As part of Metro's investment in safety and reliability, construction will begin in July on the first of two major capital projects on the Red Line that will upgrade the tunnel ventilation system and repair deteriorating platform canopies. The work is expected to cause significant impacts for customers, with around-the-clock single tracking and station closures.
'It is important that we continue with this safety critical work so that we are ready and able to resume normal operations as the region reopens,' said Metro General Manager Paul J. Wiedefeld. 'We will be working around the clock, seven-days a week, to maximize efficiencies and allow us to get the work done more quickly.'
Beginning Saturday, July 17, and continuing through Sunday, August 29, Metro and its contractor will install new, more powerful fans in the tunnels between Woodley Park and Cleveland Park as part of a pilot project to improve tunnel safety in the event of a smoke or fire emergency.
The 24/7 schedule will help Metro reduce the duration of the project and minimize the impact to customers. During construction, trains will continuously single track between Dupont Circle and Van Ness. Crews, working in the tunnels more than 100 feet below Connecticut Avenue, will install the necessary infrastructure and new evacuation fans at the base of the ventilation shafts.
Two weekend shutdowns will also be needed, with free shuttle buses replacing trains this summer. Additional weekend closures will be necessary in 2022 to complete the project, commissioning and safety testing.
The tunnel ventilation project was developed in response to a National Transportation Safety Board (NTSB) directive to upgrade tunnel ventilation after the 2015 smoke incident at L'Enfant Plaza.
As the oldest line in the Metrorail system, the Red Line ventilation shafts and fans were installed prior to the establishment of the National Fire Protection Association (NFPA) safety standards for transit systems.
Following the completion of the ventilation upgrades, Metro will begin work in September to replace the platform canopy at Rockville, with additional canopy repairs at Shady Grove. The steel and glass structures, original to construction in the 1980's, are deteriorating.
The canopy project will take three months and require the closure of the Rockville and Shady Grove stations from September 11 through December 4. Free shuttle bus service will be provided to/from the closed stations.
Replacing the canopy at Rockville Station will require heavy equipment and the demolition of the existing structure, section by section. The new canopy structure will be pre-fabricated and lifted into place for installation.
Additional customer improvements will also be made to the canopy, including new, more efficient LED skylights, upgraded speaker system for station announcements, new digital screens for passenger information and new CCTV cameras for improved security among others.
During this time, Metro will also make repairs to the aging canopy at Shady Grove Station and perform other safety critical work to enhance service for customers.
The ventilation improvements and canopy rehabilitation projects are funded through Metro's 6-year, $9.7 billion Capital Improvement Program, which invests in system safety, reliability and the region's economy.
