Transforming Hayden Library

Renovation construction reaches the finish line

The vision for Hayden Library has finally taken shape. Construction on the library renovation, along with the revitalization of the Building 14 courtyard, concluded in early spring, and the transformation is remarkable. While access to library buildings has been significantly limited due to the pandemic, we anticipate opening Hayden to the community in the fall and are planning a celebration later in 2021 or when public health guidelines allow. 

In a few months, the final piece will be in place—the community members who will bring these spaces to life as they learn, recharge, and create new knowledge. Until then, Bibliotech takes a closer look at what went into the library and courtyard renovations.
