ROSSLYNK

Rosslyn
Rosslyn is a heavily urbanized unincorporated area in Northern Virginia located in the northeastern corner of Arlington County, Virginia, north of Arlington National Cemetery and directly across the Potomac River from Georgetown and Foggy Bottom in Washington, D.C. Rosslyn encompasses the Arlington neighborhoods of North Rosslyn and Radnor/Ft. Myer Heights, and is located east of Courthouse, another urbanized Arlington neighborhood. Characterized as one of several “urban villages” by the County, the numerous skyscrapers in the dense business section of Rosslyn make its appearance in some ways more urban than nearby Washington.
Downtown Rosslyn
Densly constructed area where highrises finds there home. It is highly populated during the daytime. However there are hardly much human activities on the street surface.
City Forest
One of the most unique places in the country becase right outside of the densly constructed area, there lies a massive forestry area that contains large amount of various of wildlife. Also because the green is managed by National Park Service, it is hard to make any changes through out the place.
Succession
Ecological succession is the observed process of change in the species structure of an ecological community over time. The time scale can be decades, or even millions of years after a mass extinction. This project is based on the concept of succession. The pop-up retail bridge, the beach, plants on the crossing bridge, and the self cleaning biofilter stream changes over time, giving different experiences through out its lifetime.
I-66 Highway/GW Parkway
Lee highway and George Washington Parkway seperated the downtown area from the waterfront physically so that most urban population was not able to get close to the water
Lawn / Park
By getting rid of some trees on the slope, a new grass area is created for resting and outdoor activities, enclosed by trees against the parkway and the off-ramp
Path
As an extension of part of the Mont Vernon Tarail, a path connects the park area and the bridge leading to rosslyn
New Crossing Bridge
A new crossing bridge with water features is constructed for both Mont Vernon Trail and storm water run-off.
Arlinton Beach
Based on the sedimentat collected by the groyne wall, and a layer of fine sand, Arlington Beach provides area for water-friendly activities. And the beach will keep growing as time goes by
Groyne Wall / Harbor
100 into the water, the groyne wall functions as a harbor, providing docking for food boats and water taxi, as well as the storage for kayaks.



Using the existing storm water system as a wall to collect storm water runoff, and adding a major line following the existing one, leading to the open area and have the dirty water exposed and filtered by layers of biofilter through out the long way going down to the waterfront. The purefied water will run across the bridge and inject into the Patomac River.
By changing the route of Mont Vernon Trail, a new crossing bridge carries filtered storm water through GW parkway, creating water features at the end. Storm water bio-filter along the trail cleans the water coming from major storm water pipeline. An urban lawn for outdoor activities formed on the off-ramp slope by getting rid of the existing trees, enclosed by trees next to the roads.
Simple Construction
Columns - girders - Beams - Modules
Fast installation with remote machinines
Prefabricated Modules
24 ft x 8 ft x 8 1/2 ft Steel framing moduler system
has built-in power line and lights
fitswith standard shipping
Modules within Modules
2 ft x 8 ft stadard lightweight panels stored at storing area that could be used for constructing temperary walls and roofs creating new commercial and event spaces through out the bridge


Inspired my Ponte Vecchio, pedestrian bridges with modulers that people could add or change programs, connecting Rosslyn and the waterfront. The prefabricated bridges breaks the barrier between downtown and water created by Lee Highway and GW Parkway, leaving the smallest carbon footprint. The bridge it self grows over time and adapts to the environment and time. The beach formed by groyne wall and harbor creates a new destination for people.

Meeting Point
In between the Lee Highway and George Washington Parkway, a framed structure provides three different means of getting to where people wanted to go; stairs, slides, and elevator. The upper level, lower level of the pop-up retail modular bridge and a path leading to the open area meets up at the meeting point where there are possibilities for even more activities.
Mont Vernon Trail
Redirected Mont Vernon Trail running through the bridge
with a couple of look out points
people could rest while enjoying the view

Pre-Fab Structure
For maximum efficiancy, prefabricated structural elements is used in the project
Programs
Elevator for handicapped people
and Public Restroom are provided to public use on the bottom of the crossing bridge
Water Way
Filtered Storm water runs through the prefabricated channel, forms a water fall at the end of the bridge
Vegetation grows in the water that brings livelyhood to this structured element which could be used as a bridge for animals to cross as well.

Playground
A sandy playground surrounded by a thin layer of water that alows kid to play with filtered water without any danger of getting too close to the river
