to explore ways to pay off the debt. SR 11 / SR 905 interchange Before being upgraded to a freeway between Britannia Boulevard and Siempre Viva Road, SR 905 directly connected with SR 125 via two at-grade intersections on Otay Mesa Road. When Caltrans opened that segment of the SR 905 freeway in 2010, they omitted the interchange with SR 125, forcing traffic on SR 905 and SR 125 to exit their respective freeways and use Otay Mesa Road (which SR 905 followed at that time) to make the connection. To help fix this problem, a direct freeway-to-freeway interchange was planned, which also included the new SR 11 freeway once it was to be constructed, with construction beginning in late 2015. SR 11 is planned to be a toll facility that will serve a new border crossing east of Otay Mesa. Ramps from SR 905 eastbound to SR 125 northbound, SR 905 westbound to SR 125 northbound, and SR 11 westbound to SR 125 northbound were completed on November 30, 2016, at the cost of over $21 million. Prior to December 16, 2021, traffic on southbound SR 125 was forced to exit onto Otay Mesa Road at that toll road's then southern terminus in order to connect to SR 11 and SR 905. Construction on the ramps for these connections began in 2018, with the ramps from SR 125 southbound to SR 11 eastbound and SR 125 southbound to SR 905 eastbound being completed on December 16, 2021, at the cost of $74 million. The ramp from SR 125 southbound to SR 905 westbound, which was still under construction at the time, was initially scheduled to open to traffic in 2023, but was instead opened to traffic on July 26, 2022, finally completing the interchange. There are no plans to construct the remaining connections from SR 905 westbound to SR 11 eastbound and SR 11 westbound to SR 905 eastbound. Tolls Tolls along the South Bay Expressway depend on whether a driver uses the FasTrak electronic toll collection system or pays by cash or credit card. Those using the FasTrak transponder pass under open road tolling gantries at all exits and entrances and are charged a prorated toll based on the distance traveled, similar to a toll ticket system used on several turnpikes in the Eastern United States. Drivers paying with cash or credit cards are instead charged a more
