Dome Restoration Project Updates

Scaffoldin​g and Restoring Phase

Large containment areas that were on the U.S. Capitol Dome during the major paint removal process are gone. The project continues with cast iron repairs and painting.

Construction task lighting is visible on the Capitol Dome in support of the Dome Restoration Project. The 720 LED construction task lights are installed to help workers as they restore the Dome at night.

Below is the latest information on current work underway to restore the U.S. Capitol Dome.

New U.S. Capitol Dome Cupola Windows

In August 2015, new glass was rolled and trimmed to replace the badly damaged and unstable historical cupola windows. The glass was made using a traditional process, similar to what was used to create the original 1860s windows. This method is used to recreate the wavy "metal chilled" surface texture of the current windows while updating them to today's standards. The glass panels were then laminated with a polyurethane resin, which improves the safety and durability of the glass.

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).
