducts, reinforced concrete decks were utilized in the form of voided slabs, solid slabs or beam and plate.
