This is the junction of Route 1 (Marine Corps Drive) and Route 8.
Some maps refer to this as Leary Junction, while other maps say that Leary Junction connects Route 1 and Route 4 (not Route 8), what we now call the Agana Loop by Chief Quipuha's statue.
The first picture was taken in the early 1970s. We can still see Town House, one of the island's top shopping destinations at the time. The new Ada building is already built, on the left. The Pacific Daily News Building (today the DNA Building) is not yet built.
Marine Corps Drive (called simply Marine Drive in those days) had no median strip and was just 4 lanes wide. There were as yet no sidewalks.
Before the war, this area was known as San Antonio.
