The images below show the various parts of a bridge that are under design consideration. While the bridge form considers the overall shape of the bridge and is the most fundamental part of the design, the other parts can be enhanced with features and/or artwork that represent the desired theme of the community.

PEDESTRIAN BRIDGE: THEME OPTIONSNATURAL THEME NATIVE AMERICAN THEME HISTORIC THEME

The Natural, Native American, and Historic themes represent desires expressed by the community at NSC charrettes. The photos in each theme represent the look and feel of potential concepts that emerge from the theme.

The Natural Theme is inspired by the Spokane River and surrounding wildlife. Bridge concepts under this theme may include:• Focus on experiential use of the bridge and surrounding area• Clean, streamline forms that immerse users in nature with minimal visual barriers

between users and the natural surroundings• Inclusion of artistic details that celebrate the river and fish, especially Redband Trout• Use of weathered materials that reflect exterior conditions• Planting of vegetation on the bridge for literal expression of nature• Use of curving forms to represent organic shapes of nature

The Chief Garry Theme is inspired by the history of Chief Garry and theSpokane Tribe. Bridge concepts under this theme may include:• Inclusion of artistic details that celebrate Spokane Tribal culture and Chief Garry• Interpretive signage explaining the history of the Spokane Tribe• Potential for experiential use of the bridge and surrounding area, such as designs on

the underside of the bridge that can be seen from passing kayaks and canoes

The Historic Theme is inspired by 1) historical activities that have (or still do) occur in adjacent neighborhoods and 2) existing bridges in Spokane that have set a precedent for design, especially over the river. These concepts emerged from charrette comments that mentioned general history of the area as well as specific activities. Bridge concepts under this theme may include:• Chief Garry Park aeronautical / aviation activities; Minnehaha historical film and

mineral spa activities; historic streetcar lines and art deco architecture• Focus on design of bridges that have historically been built in Spokane• Use of arches and tresses in bridge design, inspired by bridges such as the Greene St

Bridge, in either the structure or other features of the bridge

Spokane River Pedestrian Bridge: Theme Options There will be a separated pedestrian bridge spanning the Spokane River to the east of the Greene Street Bridge and North Spokane Corridor. Through this survey, we continue to gather community input on elements such as lighting and railing to help inform the overall theme and design of the Children of the Sun pedestrian bridge. The Natural, Native American, and Historic themes represent desires expressed by the community at NSC charrettes. The photos in each theme represent the look and feel of potential concepts that emerge from the past community engagement efforts.

Q30 Results Summary: 59 respondents gave an open-ended responses. Among the responses there were several themes that emerged. Most responses emphasized a need for the Trail and Placemaking activities to reflect a simple and natural design, to remain sustainable. Not only did respondents want to ensure that certain amenities were incorporated in the design, but that it was affordable. People feel that a balance must be maintain between roadway configuration and bicycle and pedestrian safety. Of course the space needs to be safe and accessible for all, and should be useable all year long.

Note: Some comments reflected more than one theme.
