tubes Bridge

Proposal for scenic crossing of the Ayalon River

To enrich the experience of crossing the Ayalon and to shorten the length of the bridge required, an Island is proposed in center of the Wadi which separates the flood plane from the river channel. Thus, the main traffic from the parking lot to the mountain, is divided into three sections, "experiences" - a movement through the biodiversity area, crossing the flood plane at ground level, climbing the "Island" hill, crossing the bridge to reach  a rest place and finally climbing the foot terrace and on to Hiriya mountain. The trip Obtained offers a rich experience on ground level, a choreography of movement, a staging of views and plenty of diverse places.

In the Center of the trip to and from Hiriya stands the bridge: an attraction concealed by the "island" hil and hiriyas foot terrace. A place of discovery, fun and entertainment. Inspired by the Baibars bridge, a bridge on the Ayalon near Lod dated from 1273, a bridge length of 35 meters and width required for pedestrians, cyclists and Shuttles is propossed.

Like the Baibars bridge, the bridge proposed is modest and gravitational dimensions, in human proportions. The bridge is built as a seemingly random pile of concrete pipes of different sizes. Recalling recycling of culvert pipes.

Under and on the bridge crossing airy roofed and shade spaces are made: places to stay, play, rest and hide. The use of concrete cylinders recalls the Futurist architect, Yona Friedman, proposal for recycling "Yuval - Gat" factory concrete pipes, meant for the National Water Carrier of Israel, and the touching film "Tzotzsi" by Gavin Hood about a bunch of south African street children.

The bridge offers a variety of movement options. The main traffic on the bridge for pedestrians bicycles and Shuttles. a passage across the river, Under the bridge through the concrete tubes. Ayalon trails passing through the tubes and through the inner space formed between the two sides of the bridge width.

A rest point is planned at southern end of the bridge offering a break for those going up and down the mountain. The rest point contains a roofed pipe space, a big tree and a sebil- a public drinking fountain.

The bridge is built of concrete pipes and beam of variable diameter. The Upper surface level is obtained with a soil fill that allows growth of vegetation. Balustrade is proposed by closing the tubes ends with rings nets.
Applicants of this proposal Doubt the need to build a 160 meters long bridge floating above the ground.  The effort and investment needed to erect such a bridge, only for the rare floods once 100 or even 25 years, is not ecological, not economic, and obstructive to the landscape. In the case of flood Hiriya mountain can be reached via alternative roads.

The experience of traveling on a 160 meter floating bridge produces an experience of detachment and alienation. Such linear movement though ceremonial undiversified. However, the proposed trip is one of diverse experiences, discovery and motion on the ground' encounter with terrain and nature and with the Ayalon river. A 160 m bridge is necessarily present as an object in the landscape competing with the presence of the mountain, dwarfing the width of the Ayalon valley. The easy above transition dims the presence of the Ayalon River and the crossing experience. In contrast to a long big structure the proposed bridge ecological footprint is relatively small.


The meeting with the bridge is conceived as surprising, inviting a smile, play and stay.
