Construction will begin this week to expand California’s busiest border crossing point with Mexico for commercial trucks. The General Services Administration will embark on a $37.2 million modernization effort to expand processing capacity for trucks and pedestrians moving between San Diego and Tijuana at the Otay Mesa crossing station, located along state Route 905. The project includes an expanded northbound commercial truck inspection facility that will increase the number of inspection booths from 10 to 16. The Otay Mesa facility cleared nearly 950,000 trucks in 2019, according to the Bureau of Transportation Statistics.
