Designer proposes modern rolling bridge cranked by hand

A new vision of an old-style bridge in London.

Centuries ago, during the height of early engineering, bridges
were considered technical marvels (they
often still are
). “Rolling bridges,” also called
retractable bridges or draw bridges, connected chasms between a
narrow waterway without blocking boats’ paths.

Architect Thomas
has envisioned a new type of rolling bridge that
playfully adapts the original 18th-century vision, and he’s now
raising money to
build one
. The architect designed the pedestrian bridge to
cross a waterway at Cody Dock, a derelict industrial area in East
London that organizations are eyeing to transform into a park.

The painted steel bridge design is connected to the banks via
teeth that hook into each other. Cranks on one side of the river
turns the bridge on rails, creating a clever mechanical system that
doesn’t need motors or electricity to move. “Rolling parallel
to the channel it crosses, this design owes much to its Victorian
forbears. They knew that moving large heavy structures efficiently
requires that they are a balanced system and my design works on
this same principle,” Randall-Page
told Dezeen

Right side up, the bridge has a simple flat span; inverted, the
bridge creates an arch that will allow boats to pass through that
channel for the first time in 50 years.

The crowdfunding campaign is currently just over 30 percent to
its goal.
