The bridge led to the main entrance of the Academy and appeared to be heavily fortified with turrets. However, the Locust might have placed them there. A large part of the bridge was destroyed by Reavers storming the Academy.
The Labs were the section of the Academy in which professors and cadets tested new equipment. It was also a JACK bot workshop. In here, Professor Elliot and many of his colleagues designed new equipment and weapons for the COG. Most of the labs and the scientists working there were destroyed when the Locust attacked the Academy.
