RCTC and OCTA developed and annually update a 91 Implementation Plan. The 91 Implementation Plan details a series of projects that promise to provide a faster, more reliable commute between Riverside and Orange counties.
The proposed transportation improvements have the potential to reduce travel time on SR-91 during the next decade, cutting commute times by more than an hour by 2015 for commuters traveling eastbound between the Costa Mesa Freeway (SR-55) in Orange County and the Corona Freeway (I-15) in Riverside County. Currently, eastbound travel times between the SR-55 and the I-15 average nearly 100 minutes in the afternoon peak hour. By 2011, travel times are expected to decrease by approximately 20 minutes, and could decrease by an additional 60 minutes by 2015.
The package of transportation projects is expected to cost more than $9 billion to build. The plan includes a proposed timeline for improving specific segments of SR-91:
2011: Open a new eastbound lane on SR-91 between the Foothill Toll Road (SR-241) and the Chino Valley Freeway (SR-71); make safety improvements to the truck scales near Weir Canyon Road; improve Express Bus and Metrolink commuter-rail service
2015: Add a new lane in each direction on SR-91 between the Corona Freeway (I-15) and the Foothill Toll Road (SR-241); add a seven-mile reversible lane facility on SR-91 from the Orange/Riverside county line to I-15; build a new freeway interchange at Fairmont Boulevard
2020: Add a fifth general purpose lane in each direction between SR-55 and SR-241; also expand Metrolink commuter-rail service
2030: Project concepts beyond 2020 include:
- Building a new direct connector between the 91 Express Lanes and the SR-241 toll road
- Constructing a new direct carpool-lane connector between SR-91 and I-15
- Adding a new four-lane elevated highway between SR-241 and I-15
- Adding a new four-lane highway corridor that could include a tunnel from the SR-241/SR-133 interchange in Orange County to I-15 at Cajalco Road in Corona
Many of the above concepts are still undergoing feasibility studies and do not yet have a well-defined timeline for implementation.
