Wilshire Bl Ramps Reconstruction


On Friday, June 22, 2012, the I-405 Sepulveda Pass Improvements Project will begin demolishing the first of eight ramps joining Wilshire Bl and the I-405 freeway. This rebuilding begins with the demolition of two ramps:

  • I-405 N off-ramp to Westbound Wilshire
  • Westbound Wilshire on-ramp to I-405 N

The contractor anticipates rebuilding these two ramps in 90 days. Reconstruction of all eight Wilshire ramps is expected to take more than one year.

These closures and the subsequent reconstruction of the other six Wilshire ramps are expected to create significant temporary impacts to Wilshire Bl and adjoining streets, such as Federal Av, Sepulveda Bl and Veteran Av. Sunset Bl and Santa Monica are recommended alternatives.

Building the new ramps will reduce the conflict between Wilshire Bl and the I-405 as it crosses Wilshire Bl. In turn, this should reduce backup at other north/south streets, such as Westwood Bl and Veteran Bl.

In addition to addressing problems afflicting one of California’s busiest interchanges, reconstruction of the Wilshire ramps will upgrade them to the latest seismic standards.

The current off-ramp/on-ramp configuration presents a dangerous situation at these of these regionally important intersections:

  • Westbound Wilshire Bl on-ramp to the southbound I-405
  • Southbound I-405 off-ramp to eastbound Wilshire Bl
  • Northbound I-405 off-ramp to westbound Wilshire Bl
  • Eastbound Wilshire Bl on-ramp to northbound I-405

At these locations, a mass of drivers struggle to reach a through-freeway lane or change lanes to reach the off-ramp exit. These maneuvers must occur within a short distance and feature the same chaos: the on-ramp traffic slows to merge on while off-ramp traffic speeds up to merge off.

The reconstruction of the Wilshire Bl ramps and their connections with the I-405 freeway require a complex construction schedule to minimize the traffic effects at these heavily traveled interchanges. Although the reconstructed interchanges will produce some of the I-405 project's greatest traffic improvements, the multiple ramp closures will affect traffic flow for miles.
