A roughly six-mile temporary lane on Interstate 10 between Banning and Cabazon, erected as part of a road work project, will switch this week from the eastbound to westbound side of the interstate.
The crossover lane switch is expected Monday or Tuesday, weather permitting, according to Caltrans spokeswoman Emily Leinen. She noted that wet weather is in the forecast for the Banning Pass Monday, which could push the switch to later this week.
Like its eastbound counterpart, the westbound thoroughfare between Eighth Street in Banning and Main Street in Cabazon will deliver motorists to the opposing side of the roadway via a separated single lane with no shoulder space.
Caltrans said the mechanism is used in order to avoid daytime lane closures. The eastbound lane is already closed to motorists.
Over the past year, crews have been gradually making improvements to nearly 20 miles of freeway between Beaumont and state Route 111 north of Palm Springs as part of the I-10 Pavement Rehabilitation Project, also called the I-10 Tune-Up.
Caltrans advised motorists traveling east or west on the I-10 along the project route to be prepared for lane closures through Thursday between 7 p.m. and 6:30 a.m.
In both directions, lane closures are expected between the SR-111 interchange and Main Street in Cabazon. Crews resumed paving and grading operations in the westbound direction, and roadway excavation going eastbound.
Crews will also be working eastbound between Eighth Street in Banning and Main Street in Cabazon at night doing restriping and other work associated with the shifted crossover lane.
Additionally, the eastbound I-10 connector to SR-111 will be closed intermittently, Caltrans officials said.
No daytime lane closures are currently planned, although crews are set to work through Friday during the daytime hours at various points along the thoroughfare.
The I-10 Tune-Up includes replacing guardrails, repaving outside lanes, replacing slabs in inside lanes and upgrading various on- and off-ramps to comply with the Americans with Disabilities Act.
The $210 million project is primarily funded by the state gas tax, and the remainder through federal funds as well as some funding from the state, according to Caltrans.
Work is scheduled to be completed by the end of 2022.
