Daytime closures along Seal Beach Boulevard for construction on the 405 Freeway Bridge caused traffic jams around Christmastime that prompted some to complain of the inconvenience. However, local and county authorities determined the work had to go on.
More closures in the area are scheduled as the work to ultimately improve the traffic flow and keep people moving are planned. The work will take placed during the late night and early parts of the morning to lessen the impact.
Nighttime closures are currently scheduled through Saturday night, Feb. 4, to allow for crews to pour the stem and soffit at the 7th Street Bridge, roadway paving, earthwork, setting k-rail, roadway striping and falsework construction.
The northbound I-405 (between Seal Beach Boulevard and the I-605 freeway) will be closed from 11 p.m. on Monday night, Jan. 30 until 5 a.m. on Tuesday, Jan. 31.
The southbound I-405 (between the I-605 Freeway and Seal Beach Boulevard) will be closed nightly, Tuesday, Jan. 31 through Thursday, Feb. 2. On Friday night, Feb. 4 and Saturday night, Feb. 5 the southbound I-405 will be closed between 11 p.m. and 7 a.m.
Closures are scheduled through Saturday night, Feb. 4, with specific times listed below. However, due to unforeseen operational factors or inclement weather, these dates and times are subject to change.
These full northbound I-405 freeway closures are necessary as part of the northbound I-405 / westbound SR-22 / 7th Street connector reconstruction. Crews will perform the closure in order to erect false work over the freeway for the 7th Street bridge.
