Three lanes on the northbound I-405 will be closed between Montana Avenue and the Getty Center off-ramp for 55 hours starting Friday, March 1. The contractor will pave the future High-Occupancy Vehicle lane and realign the I-405 in this area during this time.

The southbound I-405 and Sepulveda Boulevard will remain open. All northbound freeway lanes and ramps will reopen to the public by 5 a.m. on Monday, March 4.

Here’s the full press release from Metro:

Beginning Friday night, March 1, 2013, the I-405 Sepulveda Pass Improvements Project will reduce the northbound I-405 from five lanes to two between Montana Avenue and the Getty Center off-ramp in West Los Angeles for 55 hours.  The contractor will pave the future High-Occupancy Vehicle lane (HOV) and realign the I-405 in this area. Motorists are advised to anticipate potential delays when traveling through the 2.4-mile lane reduction area and take alternate northbound routes if necessary.

This is not a full freeway closure.  The Southbound I-405 will be open and Northbound Sepulveda will remain fully operational with two lanes throughout the 55-hour lane reduction period.

The three closed freeway lanes and their corresponding on ramps will be closed for an extended 55-hour duration to enable the contractor to shift k-rail, grind existing pavement, place and compact new pavement and stripe new pavement in the freeway’s center lanes.  These activities will enable the contractor to realign this portion of the I-405 to incorporate a future northbound HOV Lane.  The HOV lane now under construction will ultimately extend 10 miles between the I-10 and U.S. 101 and complete the last remaining gap in the I-405 HOV lane network.

All northbound freeway lanes and ramps will reopen to the public by 5 a.m. on Monday, March 4.  The current weather forecast does not call for rain; however, if that changes, the operation will shift approximately one week. A schedule for lane and ramp closures is as follows:

Lane Reductions

• At 10 p.m. on Friday, March 1, the #1 lane on Northbound I-405 from Montana to Getty off-ramp will close.
• At 11 p.m. on Friday, March 1, the #2 lane on Northbound I-405 from Montana to Getty off-ramp will close.
• At 12 midnight on Saturday, March 2, the #3 lane on Northbound I-405 from Montana to Getty off-ramp will close.

Ramp Closures

The Northbound Getty and Northbound Moraga on-ramps will be closed at 10 p.m. March 1 until 5 a.m. March 4

• The Northbound Montana and Northbound Moraga off-ramps will be closed at 10 p.m. March 1 to 5 a.m. March 4.
• At the completion of the work the Northbound Getty on-ramp will remain closed for five months.

Westbound Wilshire Boulevard to Northbound Sepulveda will be used as an alternative route for those who wish to bypass the lane reduction area. They will enter Northbound I-405 again at Skirball Center Drive.

Changeable message signs and traffic control officers will be deployed at key locations within the project area to help guide motorists through the area.  Emergency access will be provided through the lane reduction area.
