During 2007, RCTC will begin the environmental clearance process to add as many as three lanes in each direction on State Route 91.  The improvements will include:

• One general purpose lane in each direction to be funded by Riverside County's Measure A, half-cent sales tax program
• A direct flyover connector between the eastbound State Route 91 and northbound State Route 71
• The addition of collector/distributor road systems near the I-15 and Main Street and Corona and the area between State Route 71 and Serfas Club Drive
• The development of two high occupancy toll lanes in each direction (similar to the 91 Express Lanes) between Orange County and I-15 which will also include an improved direct connection from I-15
• Auxiliary lanes to assist with access and merging on throughout State Route 91

Together, RCTC and OCTA will proceed with environmental and preliminary design work and seek sources of funding for the following projects:

• Construct a new eastbound lane between the Foothill/Eastern Toll Road (SR-241) and the Chino Valley Freeway (SR-71). OCTA authorized the use of $2.5 million dollars in Express Lanes toll revenue as seed funding to accelerate preliminary engineering and environmental documentation to get this project moving. When completed this $75 million project will open up a major eastbound traffic chokepoint at the Orange County / Riverside County line. Project completion is anticipated for 2011.
• Add new lanes in each direction on SR-91 between the Corona Freeway (I-15) and the Foothill/Eastern Toll Road (SR-241). Project completion is scheduled for 2015.
• Evaluate a seven-mile reversible lane facility on SR-91 between Orange County / Riverside County line to I-15. Project details are under development.
• Evaluate a new freeway interchange at Fairmont Boulevard connecting to and from the north side of SR-91. Project details are under development.
• Add a fifth general purpose lane in each direction between the Costa Mesa Freeway (SR-55) and SR-241. Conceptual engineering is complete and a future environmental document will refine project details.
• Build a new direct connector between the 91 Express Lanes and SR-241 toll road. Project details are under development.
• Construct a new direct carpool-lane connector between SR-91 and I-15. Project details are under development. 
• Caltrans and RCTC are about to embark on a $26 million project to reconstruct the State Route 91/Green River interchange. The scope includes the widening of the bridge over the freeway and enhance on and off-ramps. Construction is expected to begin in March 2007. Click here for more information. 
• Provide free tow services through the Freeway Service Patrol program during peak AM and PM commute hours to commuters traveling on the SR-91.  This service helps stranded motorists get quickly back on the road and clears incidents or debris to maximize traffic flow and highway safety.
