UPDATED Traffic Advisory: Street improvements to close lanes on SW Columbia St from SW Broadway to Naito Parkway April 21 and 22

Update (April 20, 2015) – To complete this project, PBOT crews are scheduled to pave this stretch on Tuesday, April 21 and Wednesday, April 22,  7 a.m. to 5 p.m. Lane closures will be in effect during those times. This work is weather-dependent and the schedule may change.

(April 3, 2015) - The City of Portland Bureau of Transportation advises the traveling public that street improvements will require lane closures on SW Columbia Street from SW Broadway to SW Naito Parkway from Tuesday, April 7 through Monday, April 13 7 a.m. through 5 p.m. each week day. 

The lane closures will allow crews to prepare the road surface to pave .96 lane miles.

PBOT street improvement crews work in almost all weather conditions, adjusting tasks based on conditions. Crews will grind down old asphalt and prepare street surfaces for paving even in cold and rainy weather. They will return to complete paving during a window of dry weather.

Streets with ground down surfaces are open for travel. Lane closures are only in effect during project hours. Access will be maintained for businesses and residents during the project.

The traveling public is advised to expect delays while repairs are being made. We ask the public to travel cautiously, observe all lane closures and directions by flaggers, and use alternate routes if possible.
