City selects design for Confluence Park bridge

Park Planner Jenn Fink presented the arch design to the Issaquah Park Board Monday night.

Staff of the city of Issaquah have selected a design for an Issaquah Creek-spanning bridge in Confluence Park.

Picking from five designs submitted by David Evans and Associates, staff selected a timber arch bridge (pictured) with railings “meant to evoke a mayfly’s wings,” according to a description provided by city Parks and Recreation.

Park Planner Jenn Fink presented the arch design to the Issaquah Park Board Monday night.

Parks and Recreation presented the five options to the public for input in November. Alternatives included a faux cable-suspension bridge, a prefabricated steel truss, a precast concrete girder and a steel tub girder design which staff noted could have been wrapped in vines.

Of 136 pieces of public input received online, the timber arch received the greatest quantity of favorable comments. Supporters praised the use of wood materials to blend in with the natural surroundings.

“My favorite for this park,” one supportive comment read. “Looks natural, like a tree bending and also is a bit reminiscent … of the original I-90 bridge — so a bit of a nod to history.”

The design invited detractors as well. The most common criticism was that the arch was too large and overstated for humble Olde Town. Others noted that the arch could be unsafe if children attempted to climb it.

One particularly grim comment read: “Looks like a perfect place to hang people!”

The bridge, planned for construction later in 2016 as announced by Mayor Fred Butler in October during budget proposals, is part of a larger improvement campaign for Confluence Park off Rainier Boulevard North.

Parks and Recreation staff also selected a playground to be constructed on the northeast corner of Confluence. The design, supported by public input in November, is a climbing playground based in asymmetrical “natural” design. It includes a Palisades climbing boulder and beat out two symmetrical tower designs constructed out of netting.
