Cross-traffic will be blocked at all but two intersections, project officials say

PHOTO COURTESY OF CITY OF LAKE OSWEGO - Crews have poured the concrete that will form the new edges of D Avenue for enhanced drainage. The first layer of central asphalt is scheduled to be poured Aug. 23-24.The D Avenue Improvement Project project enters the paving phase this week.

Crews are scheduled to begin placing the first three-inch base layer of asphalt along the entire 10-block length of D Avenue from Thursday through Saturday, Aug. 23-25, which will result in the closure of the entire road.

Only the State Street and Tenth Street intersections with D Avenue will remain open while the asphalt is cooling; all other north-south traffic will be blocked from crossing D Avenue, including at the intersections that have previously been open at First, Fourth and Seventh streets.

Soon after, crews will pave First Street between D and E avenues, which will require neighbors with driveway access to First Street to park on side streets. Those neighbors will be notified with a door hanger 48 hours in advance of paving.

The paving work will involve the use of roller machines to compact the rock and asphalt, officials say, which will create increased noise and vibration from the site.

In recent weeks, crews have been pouring concrete for the curbs at the corners of the intersections, as well as concrete edging that will line the road. The edging will be flush with the final road surface but slightly slanted in order to facilitate better drainage. In order to speed up the pouring process, crews will be working on Saturday, Aug. 25, from 8 a.m.-6 p.m.

Crews are hoping to be able to reopen the entire 10-block length of D Avenue by Aug. 27, in time for the start of the school year. However, intermittent daytime closures of parts of the road will still occur in the coming months while crews work on the stormwater rain gardens, sidewalk and bollard lighting.

There will also be one more full closure of the entire road at a yet-to-be-determined time while crews pour the final top layer of pavement.
