1) Archaic form of 'rampart'.
These archaic forms of ‘rampart’ appear to have two distinct meanings in connection with bridges. In the first, the word was used of a reinforced river embankment, and there is a descriptive reference in the repairs to Kettlewell Bridge: 1686 the rampier on the south end to extend 20 yards in length up the water and to be carried 12 yards in length below the bridge
and that on the north end to bee 12 yards in length on each side. The rampire may originally have been the earth embankment itself but in such cases it was clearly the wing or wing wall of the bridge. A reference to the old ramper wall of Hampsthwaite Bridge, in 1717 may represent a transitional stage in the word’s semantic development. The second meaning occurs when ‘rampire’ is used as a synonym of causey, as it is several times from 1687, e.g. with a Ramper or Cawsey … from the foot of the bridge 67 yards in length. Here also the rampire must initially have described the raised earthwork.
