In 'Road Pirates' Bo and Luke visit Colonial City, however the loading bay is actually at the back of the church on Hazzard Square (marked #17 on the map). There is a wider view above in the post relating to 'Route 7-11'. The building in the background of the first picture is the same building that is in the background of the 'Road Closed' shot above. This loading bay gets used in a couple of other episodes that I'll show in the future.
Now, from 'The Ghost of General Lee', another example of strange continuity when you know the layout of the square. I've set it like a storyboard to demonstrate:
A. General Lee leaves the impound garage, now located in building #31 (that's buildings #1 and #2 opposite).
B. As it exits it crashes into Rosco's car as if they've just left Cooter's (#22).
C. Rosco hits a fire hydrant outside building #31
D. (A little later in the chase) A car reverses out from the impound garage.
E. Rosco has to swerve to avoid the reversing car (note that the fire hydrant has gone, but the road is still wet from the previous stunt).
F. Rosco crashes through the doors of the impound garage.
G. Rosco exits the impound garage by crashing through the same doors (shot from a different angle and framed differently).
H. Rosco crashes into the furniture store (#10) as if he was coming from the direction of the church.
