One of the latest bridges in Budapest is currently under construction in district IX. It will connect the top peak of Csepel Island to the Hungarian capital’s circulation.
According to Pestbuda, the brand-new modern bridge will connect the Csepel Island, one of the largest islands on the Danube in Hungary, with the Pest side and will lead through an arched road right next to the National Athletics Centre in Budapest.
The 65-metres-tall pylon of the bridge which, as seen in the concept images, is the centrepiece of the bridge’s design, has been recently erected in its place.
The design of the bridge required some serious contemplation and eventually, the architects decided that the best solution was a curved bridge, which, if finished will be the only one-of-its-kind bridge in the Hungarian capital.
Pestbuda writes that the bridge will have relatively large dimensions for a pedestrian bridge; it will be 170 metres long and its tallest point will be the 65 metres tall pylon in the middle.
On another note, this modern bridge incorporates a few interesting architectural solutions. Due to the curved structure, the pedestrians will have a jaw-dropping view of the Danube, and the entire structure will be held via the pylon making this a cable-stayed bridge with an orthotropic deck.
However, unlike in many cable-stayed bridges, such as the Megyeri Bridge, the pylon the cables are connected to is not over the deck of the bridge but rather beside it. To achieve that, the pylon needs to be sloped at a 9° angle backwards.
The “needle” of the bridge was towed to the location upon a barge with additional equipment and construction materials weighing a total of 200 tonnes. The difficult part about erecting the pylon was that it could only be done at a specific water level.
Pestbuda highlights that calling the pylon a “needle” is quite accurate as the nearly 70-metres long structure towering 65 metres above ground level is only 2 metres wide in diameter at its widest point, tapering even narrower in both directions.
The deck of the bridge will be held with 53 cables in total, with them having a range of diameters between 35 to 65 millimetres. In addition, the needle-like pylon will be stabilised with 3 wide cables.
The deck is 7 metres wide (wider than the iconic Chain Bridge) and while it was designed for pedestrians and cyclists, it is capable to support small golf-cart-like vehicles transporting athletes in case of a sports event at the National Athletics Centre.
