For the property law term, see abutter.
An abutment is an end support of a bridge superstructure. Abutments are used for the following purposes:
- to transmit the reaction of superstructure to the foundations.
- to retain the earth filling.
- to connect the superstructure to the approach roads.
An abutment is also, generally, the point where two structures or objects meet.
Specifically, an abutment may be:
- the part of a structure that supports an arch.
- the tooth or teeth that support a fixed or removable bridge. It can be used between an implant and the crown.
Abutment is also a term used by civil engineers in dam construction; moving water from a large reservoir to a channel such as a spillway, there are smooth transition walls at both sides named abutments which minimize the water's energy loss.
