SkyWay: high evenness of the track

High evenness of the track is achieved due to the uncut structure of string rail between anchor supports.

Advantages of SkyWay:

• intermediate supports installed at a span from 25 up to 100 metres (to ensure rigidity of the uncut track structure) allow to use light structures;
• fixing of the support top to the track structure allows to additionally increase its load-bearing capacity by 8 times;
• the amount of materials required for installation of supports can be reduced by 8 times, resulting in cost reduction by the same figure.

Uncut structure of the string rail in its overpass design, compared to a conventional beam overpass, reduces the amount of building materials by 15 times and more.

Construction cost of a conventional overpass with ordinary supports - from 100 mln USD/km, construction cost of SkyWay overpass - from 3 mln USD/km.
