    100 College Street Medical Lab

    Construction started on 100 College in June 2013 and when complete it will be the first building developed as part of the City’s Downtown Crossing project, which will replace a limited access highway stub that cuts through downtown with a pair of urban boulevards. 100 College is being built in the former highway right-of-way in order to take full advantage of its proximity to Yale - New Haven Hospital and the Yale School of Medicine.

    Alexion Pharmaceuticals will be 100 College Street’s first tenant occupying 300,000 square feet of the 425,000 sq. ft. building, with 300 employees initially, but with plans to add 300 more over the next five years. Alexion has a market cap of $19.21 billion and operations in 30 countries, and is an industry leader in developing treatments for rare diseases.

    · Medical / Lab Space: 425,000sf

    · Construction Jobs: 2,000

    · Permanent Jobs: 960

    · Project Cost: $140 million
