Luis Rey River. Concerns arose that the TransNet local sales tax would not be extended by voters, leading to the cancellation of that project. The San Diego Association of Governments included the widening east to Bonsall in the regional plan in 2003, but indicated that the portion from Bonsall to I-15 would be dependent on the availability of funding. Residents of Fallbrook and Bonsall criticized the fact that SR 76 was one of the few TransNet projects that was not to be completed by the expiration of the tax in 2008. The city of Oceanside proposed plans for grade-separated interchanges with College Boulevard and Melrose Drive in 2004, as part of a proposal to convert the expressway through Oceanside to a freeway. After complaints from residents, these proposals were tabled. After TransNet was renewed in November 2004, planning continued for widening the remaining portion of SR 76 west of I-15, due to the frequent accidents that occurred on the eastern portion, although some claimed that the habits of drivers were at fault. The 2007 environmental impact report recommended constructing the new roadway along the route of the old one, rather than moving the entire highway south. Meanwhile, congestion east of I-15 increased with the opening of four new casinos near Pala. The Pala Indian band was required to pay for the costs to improve the road to mitigate the increased traffic levels from their proposed expansion. Construction began on widening the highway in April 2008, and in March 2009, two lanes of a realigned segment of SR 76 opened east of I-15. Initially, only two lanes were open, with the other two lanes of this new four-lane divided highway planned to open in September 2009. This improvement was intended to reduce accidents on a stretch of road that carried over 12,000 motorists per day, many headed for either the Pala Indian casino or a new gravel quarry that had recently opened. The casino and quarry owners each paid for half of the $26 million (about $ in dollars) cost of the new road. Even after this, in 2009, the corner of SR 76 and Palomar Mountain Road was determined to be the place in the county with the most motorcycle accidents. Construction started on widening SR 76 between Melrose Drive and South Mission Road in January 2010 to four lanes, funded by the federal and state governments and by TransNet
