The eastbound Wilshire Boulevard on-ramp to northbound 405 Freeway will close for 90 days starting Thursday, Aug 22. Once rebuilt, the on-ramp will have nearly 300 percent greater capacity.
It is the last extended ramp closure that will be required for the Wilshire Interchange, as well as the last of its kind for the entire freeway improvements project.
Motorists who normally utilize this on-ramp to access the northbound I-405 from eastbound Wilshire are encouraged to plan ahead to determine alternate routes, allow extra time to reach destinations, eliminate unnecessary trips to avoid peak congestion and/or consider ridesharing and public transit options.
The extended duration closure is required for the contractor to demolish the existing on-ramp and build a new, significantly longer freeway on-ramp that, when complete, will have nearly 300 percent greater capacity than the current freeway ramp.
The new ramp will be 3,129 feet long compared with the current ramp at 824 feet, and is expected to allow far more vehicles to queue on the ramp rather than Wilshire and Sepulveda Boulevards. The ramp will be opened to be public as soon as it is complete.
The on-ramp averages 8,000 vehicles per day, according to the California Department of Transportation (Caltrans).
