Precedent analysis
Henderson Waves
Singapore
Pedestrian bridge between parks
Areas for seating gathering in small to mid sized groups and viewing
Sundial Bridge
California
Pedestrian Bridge across water
Sensitive to solar activity, constructed with light under walkable surface, space underneath for
small to medium events.
Juscelino Kubitschek Bridge
Brazil
Vehicular traffic bridge over water
Curvilinear deck
Pont Gustave-Flaubert
France
Vehicular and pedestrian bridge over water
Hydraulic bridge can raise and lower to accommodate ships passing underneath, gathering spaces at
either end
Da Vinci Bridge
Pedestrian bridge over highway
self supporting structure
Brazil
Vehicular bridge over water
Multidirectional traffic flow
Gateshead Millennium Bridge
England
Pedestrian bridge over water
Curved deck allows it to be able to allow ships through when tilted, has benches and viewing areas
on either side and on bridge.
Tilikum Crossing
Portland
Pedestrian and mass transit bridge over water
Newly completed bridge accommodates the existing tram lines and incorporates stations at either
end of the bridge, pedestrian viewing areas also incorporated.
Initial site analysis Portland
Site 1
Burnside bridge
The Burnside bridge would be a very likely candidate for me because of its proximity to downtown, its location near the farmers market inviting further development and because of the complicated roadwork on the east side of the river.
Site 2
Morrison bridge
The Morrison bridge would also be an ideal location for my project. Though not near the farmers market it does allow for a more unique intervention on the surrounding areas. The one qualm I have with this site is the number of connections to roads on the east side of the bridge.
Site 3
SW Hawthorn bridge
This bridge has similar qualities to the first two however on its east side it passes under the interstate which could lead to a more unique design condition. Also this location is not particularly close to transit lines but perhaps there is a need then.
Potential option 4 being a new bridge in the downtown area though not likely.
All these sites I am considering. I will need to do further research into each one in order to choose the best of them for a large intervention. It may be found however that none of them are ideal and I will need to choose a new location along the river but I think each of these are likely.
Potential Program
Vehicular traffic: although many of the interesting bridges that I have studied are pedestrian I think that the challenge in part comes from successfully combining the pedestrian and the vehicular.
Pedestrian traffic: this can allow for viewing areas and gathering areas.
Mass transit/transit station: Especially in Portland but also to add another dimension to the project as well as allowing for terminals or stations at one or both ends of the structure.
Large gathering space: This could manifest itself as an extension of the farmers market for the Burnside bridge or as a open air theater in the other sites. The riverside park in Portland can help to accommodate this.
