Construction is beginning two decades after the state was first ordered to provide female inmates the same services as their male counterparts.
The new prison will be behind the state prison for men in Concord. It will have four buildings and include facilities for health services, programming and education, visitation, industries and housing.
There will be two stand-alone general population housing units and one minimum security housing unit. One of the general housing units will provide services for inmates with mental health and substance abuse needs.
The prison is estimated to cost $38 million and construction is expected to take two years.
