Week of October 21, 2019

The development team would like to acknowledge recent community feedback regarding noise along Wisconsin Avenue caused by vehicular traffic driving over temporary steel road plates, and that they are working with contractors to minimize this noise. These road plates are only temporary and will be removed following necessary underground utility work. The underground utility work along Wisconsin Avenue continues during nighttime hours and is anticipated to be completed in November.

Underground utility work along Woodmont Avenue, which began in March of this year, is expected to be finished in October. Most of this work is currently being performed during daytime hours. Following the completion of this work, the section of Woodmont Avenue adjacent to the construction site will be patched and restriped. Related road restoration work is being performed during daytime hours. A timeline for each phase of the underground utility work is estimated in this site plan.

Meanwhile, concrete pouring operations continue along Wisconsin Avenue. This week concrete placements are scheduled for Monday, Tuesday, Wednesday, and Friday mornings beginning at 5:30 a.m.

WSSC will temporarily shut off water service near the development site to accommodate the installation of water, sanitary and stormwater lines. The development team will issue an alert as soon as these dates are scheduled in coordination with WSSC. In the near future, there will be work related to Pepco’s infrastructure along Norfolk Avenue, just west of Wisconsin Avenue, which will be coordinated with the traffic control plan. Please stay tuned for more information.

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.



Monthly 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.

You are invited to attend the next update on Tuesday, December 3 at 6:00 p.m.
