Southern Expansion: Road Closures
 

Update: May 18, 2023

On or about May 31, 2023, several traffic pattern changes and detours will take place on the roads surrounding the construction supporting Arlington National Cemetery’s Southern Expansion project.  The public can expect to see the following changes:

1. The southbound ramp on Washington Boulevard that connects drivers to westbound Columbia Pike will reopen

2. The southbound ramp on Washington Boulevard that connects drivers to eastbound Pentagon South Parking will be closed. Instead, eastbound Pentagon South Parking drivers will be detoured to use the westbound Columbia Pike exit and turn left at the modified intersection with the new temporary traffic signal.

3. Westbound Columbia Pike from South Pentagon Parking to the new temporary traffic signal will be reduced to one lane.  Eastbound Columbia Pike from the new temporary traffic signal to Pentagon South Parking will be reduced to one lane and traffic will be shifted to one of the former westbound lanes.  

4. These detours are expected to last until at least December 31, 2023. 


On or around April 17, 2023, several traffic pattern changes and detours will take place on the roads surrounding the construction supporting Arlington National Cemetery’s Southern Expansion project. The public can expect to see the following changes:

1. The southbound ramp on Washington Boulevard that connects drivers to eastbound Pentagon South Parking will be modified to intersect Columbia Pike with a new temporary traffic signal. This will allow both westbound and eastbound turns on Columbia Pike, as well as towards Pentagon South Parking.   

2. The southbound ramp on Washington Boulevard that connects drivers to westbound Columbia Pike will be closed. Westbound Columbia Pike drivers will be detoured to the Pentagon South Parking ramp, where the intersection was modified to allow westbound traffic.

3. These detours are expected to last until at least June 30, 2023.
