New traffic pattern for Columbia Pike west end

There is a new traffic pattern along the west end of Columbia Pike that is expected to cause additional delays for those travelling through this area. This change is necessary so the project contractor can install a utility duct bank system beneath the eastbound lanes.

The following changes are in place between South Jefferson Street and the Four Mile Run bridge:

Only one lane is open in each direction of Columbia Pike daily, including weekends. An additional lane is open in the eastbound direction during weekday morning rush hours (7 am to 9:30 am).
There are new “no left turn” signs between South Greenbrier Street and South Dinwiddie Street, to help keep traffic and pedestrians moving safely during construction.

Thanks for your patience during construction. Businesses along this section of Columbia Pike are still open – please support them!

Construction Updates

Upcoming work and expected impacts

The Two-Week Construction Update describes construction activities planned for Monday, April 6 through Sunday, April 19 and their expected impacts.

Work on the temporary traffic signal at the Columbia Pike and South Frederick Street intersection has been delayed. The signal is planned to be operational in April.
Driveways on the south side of Columbia Pike between South Greenbrier Street and South Dinwiddie/Columbus Streets will be partially closed during work hours and overnight, as needed, to facilitate construction and concrete curing.
- Flaggers will be deployed to maintain access to the driveways during work hours. Half of an impacted driveway will stay open after work hours for property access.

Relocated bus stops

Bus stops will be temporarily moved during construction for this project and the Transit Stations project. See a list of current and planned relocations

Location

Columbia Pike from the Arlington/Fairfax County line to Four Mile Run (aka, the west end)

Status

Construction

Fort Myer Construction, the County’s contractor for this project, received its Notice to Proceed on Feb. 20, 2018. Crews began construction on the undergrounding phase first, moving in a west (South Jefferson Street) to east (Four Mile Run Bridge) direction.

Total project construction, including utility undergrounding and street improvements, is expected to last approximately three years, until early 2021.

Fort Myer will continue performing intermittent night work along Columbia Pike, as needed, when work is being performed at intersections. Nighttime work hours will be 9 pm to 7 am, Monday through Friday. Noise impacts will include back-up alerts from construction vehicles and noise from heavy vehicles and equipment (i.e. loaders, excavators, compressors, dump trucks, etc.).

The speed limit in the work zone has been reduced to 25 mph. This change will be in place through the remainder of project construction.

About the Project

This work is part of the Columbia Pike multimodal project that will make Columbia Pike a safer, more accessible route for all users. Arlington is transforming this main thoroughfare into a complete street that balances all modes of travel and supports high-quality, high-frequency transit service.

In addition to visible improvements to the road, extensive work will occur below the roadway – to replace aging and leak-prone water and sewer pipes and to bury existing overhead utilities underground.

Public Process

This open house provided information on two Columbia Pike projects that had entered new phases of construction: Multimodal and Transit Stations.
