AbutmentA retaining wall supporting the ends of a bridge or viaduct.Pierssupport if continuous bridge
There is no great difference between between the two in principlebut,In a Carey foster's bridge there is no end resistance whereas in the case of a metre bridge end resistance afffects our readings.Hence Carey foster bridge is more accurate than metre bridge .Carey foster bridge can also measure low resistance and high resistance but a metre bridge cannot do so.
