I-5 - Interstate Bridge to 39th Street Paving - Frequently Asked Questions

Will this project impact my commute?
Daytime commuters will not be significantly impacted by paving activities.

Crews will work at night to minimize traffic disruptions. Work will generally take place between 10 p.m. and 5 a.m., and you can expect to see single-lane, double-lane and ramp closures during those hours. Crews will work longer shifts over the weekends to take advantage of hours when there are fewer vehicles on the interstate.

Most crews and equipment will be off the interstate before morning commuters hit the road, but you might see occasional morning single-lane closures on northbound I-5 while crews wrap up night time paving work.

Will the nighttime paving work be loud?
Construction noise will not be noticeably louder than regular interstate traffic.

The first step of the paving process is the loudest – crews will grind out approximately two inches of existing asphalt pavement before laying new pavement on the roadway.

On-site WSDOT inspectors have recorded grinding operations at 85 decibels. That noise decreases to 60 decibels by the time it reaches the nearest businesses and residences. That’s the level of a normal conversation and less noise than you hear when driving most cars.

Won’t the Columbia River Crossing (CRC) project pave I-5 when it goes to construction? Why not wait until then?
The CRC project will repave this section of I-5 near the end of CRC project construction. Current plans call for the CRC construction to begin in 2013 and last between five and seven years.

It has been 13 years since I-5 was paved between the Interstate Bridge and 39th Street, and the deteriorating pavement needs immediate repair. Asphalt pavement can last from eight to 12 years under heavy interstate traffic volumes, and the new road surface will carry traffic for at least six years before the CRC project resurfaces I-5 through downtown Vancouver.
