A project to modernize the overhead utilities and install new life safety systems in the tunnel between the Rayburn House Office Building and the Capitol Building is expected to last through 2016. The work includes installing fire alarm, sprinkler systems, energy efficient lighting and a new ceiling above the pedestrian walkway.
Intermittently throughout the year, the pedestrian walkway will be closed for demolition of the existing ceiling from 9 p.m. to 6 a.m. Signs will be posted to detour pedestrian traffic during evening closures. Once demolition is complete, the tunnel will re-open to pedestrians. In addition, subway service to and from the Rayburn House Office Building will be reduced to one operational car when Congress is not in session.
