The construction of a "dual freeway" at the western end was scheduled to begin in early 2002, referring to the two carriageways needed for each direction of the freeway. It would require drivers to use the new local lanes to access eastbound SR 56 from I-5 or I-805. The project would allow for trucks to use the new lanes to assist in merging with traffic. The northbound lanes were scheduled to open in February 2006. The southbound I-15 to westbound SR 56 ramp was improved in a construction project in 2005.
