Crews will close the off-ramp from southbound I-405 to northbound State Route 167 at 9 p.m. today (Monday) to repair a concrete barrier and attenuator damaged earlier from a collision.

Crews need to straighten the concrete barrier and replace the attenuator. The closure should take about an hour. A detour route will be posted.

It’s the same barrier that was damaged in an accident about two weeks ago; the off-ramp was closed then, too.
