Halawa is also the site of Aloha Stadium which is home to the University of Hawaii Warriors football team and many other sporting events. On the ocean side of Halawa is Pearl Harbor. Halawa Valley becomes wider near Pearl Harbor and this is where most of the residential neighborhoods are located.
Halawa Valley has many important cultural sites dating to ancient times. This led to many protests during the building of the H-3 Freeway which opened in 1997 running right through the valley.
