Two 405 Freeway ramps at Magnolia Street to be closed for a month

Two 405 Freeway ramps at Magnolia Street in Fountain Valley are scheduled to close soon for about a month as part of a larger freeway widening project.

The freeway off-ramp to Magnolia is set to close at 10 p.m. Tuesday and reopen March 24, according to the Orange County Transportation Authority.

The on-ramp from Magnolia is scheduled to close at 10 p.m. Feb. 23 and reopen March 24.

Detours will be in effect.

The closures will accommodate work as part of a $1.9-billion project to widen the 405 between the 73 Freeway in Costa Mesa and the 605 Freeway near Rossmoor.

Once that project is completed in 2023, both directions of the 16-mile stretch of the freeway will have an additional general-purpose lane and a new “express” toll lane, according to the OCTA. The existing carpool lane in each direction will be converted to an express lane.
