Pedestrian improvements are coming to portions of Meadowlark Lane, Tree Top Lane, Carman Drive, and Pilkington Road. Shaped by feedback from the community, available roadway space, and technical analysis, designs are now complete. Visit our webpage to see more details of the final recommended designs.
Construction for Tree Top and Meadowlark is planned summer/fall 2025. Construction for Pilkington is planned for fall 2025. Construction for Carman is now planned for early 2026.
Lakeview Boulevard is always a busy corridor—with people walking, rolling, riding, and driving —but with major construction now underway, it’s more important than ever to SLOW DOWN and stay alert. Lakeview, between South Shore and Iron Mountain, is currently one-way eastbound for all vehicles and bikes. Riding your bike or driving westbound is not safe and puts everyone at risk. If you are a pedestrian, please use caution as it is very constricted with the single shared lane. There are multiple crews and utility companies working throughout the corridor, with heavy equipment and vehicles constantly moving—your attention and caution are critical.
Travelers are advised to find alternate routes, plan extra travel time, and avoid the project area. Schedules and traffic adjustments are subject to change throughout construction of this major project.
We want your help in making community streets a safer and more comfortable place. While staff work diligently on addressing issues that are spotted, we understand that we can’t catch everything.
The City is implementing a new ADA curb ramp program to address accessibility gaps, enhance safety, comply with legal requirements, promote community inclusivity, and contribute to broader infrastructure modernization efforts. By implementing a comprehensive program, the City can create a more accessible and welcoming environment for everyone.
Lake Oswego, with Portland’s support, has been using a phased project approach to replace the aging Tryon Creek plant with an environmentally sustainable wastewater treatment facility, at a good value to the community. The first phase of the project is now complete, which included developing facility designs, preliminary permitting, and proposed pricing for the Wastewater Treatment Facility Project.
For the second phase of the project, Lake Oswego will explore a competitive procurement method using public financing, to complete the design, construct the facility, and operate and maintain the facility under a long-term contract.
