DDOT describes the work as a twenty-four-hour, two-lane closure tied to DC PLUG feeder 467. In the same corridor, officials say the eastbound roadway will be split and reconfigured to carry two-way traffic, with one lane provided in each direction.

What’s changing on Nebraska Ave NW

According to DDOT’s public notice and the District’s AlertDC advisory, the key commuter changes during the July 7–Aug. 7 window are:

• Westbound: two lanes closed on Nebraska Avenue NW between Nevada Avenue NW and Connecticut Avenue NW.
• Eastbound: roadway split and reconfigured for two-way traffic with one lane each direction.
• Traffic control: DDOT says signage and traffic-control devices will guide motorists and pedestrians through the work zone.

When it affects commutes

The closure is scheduled to run starting July 7, 2026 and continue through Aug. 7, 2026 (about a month), with the lane closures operating around the clock.

Resident guidance: how to drive through it

What’s changing on Nebraska Ave NW

• Westbound: two lanes will be closed within the project limits (Nevada Ave NW to Connecticut Ave NW).
• Eastbound/right-of-way: the roadway will be split and reconfigured to move two-way traffic through the zone (one lane each direction).
• Timing: the closures are planned as 24-hour work over the July 7–Aug. 7 window.

WTOP notes the work could create a traffic bottleneck on the area’s east-west commuter route over the month.

Who is most affected

This is the portion of Nebraska Ave NW that links drivers moving through the corridor near Chevy Chase. Impacts are most likely for:

• Commuters trying to cross the corridor during rush hours
• Residents seeking to access local streets and driveways near the work segment
• Pedestrians navigating around the construction footprint, signage, and traffic-control devices

How to plan during the closure window

• Allow extra travel time if your route uses Nebraska Ave NW through the work zone.
• Follow posted detour and traffic-control instructions and drive/turn carefully where cones, barriers, and signs guide traffic.
• Re-check plans before you go—the traffic pattern is expected to remain altered through the full July 7–Aug. 7 period.
