The factors involved in the choice of the motorcade route by the Secret Service have been discussed in chapter II of this report.[C6-2] It was there indicated that after passing through a portion of suburban Dallas, the motorcade was to travel west on Main Street, and then to the Trade Mart by way of the Stemmons Freeway, the most direct route from that point. This route would take the motorcade along the traditional parade route through downtown Dallas; it allowed the maximum number of persons to observe the President; and it enabled the motorcade to cover the distance from Love Field to the Trade Mart in the 45 minutes allocated by members of the White House staff planning the President’s schedule in Dallas. No member of the Secret Service, the Dallas Police Department, or the local host committee who was consulted felt that any other route would be preferable. To reach Stemmons Freeway from Main Street, it was determined that the motorcade would turn right from Main Street onto Houston Street for one block and then left onto Elm Street, proceeding through the Triple Underpass to the Stemmons Freeway access road. This route took the motorcade past the Texas School Book Depository Building on the northwest corner of Elm and Houston Streets. Because of the sharp turn at this corner, the motorcade also reduced its speed. The motorcade would have passed approximately 90 yards further from the Depository Building and made no turn near the building if it had attempted to reach the Stemmons Freeway directly from Main Street. The road plan in Dealey Plaza, however, is designed to prevent such a turn. In order to keep motorists from reaching the freeway from Main Street, a concrete barrier has been erected between Main and Elm Streets extending beyond the freeway entrance. (See Commission Exhibits Nos. 2114-2116, pp. 35-37.) Hence, it would have been necessary for the motorcade either to have driven over this barrier or to have made a sharp =S=-turn in order to have entered the freeway from Main Street. Selection of the motorcade route was thus entirely appropriate and based on such legitimate considerations as the origin and destination of the motorcade, the desired opportunity for the President to greet large numbers of people, and normal patterns of traffic.
