Connecticut Avenue NW and Nebraska Avenue NW Roadwork Leads Midweek Commute Delays

Midweek Traffic and Transit Overview

Good morning, Washington D.C. commuters. For Wednesday, March 4, 2026, residents should prepare for several active work zones and transit adjustments that may impact the morning and evening rush hours. While major arteries like I-395 and I-66 are currently flowing without reported major accidents, significant infrastructure projects across the District are causing localized lane closures and diversions that require extra travel time.

Major Road Closures and Construction

The District Department of Transportation (DDOT) has several ongoing projects that are affecting key corridors this morning:

• Connecticut Avenue NW: Deckover work continues between Q Street and Dupont Circle. Commuters should expect the closure of service lanes in this area, which is significantly impacting local traffic flow and parking availability near the circle.
• Nebraska Avenue NW: A sidewalk repair project is currently active from Tenley Circle NW to Davenport Street NW. Motorists should be alert for intermittent lane shifts and increased pedestrian activity around the work zones.
• Maine Avenue SW: A recent traffic pattern change remains in effect for the access road to 14th Street SW. This adjustment is part of the ongoing improvements near the Wharf area and may be confusing for drivers who have not navigated the intersection recently.
• Independence Avenue SW: Sidewalk and roadway repairs are underway between 9th Street SW and 12th Street SW. These blocks often see heavy bus traffic, so commuters should anticipate minor delays near the Smithsonian museums.
• Pennsylvania Avenue SE: Roadway projects between 27th Street SE and Alabama Avenue SE are continuing to cause delays for those traveling toward the Maryland border.
• 22nd Street NW: DC Water and DDOT emergency sewer repairs remain active between P and Q Streets. The northbound lanes are restricted, and detours are in effect for those heading toward Massachusetts Avenue.

Public Transportation and Metrorail Alerts

The Washington Metropolitan Area Transit Authority (WMATA) reports that all six Metrorail lines are operating, but weekday service changes are in effect. Riders should check display boards at stations for updated train frequencies. Specific alerts for today include:

• Mt Vernon Square Station: The back elevator servicing the platform and mezzanine levels is currently out of service for rehabilitation. This work is expected to continue through early April, and passengers requiring elevator access are advised to use alternate entrances or nearby stations.
• Judiciary Square: Construction remains active at the north entrance for staircase and canopy improvements. While the station remains open, commuters should follow posted signage for entrance detours.
• Metrobus: At least seven bus alerts are active this morning due to ongoing roadwork and detours, primarily affecting routes in Northwest and Southeast D.C.

Commuter Advice

For those utilizing the I-95 and I-495 corridors, dynamic pricing on the Express Lanes is expected to peak between 7:30 a.m. and 9:00 a.m. Standard bottlenecks at the Springfield Interchange and the Woodrow Wilson Bridge are currently showing typical midweek volume. Commuters are encouraged to utilize transit where possible or allow an additional 15 to 20 minutes of travel time if driving through the Dupont Circle or Tenleytown areas.
