Week of January 13, 2020

Along Wisconsin Avenue, large-scale concrete pouring operations will begin at 5:00 a.m. on Monday and Tuesday of this week. Utility work is also scheduled for this Monday and Tuesday during daytime hours only.

Beginning Wednesday and continuing through Thursday and Friday, nighttime work is scheduled to take place along Wisconsin Avenue to finalize the duct bank vaults in coordination with Pepco, with additional duct bank work taking place along Norfolk Avenue.

Along Woodmont Avenue, plans for a new traffic pattern are being finalized this week. Final utility installations are also being completed. By the end of this week, construction will be finished on a new, covered pedestrian walkway along the Woodmont Avenue side of the construction site.

Throughout this project, the approved Montgomery County and State Highway traffic and pedestrian control plans will ensure minimal impact to traffic flow around the construction site. Meanwhile, sidewalk closures remain in place along sections of Woodmont, Norfolk and Wisconsin Avenues (view map of closures here).

Our number one priority is the safety and security of commuters and pedestrians around the construction site. During this time, please be vigilant and pay close attention to detour signs and flagging operators as they direct traffic to minimize disruptions. Failure to follow these directions may risk your safety or even result in a citation from local law enforcement.


Bimonthly construction updates

The development team is committed to an open dialog with the community and holds bi-monthly construction updates open to the general public. These updates are generally scheduled for the first Tuesday of every other month and take place in downtown Bethesda at the Bethesda-Chevy Chase Regional Services Center located at 4805 Edgemoor Lane, Bethesda, MD 20814. The next construction update will be announced in early 2020.
