      abstract     = {The Large Hadron electron Collider (LHeC) is the proposal
                      to deliver electron-proton/nucleus collisions at CERN using
                      the LHC hadron or nuclear beams and a 50 GeV electron beam
                      from an Energy Recovery Linac (ERL) in racetrack
                      configuration. While the 2021 update of its CDR [1]
                      contemplated concurrent operation of electron-hadron and
                      hadron-hadron collisions at the HL-LHC followed by
                      standalone electron-hadron collisions, we propose, in view
                      of the current HL-LHC schedule, an LHeC program extending
                      the regular HL-LHC program with only a standalone
                      electron-hadron operation phase [2]. In this way, the LHeC
                      becomes a bridge from the HL-LHC to the next flagship
                      project at CERN.In this talk we review the EW and top
                      physics studies at the LHeC. We present new results on the
                      extraction of the Weinberg angle and top, Z and W masses,
                      together with the impact of the improved determination of
                      PDFs+ at the LHeC on their extraction at the HL-LHC. We also
                      present the possibilities for the determination of neutral
                      current vector and axial couplings to light quarks, and for
                      constraining parameters in SMEFT analyses. Concerning top
                      physics, we present the determination of and and of
                      anomalous couplings, including FCNC and, and of magnetic and
                      electric dipole moments.[1] P. Agostini et al. (LHeC/FCC-he
