The chase scene starts at 1h:05m into the film. The total time of the scene is 10 minutes and 53 seconds, beginning in the Fisherman's Wharf area of San Francisco, at Columbus and Chestnut (although Bullitt first notices the hitmen following his car while driving west on Army Street, now Cesar Chavez Street, just after passing under Highway 101), followed by Midtown shooting on Hyde and Laguna streets, with shots of Coit Tower and locations around and on Filbert and University streets. The scene ends outside the city at the Guadalupe Canyon Parkway in San Bruno Mountain near Brisbane. The route has been mapped, showing that it is geographically impossible to take place in real time.
