Are you doing anything to protect the viaduct from settlement?

Tags: winter-closure

Like most other structures, the viaduct was designed to withstand some settlement. We have taken a number of steps  (pdf 913 kb) to reinforce the viaduct and strengthen the soil beneath it. In 2012, crews installed angled underground walls around the viaduct’s footings to create a barrier between the machine and the structure. They also wrapped portions of the viaduct in carbon fiber to provide additional strength.
