the southbound lanes of interstate 5 which take vehicles into mexico have been moved west of their previous location through the new el chaparral point of entry (). this relocation and expansion was necessary to provide space for the construction of new administrative and border inspection facilities and to increase the number of northbound vehicle lanes. the el chaparral gateway also has a vehicle and passenger inspection station at which u.s. officials may conduct inspections of southbound traffic, and provides for more thorough inspection of southbound traffic by mexican officials. el chaparral was the name of the tijuana border crossing prior to the 1983 modifications.
