© 2021 World Scientific Publishing Company.In this work, we have studied various cosmological parameters in the presence of viscous new Tsallis holographic dark energies for interacting scenarios in the framework of Chern-Simons modified gravity. The bulk viscosity has been considered with the bulk viscous pressure chosen in the form =-3H(ζ0 + ζ1H + ζ2 + H2)). Hubble parameter H has been obtained from the above choice of scale factor and in this viscous scenario, the effective pressure has been obtained in Chern-Simons framework whose field equation, cosmological consequences have been investigated. It has been observed that for the interaction scenario in the presence of bulk viscosity the EoS parameter is staying above-1, which indicates quintessence behavior. Hence, for the universe filled with a bulk viscous fluid can have the possibility of avoidance of big-rip, although the earlier transition from quintessence to phantom is not avoidable.
