This probably deserves some updates:
In February 2018, it was reported that RCTC officials still feel that fixes are needed in the Route 91 corridor. An additional westbound freeway lane, from Route 71 Freeway to Route 241, was one solution presented in mid-February 2018 to the Riverside County Transportation Commission. Corona Mayor Karen Spiegel and a few other commission members cited that option as one worth exploring to deal with back-ups on Route 91 and nearby city roads that have left some commuters frustrated. Since the toll lanes opened in March 2017, they’ve been used by 1.2 million vehicles – about 40 percent more than the agency projected – a report to the commission states. That’s 37,893 vehicles on an average day. That figure has resulted in $22.1 million in toll revenue – about $15.5 million more than the agency anticipated. The project has reduced congestion during many times of the day on the heavily-traveled corridor. However, there are some “hot spots” at which motorists continue to face congestion, including the entrance to the toll lanes on westbound Route 91, past McKinley Street, and the northbound I-15 Freeway connector to westbound Route 91 entering the toll lanes. One of the worst is westbound Route 91 from Route 71 going past Green River Road and toward the Orange County line. During the morning commute, 1,800 to 2,000 vehicles an hour are entering the westbound Route 91 from Route 71 and Green River. As a result, Green River – which connects to Route 15 through the Foothill Parkway – has seen vehicles backing up for a mile or two on weekday mornings, residents say. The additional lane – which would be added by converting the existing right-hand shoulder pavement – is one of six options for the Green River corridor. Others included adding the lane for a shorter distance, moving the toll lane entrance and exits further east, converting the toll lane exit and entrance into a continuous weaving lane and turning off the metering ramp at the Green River entrance. For northbound I-15, the two proposed solutions were extending the toll lanes further south and adding a second entrance to the toll lanes.

In May 2018, it was reported that the Riverside County Transportation Commission approved in a near-unanimous vote environmental studies and design work for adding a general-purpose westbound lane on Route 91, stretching from Green River Road to Route 241 in Orange County. The panel intends to reconvene in the fall to decide whether to move forward with construction of the new lane, expected to cost $30 million to $50 million and take two and a half years to build.

In March 2018, it was reported that the CTC awarded $50 million in state funds to launch environmental studies that will set the stage for building tolled express lanes on I-15 between Cajalco Road in Corona and Route 74 in Lake Elsinore, a news release reports. Those studies are expected to take five years to complete. The grant is contingent on the recent state gas-tax increase remaining in place, the news release stated. The project would extend lanes that are under construction now in a 15-mile segment between Cajalco Road and Route 60.

In March 2018, it was reported that the CTC awarded $2.9 million to the I-15/Railroad Canyon Road interchange in Lake Elsinore.

In May 2018, it was reported that the Riverside County Transportation Commission approved in a near-unanimous vote lengthening by one mile the northbound I-15 toll lanes – which begin at Ontario Avenue now – and creating a continuous lane for entering and exiting the Route 91 toll lanes at the Riverside-Orange county line (these would now start around Foothill Parkway).
