I-90 - Lake Washington Floating Bridges - Anchor Cable Replacement - Project Photos

One of the old and frayed cables is coiled on a large spool after it was removed from Lake Washington.
One of the old cables is spooled on the work barge. The rust and corrosion is clearly visible. Many of the individual strands of steel that make up the cable have broken.

The divers take the plunge into Lake Washington with video cameras mounted to their helmets and a cable that provides a live feed back to the work barge. This allows workers on the barge to monitor the diver and see the work at the same time. This photo is of the monitor in the dive shed. The divers are working in dark and murky conditions at the bottom of the lake.

A diver resurfaces after spending nearly two hours in the lake. So that diver can concentrate on the anchor cable replacement, a team on board the work barge controls the technical aspects of the dive including monitoring his oxygen supply and his time below the surface. When it's time to resurface, the diver simply enters the cage and he's hoisted up. The support team on board controls his ascent, including required decompression stops.

 This large photo shows a close-up view of an anchor cable inside a pontoon on one of the Lake Washington floating bridges. This photo was taken during a previous anchor cable replacement project.
This is the anchor cable saddle inside a pontoon on the I-90 bridge. The anchor cable saddle guides the cable and holds it in place. The cable connects with anchors on the bed of Lake Washington. This photo was taken during a 2010 project to replace some anchors on the I-90 and SR 520 floating bridges.
