The curved One Tysons East project has hit a roadblock that could stall the project.

Akridge — the project’s developer — has put a temporary hold on the entitlement process for the office building while it works out right-of-way negotiations with the Virginia Department of Transportation over the Route 123 frontage, according to the Washington Business Journal.

Leadership at Akridge said the process should only take a couple of months, but in the meantime, the Business Journal says the project is classified by Fairfax County as “indefinitely deferred.”

The last major change for the project was in April when the building went through a series of design changes, including an effort to mitigate the likelihood of bird impacts with the building.

The project is part of a series of new buildings planned for Tysons East — a neighborhood around the McLean Metro station seeing rapid growth spurred in part by the opening of the new Capital One headquarters.
