Week of November 18, 2019

Last Friday and Saturday, Norfolk Avenue at the intersection of Wisconsin Avenue was temporarily closed to all vehicular traffic to facilitate the installation of an electrical duct bank in cooperation with Pepco. This work will be completed today, Nov. 18, and Norfolk Avenue is anticipated to be repaved and striped tomorrow and reopen to traffic as soon as possible. Until then, traffic will be diverted around the work area, so please be vigilant and pay close attention to detour signs and flagging operators as they direct traffic to minimize disruptions.

Meanwhile, underground utility work along Woodmont Avenue, which began in March of this year, is now complete. Nearly all temporary steel road plates have been removed. The section of Woodmont Avenue adjacent to the construction site will soon be repaved and striped. This road restoration work is being performed only during daytime hours.

Only minor underground utility work is left to do along Wisconsin Avenue, including the installation of the final sanitation line to the development site. This work will soon be scheduled in cooperation with WSSC, and at that time, additional details will be shared regarding any noise, service disruptions, or lane closures that may be necessary related to this work.

At this time, large-scale concrete pouring operations continue along Wisconsin Avenue. In fact, the first-floor slab was poured on Friday. This week, a concrete placement is only scheduled for Friday, Nov. 22, beginning at 5:00 a.m. These concrete pouring operations will continue for several months, and will generally start early in the morning and continuing throughout the day.

Once the underground utility work along Norfolk and Wisconsin Avenues is completed, all work is anticipated to be contained within the site for the duration of construction. Each phase of the underground utility work is estimated in this site plan.

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). Based on recent community feedback, new and enhanced traffic and pedestrian control plans have been submitted for review. We anticipate these new plans will be approved and implemented in October.

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.
