Crews begin excavating the street in a process that will last for as long as eight weeks

PHOTO COURTESY OF CITY OF LAKE OSWEGO - A map distributed by the City of Lake Oswego shows the planned closure areas along D Avenue, with gaps at the intersections that will remain open to cross-traffic.Work crews started the road excavation phase of the D Avenue Improvement Project this week, which will require 24/7 closures of multiple portions of D Avenue between State and Tenth streets.

During the closures, D Avenue will be closed to all traffic — including bicyclists and pedestrians — except for residents whose houses are on D Avenue.

The closures are scheduled to start at First Street and proceed east to west, beginning on July 16 with the segment from First Street to Fourth Street. Next will be the segment from Fourth to Seventh, then the segment from Seventh to Tenth. The project will then loop back around and close the segment from State Street to First Street.

Segments will close one at a time as the excavation crew works its way up the street, but all of the closures are expected to start either this week or next week and last up to eight weeks, according to project information specialist Katy Kerklaan.

During the closures, north-south access will generally be maintained through the intersections of D Avenue at First, Fourth, Seventh and Tenth streets, although there will be short-term closures at those intersections while the road is being excavated. Pedestrians and bicyclists are encouraged to make use of those four crossings.

Residents on the closed portions of D Avenue will retain access at most times, although there will be occasional periods when driveways will be blocked. There will be no on-street parking on D Avenue during construction, so visitors will need to park on other streets.

Access to D Avenue from all of the alleys between the main neighborhood streets will be cut off, but the alleys themselves can still be accessed from C or E avenues. Mail delivery and garbage services for D Avenue residents will not be impacted during the closures.

During the 24/7 closures, there will be no open periods due to the intense amount of construction being performed, according to Kerklaan.

During previous daytime closures, Kerklaan says project crews have noticed a number of people ignoring the road closure signs and passing through off-limits areas, especially pedestrians. But the city is strongly encouraging travelers to obey the posted signs, especially as the project moves into the excavation phase.

"This is going to be different because the whole road is going to be torn out and the sidewalks removed," Kerklaan says. "It's not going to be a safe place for people to be walking."

The excavation team will be followed by concrete crews who will begin work on sidewalks and bioswale planter areas. The block of First Street between D and E avenues will also be closed for up to three days during the first round of paving.

The crews hope to have D Avenue reopened during non-work hours by late August or early September, Kerlaan said, although daytime closures of parts of the road will continue past that point.

During the closure phase, the excavation work is expected to produce noise, dust and vibrations, and Kerklaan said the City thanks nearby residents in advance for their patience.

"We're just letting folks know to expect that," she said.

The City has begun to closely monitor the D Avenue Improvement Project worksite due to repeated incidents of vandalism and littering.

A temporary construction trailer located near the intersection of Tenth Street and C Avenue was recently vandalized when someone smeared dog excrement on the side of it, according to project officials, and there have been multiple instances in which several bags of dog excrement have been left throughout the site.

Lake Oswego City Code mandates that all dog owners promptly clean up after their pets in public spaces. Any suspicious activitiy can be reported to the Lake Oswego Police Department at 503-635-0238.
