Design Enhancements

Phase 1 includes more than ten bridge structures - where the bypass crosses over creeks, wetlands, railroads, or travels over or under other local roads. Some bridge structures will be seen by only bypass drivers or only the local community. Some structures will be highly visible to all – local travelers, bypass traffic, and nearby residences and businesses.

Community input has helped inform the design of visual elements for Bypass bridges, including unique elements for the structures over OR 99W in Dundee and along south Newberg. 

Corridor Theme: Meandering River and Rolling Hills

With input from the Yamhill County Parkway Committee, a corridor theme was designed that was applied, as possible, to bridges along the Bypass to help maintain a consistent look and feel.

The theme includes an open form for bridge structures, which allows views for drivers under the structure and provides opportunities for smooth transitions into the surroundings. A “meandering river” concrete relief is stamped into the concrete railing and an ornamental “rolling hills” design is used where screening is required. Initial concepts are shown to the right. The concepts may be refined as they are implemented.

Conceptual drawing of the corridor theme, as shown at 8th Street in Dundee. A “meandering river” relief is stamped into the concrete rail and the protective screening (required in some areas) has a “rolling hills” design. Note that Phase 1 of the bypass will include two travel lanes - one in each direction - but bridges will be built to accommodate the addition of lanes in the future. The concepts shown here may be refined as they are implemented. Conceptual drawing of the corridor theme, as shown at 8th Street in Dundee.

Bridges above the BypassBridges will have consistent design along the Bypass, with a river relief stamped into the concrete rails and a rolling hill design where screening is required. 

Newberg Area: Trees and Hills

ODOT met with a focus group of community representatives and held a public open house to inform the design of the bypass bridge structure that will pass along the neighborhood in south Newberg.

Graphic rendering of bypass crossing over River Street (looking south). Concepts may be refined as they are implemented. Design concept for retaining wall with sound wall above in south Newberg. Concepts may be refined as they are implemented. Landscaping plan between 11th Street and the bypass: Types of plantings depend on the width of the planting strip. Concepts may be refined as they are implemented. The bridge along south NewbergLandscaping will use a mix of evergreen and deciduous trees. Retaining walls will include a stone block texture. A noise wall along the the roadway (on top of retaining walls and the bridge structure) will include a pattern of trees and hills.  The concepts may be refined as they are implemented.

Landscaping next to the bridge will allow open views underneath. Concepts may be refined as they are implemented.

Dundee Area: Artistic Red Hills

ODOT met with a focus group of community representatives and held a public open house to inform the design of the bypass bridge structure that will go over the railroad and OR 99W south of Dundee.

Concept of bypass crossing over 99W in Dundee (near Niederberger Road): The new bridge over the railroad tracks and OR 99W will feature a metal river sculpture and artistic elements that evoke the red hills of Dundee. Concepts may be refined as they are implemented. Planting concept plan for stormwater pond at bypass connection with OR 99W in Dundee (near Niederberger Road). Concepts may be refined as they are implemented. The bridge over OR 99W in Dundee: The new bridge over the railroad tracks and OR 99W will feature a metal river sculpture and artistic elements that evoke the red hills of Dundee. Concepts are being further refined.
