(Washington, DC) Wednesday, October 19, the District Department of Transportation (DDOT) will begin setting up the construction work zones required for the first phase of the Air Rights Tunnel Project in Northwest DC. The first phase of construction will entail work activities on the H Street and Massachusetts Avenue Bridges and the Air Rights Tunnel. K Street related work activities will be included in the second phase of construction.

Concrete jersey barriers will be used to delineate the construction work zones on the bridges and tunnel. During non-work hours the existing number of traffic lanes will be maintained on the bridges and in the tunnel.

H Street and Massachusetts Avenue Bridges

• The initial construction work zone for the H Street Bridge and Massachusetts Avenue Bridge will occupy the center travel lanes between 2nd and 4th Streets.
• Outside of the concrete jersey barriers, construction work will take place between 9 am and 3 pm Monday through Saturday and may take place on Sunday if necessary.
• Behind concrete jersey barriers, construction work will take place between 7 am and 7 pm.
• At a minimum one eastbound and one westbound travel lane will be kept open during work hours.

Air Rights Tunnel

• The initial construction work zone within the Air Rights Tunnel will occupy the northbound and southbound shoulder lanes.
• Outside of the concrete jersey barriers, construction work will take place between 9 pm and 5 am Monday through Saturday and may also take place on Sunday if necessary.
• Behind concrete jersey barriers, construction work will take place between 7 am and 7 pm.
• At a minimum one northbound and southbound travel lane will be kept open during work hours.

Access to all businesses and residences will be kept open.

Temporary signage will be posted to alert and guide the traveling public through this area. DDOT encourages all motorists to stay alert.

About the Air Rights Tunnel Project
The 18-month project will rehabilitate the bridges that are located over I-395 on H and K Streets and Massachusetts Avenue. As part of the rehabilitation efforts the bridge surfaces will be upgraded and improvements will be made to the drainage system, traffic signals, street lighting and sidewalks. Electrical-mechanical upgrades will also be made to the Air Rights Tunnel below the bridges. The upgrades will provide better lighting and air exchange within the tunnel for travelers who use the tunnel (The Air Rights Tunnel is part of what is commonly referred to as the 3rd Street Tunnel).
