Night construction – intersection of Bonita Road and Milton Court

Next week, crews will begin night work at the intersection of Bonita Road and Milton Court to install pipelines near the new Bonita Pump Station from 8 p.m. – 5 a.m., Monday to Friday. During this time, expect temporary delays as there will be a single lane closure to accommodate equipment and materials. During work hours, the traffic signal at 74th Avenue will be turned off and flaggers will guide vehicles through the construction area. Neighbors can expect to see and hear excavators, dump trucks and lighting. After work is completed each night, the area will be backfilled and temporary paving will be placed.

Once work is completed in the intersection, about the second week in February, crews will progress onto Milton Court to begin installing waterlines from Milton Court to the pump station. During this time, single lane closures will be in affect and flaggers will be present to direct traffic. Temporary delays are expected. Once all work is complete in the roadway, Milton Court will be repaved.

Floor Slab

The rebar for the pump station’s concrete floor slab has been installed and the concrete will be poured next week.

Concrete masonry walls

Crews have finished installing the concrete masonry walls for the Bonita Pump Station. Next, a brick façade will be applied to the exterior, and a weather barrier, insulation and wall panels will be installed in the interior of pump station.

About Bonita Pump Station

The Bonita Pump Station will connect with several local water systems including Lake Oswego, Portland and Washington County. This supply collaboration will keep Tigard protected should one water supply become interrupted. Completion is expected in summer, 2015.

Did you know? Tigard's new water system’s storage reservoirs are all covered, meaning fewer opportunities for contaminants to enter the system.
