Isn’t it remarkable how engineering feats can also be works of art? The \u017eelezni\u010dn\u00ed estak\u00e1da Sluncov\u00e1 is a testament to that.
This railway bridge is more than just a way to cross from Praha hlavn\u00ed n\u00e1dra\u017e\u00ed to Praha Libe\u0148. It is a vital part of Prague’s New Connection. This project aimed to boost railway capacity. It also sought to simplify connections between Prague’s main stations.
Completed as part of the Nov\u00e9 Spojen\u00ed, the \u017eelezni\u010dn\u00ed estak\u00e1da Sluncov\u00e1 quickly gained recognition. In 2008 it won the Bridge Structure of the Year award for new constructions. Skanska proudly constructed it. The award considered project quality. It also took into account the bridge’s execution and aesthetic appeal.
The \u017eelezni\u010dn\u00ed estak\u00e1da Sluncov\u00e1 boasts a continuous beam design. It features eight spans. The longest span stretches 47.6 meters. The entire structure measures 323.8 meters. Its construction used reinforced and prestressed concrete. This ensures durability and strength. The cross-section reveals a double-walled chamber beam. It has an oval shape and three internal cavities. This design provides exceptional structural integrity. The \u017eelezni\u010dn\u00ed estak\u00e1da Sluncov\u00e1 maintains a constant height of 2.7 meters. It has a width of 14.5 meters.
The \u017eelezni\u010dn\u00ed estak\u00e1da Sluncov\u00e1 rests on large diameter piles. They are 1.2 meters wide. Their lengths vary from 9 to 16.5 meters. The pillars have variable elliptical cross-sections. This adds to the bridge’s unique design. The bridge’s supporting structure was built on a fixed frame.
The \u017eelezni\u010dn\u00ed estak\u00e1da Sluncov\u00e1 allows trains to cross. It avoids disrupting traffic below. The bridge also features expansion joints. These manage the bridge’s movement due to temperature changes.
The \u017eelezni\u010dn\u00ed estak\u00e1da Sluncov\u00e1 includes a 2.4-meter wide concrete sidewalk. There is also a 1-meter wide sidewalk. The track bed is made of gravel. It is 9.6 meters wide. The minimum gravel bed height is 643 mm.
This bridge cost 262.3 million Czech crowns. That is about 49400 crowns per square meter. Spr\u00e1va \u017eelezni\u010dn\u00ed dopravn\u00ed cesty was the investor. Pontex Praha designed the bridge.
The \u017eelezni\u010dn\u00ed estak\u00e1da Sluncov\u00e1 stands as a modern marvel. It combines engineering excellence with aesthetic design. As trains rumble overhead consider the intricate details. Think about the planning that brought this structure to life. It is not just a bridge. It is a symbol of progress. The \u017eelezni\u010dn\u00ed estak\u00e1da Sluncov\u00e1 is a testament to human ingenuity.
