mid-1974. In January 1976, the part of SR 75 between I-805 and Otay Mesa Road was opened to traffic. On April 6, the next portion of the freeway opened. However, there were concerns about what to call the freeway, citing confusion with the northern portion of SR 75. The entire cost of the project was $6.3 million. SR 117 was extended east to SR 125, replacing the southerly segment of SR 75, by the Legislature in 1976; this took effect at the beginning of 1977. Estimates for completing the freeway ran from $13.8 million to $28.5 million. In late 1977, the CPO made plans to push for adding SR 117 to the Interstate Highway System, to obtain additional federal funding. By 1979, both San Diego city and county had allocated $6 million to construct a temporary way to access the border crossing along Otay Mesa and Harvest Roads. Two years later, the City of San Diego indicated that the upgrade of Otay Mesa Road to a four-lane road would be the preferred option; the state agreed to allocate $2 million towards the $10 million project, with the city contributing $6.4 million and the county adding $2.3 million. The Federal Highway Administration approved the continuous roadway via SR 117 and SR 125 from I-5 to the border at Otay Mesa as a non-chargeable (not eligible for federal Interstate Highway construction dollars) part of the Interstate Highway System in October 1984. The Otay Mesa border crossing opened on January 24, 1985. The route number was legislatively changed to 905 in 1986, and signs were updated in 1988. This change was to apply for other federal funding. The original piece of SR 117, west of I-5, also became SR 905 with the rest of SR 117, but the California Department of Transportation (Caltrans) has not constructed it. Efforts were underway in 1997 to secure federal funding for the highway and other infrastructure near the Mexican border, largely supported by Senator Barbara Boxer and Representative Bob Filner, and Representative Bud Schuster, the chairman of the House Transportation and Infrastructure Committee, visited the region before giving informal approval to the proposal. In 1999, Governor Gray Davis approved allocating $27 million in federal funding to complete the freeway. Concerns were expressed by local residents and municipal officials regarding the apparent priority of SR 125 over SR 905 in terms of funding, especially since SR 125 was
