Architect Thomas Randall-Page has started a crowdfunding campaign to support the construction of a unique rolling bridge in London. The project, which has been nicknamed the Cody Dock Rolling Bridge, proposes building a small-scale pedestrian span over the narrow canal of Cody Dock that flows into the River Lea, which in turn connects to the Thames. According to the crowdfunding page, the design will open Cody Dock to boats for the first time in half a century and has already received approval from the Newham Council and support from Mayor Sadiq Khan.
Randall-Page describes the project as both innovative and highly contextual. It makes material reference to the area’s history of iron production while taking certain stylistic cues from the industrial design of Britain’s Edwardian era. The most distinctive aspect of the proposed design, though, is its rolling motion. The bridge runs along a pair of twin, undulating rails that are attached to the brick walls on either side of the canal, and can roll a full 180-degrees so that its floor becomes its roof. In the latter position, the bridge’s arch can accommodate barges and other boats as they move through Cody Dock.
Compared to other operable bridges, the controls of the Cody Dock Rolling Bridge are quite simple. Teeth alongside the edge of the bridge’s frame fit into notches between teeth on each rail, enabling the entire structure to roll in a steady, gear-like motion. Counterweights are built into the rounded square frame of the bridge, which prevent it from rolling uncontrollably or getting stuck in any one position. A single cable attaches the structure’s frame to a crank handle, which a person can turn to invert the bridge.
The Cody Dock Rolling Bridge forms one link in the broader redevelopment of one of London’s industrial areas. The pedestrian bridge will connect walking and bike paths on either side of the canal, allowing easier access to new artists’ studios, exhibition spaces, fabrication workshops, and a cafe along the banks of the Lea. Proponents of the design hope that the structure will serve not only as a critical piece of infrastructure but also as a compelling landmark that will attract visitors from across the city. Now in the final stretch of their fundraising effort, Randall-Page and the bridge’s supporters hope to raise upwards of $200,000 towards the completion of the project.
Currently the only link between the rapidly developing neighborhoods of Long Island City, Queens, and Greenpoint, Brooklyn, is the Pulaski Bridge, a six-lane drawbridge with a narrow pathway where pedestrians and bikers jostle for space. Brooklyn-based CRÈME/Jun Aizaki Architecture & Design wants to change that by proposing the LongPoint Bridge, a 250-foot-long crossing dedicated to foot and bike traffic.
The bridge is distinguished from its counterparts across the city for its lightweight, floating timber construction. It is anchored on either end by a concrete and steel mast embedded into the waterbed of Newtown Creek (the East River canal that divides Queens and Brooklyn). Glulam beams joined by galvanized steel braces and pins rise in two trussed peaks of armature around the nearly 50-foot-tall masts. The structure is a nod to the area’s industrial past and present while also referencing the iconic profiles of other bridges in the city. Its height above the canal allows smaller vessels to pass underneath, but for larger boats, the bridge pivots open in the middle, with each section moving on propeller-driven pontoons. This floating feature also allows the bridge to rise and fall with the tides.
According to Jun Aizaki, the firm’s founder and principal, the bridge’s design and timber composition allows it to be assembled off-site and installed quickly and inexpensively; in the long term, it will require only minimal repairs. CRÈME also proposes public parks and loading docks to flank the bridge on both ends, along with a pedestrian crossing over the Long Island Railroad commuter rails just beyond the canal. Together with the timber bridge, the pathway would connect commuters to the G and 7 trains on either side.
With the impending L train shutdown in 2019 and the predicted growth of Long Island City as it hosts Amazon’s HQ2, the timing of a quickly constructed, relatively affordable bridge seems ideal. Aizaki and his team, which includes a community organizer, are busy raising support and funds through meetings with public officials and local community members. For Aizaki, the bridge is intended as “a grassroots, rather than developer-initiated, project,” which he hopes will “be a symbol of something the community can be proud of."
Louisvillians lament that new highways won’t solve the city's congestion problems, though the increased number of options to pass through the city are a bonus for anyone who doesn’t wish to make a pitstop on their way somewhere bigger and better. It’s a classic, tragic story that’s hurt many American cities suffering from mid-century highway build-outs. Some are making concerted efforts to replace aging infrastructure with beautiful boulevards and walkable, shared streets, but others aren't thinking as clearly about how to keep people in town, as opposed to letting them drive on by. Kentucky’s busiest bridge, the Sherman Minton, sits further outside downtown than its counterparts. As the city’s only toll-free link to Indiana, it sees 90,000 drivers per day. The 56-year-old structure is slated to begin a $90 million rehabilitation project in 2021. Time will tell whether or not its partial or full closure during construction will force people to start crossing the newer structures that spew out of the city’s core. The Indiana Department of Transportation and the Kentucky Transportation Cabinet just ended a public input period to figure out next steps. A recommendation will be made next fall.
There are bad highways projects and then there’s this...I visited Louisville with @cnunextgen in 2014 & remember thinking this project couldn’t be real. $1.3 billion later... traffic volume has been cut in half, riverfront is cut-off & development has been hindered. https://t.co/5u8415JMEB — Nate Hood (@natehoodstp) November 28, 2018
