SkyWay technology and conventional beam overpass

Split overpass (conventional bridge):

Innovative uncut pre-stressed overpass (SkyWay technology):

Thus, with equally distributed load, SkyWay overpass is 5 times more rigid (smoother) and 3 times stronger than a conventional bridge.

Thus, with equal concentrated force, SkyWay overpass is twice more rigid (smoother) and 1,5 times stronger than a conventional bridge.

Solid roadbed in conventional bridge gives additional load onto supports. 90% of load in a conventional overpass is its own weight:

Only 10% of load in a SkyWay overpass is its own weight:

Thus, SkyWay overpass decreases the amount of building materials and, consequently, reduces the cost by 15 times compared to a conventional overpass.
