 A new port of entry facility was built, and the SENTRI lane opened in September 1999.Next, the SENTRI team elected to deploy a system at the busiest single border crossing in the world, San Ysidro, California.The congested nature of Tijuana, near the border crossing, made it difficult to identify a place to put the dedicated lane, but with the cooperation of many organizations on both sides of the border, a lane was segregated, and SENTRI opened at San Ysidro in 2000, after which point the SENTRI team was disbanded, and SENTRI became a program office within INS.
