General Traffic Impact Information

This work will impact traffic on multiple freeways including I-405, U.S. 30, I-5 and U.S. 26. The closures (shown on the maps below) are needed to maintain a safe work zone for the traveling public and construction staff. Significant traffic delays and congestion are expected.

Traffic impacts: 

  • Nighttime single and double lane closures throughout the project area.
  • Weekend daytime single lane closures throughout the project area.
  • Nighttime and around-the-clock weekend closures, lasting until 10 a.m. Mondays, of on- and off-ramps (detailed on map below). 
  • Full 24/7 closures of U.S. 30 east to I-405 north (18 days) and U.S. 30 east to I-405 south (11 days).
  • Closures of sidewalks, lanes and parking on local roads under I-405.


 

Ramp and Lane Closures *

Multiple weekend and overnight closures of on- and off-ramps and lanes will take place during construction. At times, multiple lanes on I-405 may close, leaving freeway traffic to share one lane in some sections.

Approximately 25 weekend closures of on- and off-ramps and lanes are expected in the project area, along with frequent nighttime closures of each ramp. Night work is needed in order to minimize traffic impacts during the day.

Around-the-clock weekend closures will start as early as 8 p.m. on Fridays and will end by 10 a.m. on Mondays for each of the ramps shown. Multiple on- and off-ramp closures may happen at the same time. Dates for each weekend closure will be posted on this website in advance.

Impact on Local Roads

During construction, local roads, sidewalks and some parking spots under the elevated parts of I-405 may close when work occurs overhead. Drivers can follow signed detours. Sidewalk detours will be signed and accessible to people with disabilities.

* All closures are subject to change and weather dependent.

Construction Impacts

Construction Noise

Periodic daytime and nighttime noise will take place, and those working or living in the area may hear the noise. 

Noise will come from heavy equipment, construction trucks, the beeping noise when vehicles are in reverse (a requirement by the Occupational Safety and Health Administration), and equipment such as concrete saws, drills and jackhammers. 

We will apply construction noise mitigation measures to reduce noise impacts to surrounding neighbors. 

Use the 24/7 nighttime noise hotline to reach a live person to discuss any noise concerns: 833-840-1107.

Schedule

March 2019 - Fall 2020
