threaded hole 180 a second threaded hole 182 and a third threaded hole 184 the threaded holes on the pile cap 112 are spaced to match the spacing of the lifting rods spaced across the support bar 148 the releasable connection between the threaded holes and the lifting rods is made by mating the threads of the lifting rods with the appropriate threaded hole of the pile cap 112 the load bearing surface 186 is adapted to support new pre cast concrete bridge spans which in turn support the existing elevated rail assembly the pile cap 112 can further include three additional threaded holes located between the center threaded hole 176 and the inboard threaded hole 174 so that the pile cap 112 is symmetrical about the center past attempts of providing the lifting points or threaded holes in the pile cap 112 involved welding threaded steel nuts to reinforcing steel that was then cast in the material of the cap it has been found that the heavy load of the pile cap striped the threads of the welded nuts thus as best shown in fig2 b the threaded holes 174 176 178 180 182 and 184 according to the present invention are preferably formed from cut lengths of oil well drilling pipe 190 the pipes 190 are attached to reinforcing steel 188 and then cast into the concrete when the cap 112 is formed the oil well drilling pipe 190 is internally threaded and is flush with the load bearing surface 186 of the cap 112 the flush ends of the pipe 190 will not interfere with the new pre cast concrete spans to be supported on the load bearing surface 186 the threaded holes 174 176 178 180 182 and 184 are tapered to provide automatic.
