The SPD project for spin physics studies at the NICA accelerator complex

The status of the Spin Physics Detector (SPD) project at the NICA accelerator complex now under construction in the JINR, Dubna is given. The expected availability of high luminosity colliding beams of polarized protons and deuterons opens wide opportunities for nucleon spin physics studies. Possible measurements are discussed together with a concept for general purpose detector to study the interactions of polarized particles in collider mode. Anticipated detector design and status of the Conceptual Design Report being prepared is given.
