Get the latest information on current work underway to restore the U.S. Capitol Dome during the Dome Restoration Project:

Update: September 2014

Construction task lighting is now visible on the Capitol Dome in support of the Dome Restoration Project. The lighting is installed to help workers as they restore the Dome at night. Lighting of the project site will continue as the scaffolding is assembled up the Dome.

Scaffoldin​g and Restoring Phase

With the completion of the safety netting installation inside the Rotunda, work on the towers and bridge on the West Front continues. The scaffolding assembly on the Dome (currently visible at the Peristyle level) will continue upward and is scheduled to be completed in late 2014. As certain portions of the scaffolding are completed, repairs on the cast iron can begin.

Dome Restoration Project​ Mobilization

In support of the Dome Restoration trucks deliver equipment and supplies to the East and West Fronts of the U.S. Capitol. These deliveries occur between 6 a.m. and 3 p.m. Flagmen direct pedestrians to use the sidewalk during the delivery process for safety. If a pedestrian is unable to use the alternate sidewalk due to the need for wheelchair accessibility or other accommodation, then the flagmen will direct the truck traffic to stop and allow the pedestrian to safely pass on the sidewalk. Additionally, a staging area has been established on the northwest lawn of the U.S. Capitol for the duration of the project.
 
The plan below shows the truck route (red), the pedestrian route during deliveries (blue) and the staging area (yellow).
