On November 8, when Lawson was briefed on the itinerary for the trip to Dallas, he was told that 45 minutes had been allotted for a motorcade procession from Love Field to the luncheon site. Lawson was not specifically instructed to select the parade route, but he understood that this was one of his functions. Even before the Trade Mart had been definitely selected, Lawson and Sorrels began to consider the best motorcade route from Love Field to the Trade Mart. On November 14, Lawson and Sorrels attended a meeting at Love Field and on their return to Dallas drove over the route which Sorrels believed best suited for the proposed motorcade. This route, eventually selected for the motorcade from the airport to the Trade Mart, measured 10 miles and could be driven easily within the allotted 45 minutes. From Love Field the route passed through a portion of suburban Dallas, through the downtown area along Main Street and then to the Trade Mart via Stemmons Freeway. For the President's return to Love Field following the luncheon, the agents selected the most direct route, which was approximately 4 miles.
After the selection of the Trade Mart as the luncheon site, Lawson and Sorrels met with Dallas Chief of Police Jesse E. Curry, Assistant Chief Charles Batchelor, Deputy Chief N. T. Fisher, and several other command officers to discuss details of the motorcade and possible routes. The route was further reviewed by Lawson and Sorrels with Assistant Chief Batchelor and members of the local host committee on November 15. The police officials agreed that the route recommended by Sorrels was the proper one and did not express a belief that any other route might be better. On November 18, Sorrels and Lawson drove over the selected route with Batchelor and other police officers, verifying that it could be traversed within 45 minutes. Representatives of the local host committee and the White House staff were advised by the Secret Service of the actual route on the afternoon of November 18.
The route impressed the agents as a natural and desirable one. Sorrels, who had participated in Presidential protection assignments in Dallas since a visit by President Franklin D. Roosevelt in 1936,as testified that the traditional parade route in Dallas was along Main Street, since the tall buildings along the street gave more people an opportunity to participate. The route chosen from the airport to Main Street was the normal one, except where Harwood Street was selected as the means of access to Main Street in preference to a short stretch of the Central Expressway, which presented a minor safety hazard and could not accommodate spectators as conveniently as Harwood Street. According to Lawson, the chosen route seemed to be the best.
It afforded us wide strees most of the way, because of the buses that were in the motorcade. It afforded us a chance to have alternative routes if something happened on the motorcade route. It was the type of suburban area a good part of the way where the crowds would be able to be controlled for a great distance, and we figured that the largest crowds would be downtown, which they were, and that the wide streets that we would use downtown would be of sufficient width to keep the public out of our way.
Elm Street, parallel to Main Street and one block north, was not used for the main portion of the downtown part of the motorcade because Main Street offered better vantage points for spectators.
To reach the Trade Mart from Main Street the agents decided to use the Stemmons Freeway (Route No. 77), the most direct route. The only practical way for westbound traffic on Main Street to reach the northbound lanes of the Stemmons Freeway is via Elm Street, which Route No. 77 traffic is instructed to follow in this part of the city. Elm Street was to be reached from Main by turning right at Houston, going one block north and then turning left onto Elm. On this last portion of the journey, only 5 minutes from the Trade Mart, the President's motorcade would pass the Texas School Book Depository Building on the northwest corner of Houston and Elm Streets. . . .
The Elm Street approach to the Stemmons Freeway is necessary in order to avoid the traffic hazards which would otherwise exist if right turns were permitted from both Main and Elm into the freeway. To create this traffic pattern, a concrete barrier between Main and Elm Streets presents an obstacle to a right turn from Main across Elm to the access road to Stemmons Freeway and the Dallas-Fort Worth Turnpike. This concrete barrier extends far enough beyond the access road to make it impracticable for vehicles to turn right from Main directly to the access road. A sign located on this barrier instructs Main Street traffic not to make any turns. In conformity with these arrangements, traffic proceeding west on Main is directed to turn right at Houston in order to reach the Dallas-Fort Worth Turnpike, which has the same access road from Elm Street as does the Stemmons Freeway.
