Baker forces Parry at gunpoint to drive to Irene's place on Telegraph Hill to confront her. Instead, Parry drives through the Presidio and heads for an isolated spot under the Golden Gate Bridge. Baker, not the sharpest knife in the drawer, doesn't seem to notice ...
Then ... They are on McDowell Avenue passing under the section of Highway 101 that traverses the Presidio the red marker on this map). Is that a chimney stack in front of the building behind them?
... in 2003 ... the junction looked very similar as recently as 2003 except for changes to the base of the highway pillars but the building and the stack, if that's what it was. are no longer there.
... and Now, In this recent photo we see great change as a new section of Highway 101 takes shape. The old freeway on the left is slated to be removed.
Then ... Next they turn from Long Avenue into Marine Drive about to head up the hill to Lincoln Boulevard.
... and Now , the double-gabled building is still there.
... and Now
Then ... Finally Parry turns onto a service road alongside the bridge.
... and Now , the recent bridge view shows the service road running alongside the bridge to a bluff overlooking Fort Point (map).
They stop at that bluff and Parry manages to grab the gun. The classic shot, below, with the young Golden Gate Bridge as background (it was only 11 years old at that time) anticipated by a decade Alfred Hitchcock's use of the same location in Vertigo.
Then ... A struggle ensues and Parry holds himself back as Baker falls over the edge to his demise.
... and Now , the rocky bluff as viewed from the parking lot at Fort Point.
... on location ... Camera crew and hangers-on posed for this impromptu snapshot atop the bluff where Parry and Baker had their climactic struggle.
