The Oakland Bay Bridge has been in the news because of the massive maintenance project which has been undertaken on the aging structure. While some bridges need to be built with functionality in mind, others can indulge in some design experimentation. The Rolling Bridge in London’s Grand Union Canal was designed by Heatherwick Studio to retract and roll into an octagon to allow boats to make use of the canal. This YouTube video shows how the bridge operates:

The Oakland Bay Bridge in Northern California will be closed over the Labor Day weekend for seismic upgrades. The work entails moving a 288-foot piece of the bridge that weight 3300 tons to make room for its replacement. Before the replacement span can be built, a temporary bypass will be built to allow traffic to be diverted from the span that’s being replaced. This fascinating YouTube video shows a simulation of how the Bay Bridge bypass will be installed:
