At long last, the northbound I-405 off-ramp at Sunset is ready to re-open, marking another 405 project milestone. This closure was the longest yet, clocking in at almost four months. The contractor had a ton of work to do to complete the ramp, which now has 60 percent more capacity and two eastbound turn lanes to Westwood/UCLA.

End of Sunset Boulevard “Ramp Jam”
Northbound I-405 Off-Ramp at Sunset Boulevard in West Los Angeles To Reopen Monday Morning, November 25 Following Nearly Four-Month Closure
The Los Angeles County Metropolitan Transportation Authority (Metro), California Department of Transportation (Caltrans), and contractor Kiewit Infrastructure West will re-open the northbound I-405 off-ramp at Sunset Boulevard in West Los Angeles by 6 a.m. Monday morning, November 25, ending a 120-day ramp closure one week ahead of schedule.
The new, seismically updated ramp will have nearly 60 percent additional length and capacity to store vehicles and segregate traffic from Sunset Boulevard and the northbound I-405. By lengthening the ramp, the project has added the capacity for an additional 25 vehicles on the ramp. Now 50 vehicles can queue on the ramp rather than the I-405.
The new ramp configuration features two northbound right-turn lanes to eastbound Sunset and one northbound left-turn lane to westbound Sunset. The previous ramp only had one turn lane in each direction. The extra eastbound turn lane capacity will benefit drivers traveling to the busy Westwood/UCLA area. Approximately 9,600 vehicles utilize the Sunset off-ramp per day, according to Caltrans figures.
On Sunday, November 24, the project will close the off-ramp at Montana Avenue permanently to continue construction of an additional traffic lane on the northbound I-405.
The reopening of the Sunset off-ramp marks the end of “Ramp Jam” at Sunset. All Sunset Boulevard improvements, including higher capacity bridge, higher capacity on- and off-ramps, Church Lane undercrossing widening and area retaining and sound walls constitute some of the most significant improvements for the I-405 Sepulveda Pass Improvements Project.
