There are plans to extend the expressway all the way to I-15. The road east of Mission Road may be rerouted onto a new alignment.
The city of Oceanside does have plans for grade-separated interchanges with College Boulevard and Melrose Drive, should the expressway through Oceanside need to be converted to a freeway.[11]
State Route 76 in Oceanside is an expressway. In March 2009, a new 1.3 mile realigned segment of State Route 76 opened east of I-15. Initially, only two lanes are open, with the other two lanes of this new four lane divided highway planned to open in September 2009. The purpose of this improvement is to reduce accidents on a stretch of road that now carries over 12,000 motorists per day. Much of this traffic is destined for either the Pala Indian casino or a new gravel quarry that was recently opened. The casino and quarry owners each paid for half of the new road. At this time, there are no plans to extend this improvement eastward to Pala. [12]
