071411 _ TRAN 405 freeway logoAs part of its continuing work to improve the Wilshire/Interstate-405 Interchange, Metro and Caltrans plan to close the southbound I-405 off-ramp to westbound Wilshire Boulevard for two weeks beginning at 8 p.m. Friday, March 8.

The new ramp is scheduled to open by 6 a.m. Friday, March 22.

Metro and Caltrans advise motorists to plan ahead, adjust their travel times, or share the ride during this time to reduce traffic impacts.

The ramp closure is necessary to demolish the existing off-ramp, rebuild it, conduct roadway paving and shift K-rails. This is the third ramp to be demolished and rebuilt to date as part of the eight-ramp Wilshire interchange improvement work, officials said.

The detour route is as follows: Santa Monica Boulevard exit eastbound to Sepulveda Boulevard to Wilshire Boulevard. A detour route map is available on www.metro.net/projects/I-405/segment-detours.

Changeable message signs will be used, and traffic control officers will be deployed to help direct drivers and mitigate traffic impacts.

Once built, the reconstructed Wilshire interchanges will produce some of the I-405 project’s greatest local traffic improvements, officials said. By building new, seismically updated and higher capacity ramps, the project will reduce the vehicular conflicts between Wilshire Boulevard and the I-405. Officials said this should reduce backup at other north/south streets, and bring capacity to meet expected vehicle demands in 2031.
