Here is a youtube of a part of Wesley Buell Frazier's re-enactment of his drive to his carpark the morning of Fri 22Nov1963.
Here is a pix of Buell's route. His route is colored yellow.
The re-enactment included the bits colored red.
And not shown is that he drove along Commerce St under the triple underpass before he turned left into Record St.
The re-enactment included walking along the bits colored green. It included a shot of the rear entrance on the north east corner of the TSBD.
The big building opposite Frazier's carpark is the 4 story TSBD Co "State" warehouse at 1917 North Houston St. Shields & Given were said to be working there when Frazier parked on that Friday.
MR. BALL -- "What route did you take into town that day [11/22/63]?"
MR. FRAZIER -- "I told you I had two routes...Fifth Street runs into
Sixth after you cross the Storey Road there, so I just went on down
Sixth until I come to O'Connor, and then took a left on O'Connor and
it takes you right on out to Stemmons, and from there I went right on
into Stemmons and come up Commerce; and you go up Commerce there until
you hit Record Street, that is one block over from Houston, and then I
went down until I hit McKinney and then it goes right down to the
warehouse, and then take a left and you go right around to the parking
lot. ....
