Seawolf Advisory!

This morning, our Facilities and Campus Services team was made aware of a pothole that shut down the westbound lanes of Northern Lights Boulevard between UAA Drive and Career Center Drive. It has since been upgraded to a sinkhole, and the lanes will remain closed for an undetermined amount of time while crews repair the damage. We anticipate the closure will extend through the week.

Finals week is a very stressful time for students. Students, please know that your professors have been made aware of the situation. Please communicate with them any delays you may experience due to this issue. We know this is an unexpected traffic challenge. Please take a deep breath. We want you to have a smooth and safe finals week.
