Textual content description supplied by the architects. The footbridge, which is located within the metropolis’s recreation space, connects the river’s left financial institution with the island of Bölesholmarna and hyperlinks as much as a small bridge bridging the arm of the river. The footbridge connects pedestrian and bike owner trails located alongside each river’s banks; it additionally carries electrical and communication cables.

The footbridge consists of a prestressed concrete deck of 1 span of the size of 179.00 m, which is suspended on two inclined suspension cables of three spans of lengths of 28.80+187.00+29.50 m. The bridge deck has a variable width – from 6.40 m in the course of the bridge to eight.40 m on the abutments. The utmost sag of the cables is 20.90 m. The bridge deck is assembled of 59 three-meter-long prefabricated concrete segments and two monolithic finish cross members.

The streamlined cross-section of the bridge deck consists of solely 400 mm deep edge beams and a 140 mm thick bridge deck slab. Every phase is strengthened by ground beams on the joints. Two suspension cables include 2×55 mono-strands grouted in metal pipes of 273 mm diameter. The deck is repair related with suspension cables in the course of the bridge.

The 30.25 m tall pylons have the form of the letter A. The pylons’ legs, that are inclined longitudinally and transversely, are assembled from precast, match-cast concrete segments. On the pylons’ tops, anchor containers of the cables had been related to the legs. The tensile drive from the cables is transmitted to the tip metal anchor blocks anchored within the footing slabs.

On the abutments the deck is supported by multi-directional bearings; the longitudinal steering of enlargement actions is ensured by information bearings situated within the bridge axis. To cut back the deck’s longitudinal motion because of the reside load and dynamic part of the wind load, the deck is related with the abutments by 2×2 shock-transition items. These items, along with the mounted connection of the suspension cables with the deck on the mid-span assure the bridge’s aerodynamic stability.

A easy railing, which is fashioned by a handrail supported by inclined posts, has rope filling. The walkway is lit by LED lights located within the handrails.

Using the suspension structural system allowed the designing of a slender and clear construction whose scale corresponds to the setting and whose form matches the attractive countryside the place there isn’t any straight line. The construction is mild and clear; it consists of parts which have a human scale. The construction doesn’t overcome the attractive environment, but it surely enhances them. The bridge is snug for the customers, and its motion attributable to strolling folks or wind doesn’t trigger disagreeable emotions to customers.
