KS44 is one side of a road or rail bridge that can span two lines or a road. The bridge side is made up of three pieces, the main arch ( spandrel ) and two buttresses. Then there are two wing walls. These come cut at 90° but you can trim them to have angle walls, see pictures for example, fist picture has the wing wall at 90°.

There is an additional kit you can add which has the wing walls with the opposite angle and walls and buttresses to run the fall length along the top. KS44-01A

We have added additional strengthening corners to the base of the wings.
