Project contractors are planning to close a portion of the northbound I-405 over the Sepulveda Pass starting Saturday night, Sept. 24, for one night to take down some freeway signs and other equipment that are currently in the way of the new traffic lane now being constructed.

Temporary signs indicating how many miles to the next street exit will be put in their place, but the northbound-only side of the freeway will be closed for about five miles between Getty Center Drive and Ventura Boulevard while this work is performed. Another similar closure may be required later. As with all of these types of directional freeway closures, Sepulveda Boulevard will remain open as the official detour route between the closure hours of 1 a.m. to 7 a.m. Sunday morning.

The construction notice is after the jump.
