Failed in 1888 with introduction of steel. Site shown on first edition OS map immediately N of bridge; by late C20 completely cleared and redeveloped. On this map called Castle Coch Bridge. Style of masonry comparable to railway bridges of c 1860. The bridge provided important access to the main N/S thoroughfare on the E bank of the River Taff.
