From 9 p.m. Friday, March 13, to 4 a.m. Monday, March 16, crews will close all lanes of northbound I-405 at the SR 522 Interchange and all lanes of southbound I-405 from SR 527 to SR 522 to remove ramp sections over I-405. Signed detours will be in place:Northbound I-405 nighttime detour,Northbound I-405 daytime detour,Southbound I-405 detour.
Travelers should expect 2- to 3- mile backups on I-405 during the full closures. A one-hour delay in both directions is the best-case scenario during peak travel times.This work is part of theI-405/Brickyard to SR 527 Improvement Project.
