WHAT'S NEW
**The four full directional weekend closures have been completed. However, lighting, sign installation and other project elements still need to be completed. The contractor will use nighttime lane and ramp closures on I-405 to finish this work by May 31, 2010.**

LOCATION AND OVERVIEW
This project is paving Interstate 405 from the Marquam Bridge, mile post 0.38, to the Fremont Bridge, mile post 2.59 (the bridges themselves are not part of this paving project). Rutted pavement will be filled to surface grade and then paved to improve the safety of the highway. The concrete median area that is currently open will be backfilled with rock and capped with concrete. Pavement grinding will occur under four over-crossings of the freeway to maintain federal clearance requirements. New lighting and signs along the I-405 corridor also are being installed as part of this project.
PROJECT BENEFITS
The pavement of I-405 in the project area is rutted in all lanes, causing safety hazards. Traffic volumes on I-405 range from 83,000 to 125,000 vehicles per day, making it one of the busiest sections of freeway in the Portland metro area. The freeway serves as a major interstate freight and commuter route. It also is a primary detour route when Interstate 5 through the city is affected by maintenance work or crash-related congestion. New pavement will improve safety, reduce wear on vehicles, improve signing and lighting, and provide a smooth surface for auto and truck traffic.
TRAFFIC IMPACTS
The high traffic volume on I-405 requires that lanes be open during weekday daytime hours. Closing lanes would cause significant backups on I-405, I-5 and local streets. Therefore, four weekends of full directional (north or south) closures were required for the grinding and overlay paving work. Ramp paving primarily took place during the weekend closures. However, weeknight lane and ramp closures also will be used during the duration of the project to complete lighting, signing and other work. Several tunnels also will be closed during nighttime hours so work crews can update lighting.
Here is the schedule of weekend closures of I-405 that took place in summer 2009:
August 15-16
|
All I-405 SOUTH lanes and ramps will be closed
|
DONE! |
August 22-23
|
All I-405 NORTH lanes and ramps will be closed
|
DONE! |
August 29-30
|
All I-405 SOUTH lanes and ramps will be closed
|
DONE! |
September 12-13
|
All I-405 NORTH lanes and ramps will be closed
|
DONE! |
**The contractor is scheduled to complete the paving, signing and lighting project by May 31, 2010. While there will be no more weekend full closures of I-405, motorists should expect nighttime lane and ramp closures, and daytime shoulder closures while the contractor finishes all elements of this project.**
NOISE IMPACTS
The city of Portland has granted ODOT a noise permit for work on the I-405 paving project. The noise permit limits work that can take place during nighttime hours. Work taking place at night will include paving operations, which typically move along the highway at 5mph.
The 24-hour noise hotline is 503.646.0231. If you have any noise concerns please don't hesitate to call this number.

Work on the I-405 paving project began in June 2009 and is expected to be completed by May 31, 2010.
During the summer of 2009, there were 4 weekend single-directional closures of I-405. Northbound I-405 was completely closed on two weekends during this period; southbound I-405 was completely closed during two weekends during this period.
Three tunnels will be closed during nighttime work hours for approximately a week during the project. They are the Taylor Street and Everett Street on-ramps to southbound I-405, and the U.S. 26 (Sunset Highway) to northbound I-405 ramp. The tunnels will receive new lighting during the closures.
