​Traffic Impacts
  • Periodic day and nighttime lane closures on OR 99W northbound throughout construction.
  • Bicyclists will travel in the lane of traffic through the work zone.
  • The speed limit on OR 99W northbound across the bridge is reduced from 45 MPH to 35 MPH during construction.​

Construction Impacts

Construction Information

Construction continues at various times throughout the day and night, though workers may not always be visible to the public. Daytime and nighttime construction noise should be expected from time to time, and those working or living in the area may hear the noise. 

A 24/7 nighttime noise hotline is available at 971-673-5239 for any noise-related concerns.

Pavement work is weather dependent, where temperatures and moisture levels matter. This is why this work is scheduled for this time of year, when the weather is more predictable.

Schedule

Construction began in August 2020 and will continue through the end of 2020. ​

About

ODOT began work in August 2020 to repair the bridge over the Tualatin River on Oregon 99W northbound, between Tigard and Tualatin. This work includes replacing the bridge joints and installing new concrete surfaces and will last through the end of the year. These repairs will improve the condition and maintain the long-term safety and use of this heavily traveled highway.

Why is This Work Needed?

The bridge is constructed in segments, connected by concrete to concrete joints with joint seals. Over time, the road surface has worn down and begun to crack. It is now in need of repairs. Crews are replacing the joints and the road surface, extending the life of the bridge for 20 to 30 years.​
