Development Update: Week of Mar. 18, 2019

Week of March 18, 2019:

In an effort to address some concerns about disruption and inconvenience associated with this project, which has been the result of the installation of utilities along Woodmont Avenue, the development team is exploring options to adjust the sequencing of this work to minimize the impact on neighboring residents and businesses, as well as commuters passing through the area.

The proposed revised schedule for construction activities associated with this work will be Monday through Thursday, beginning with the setting up of traffic control operations at 6 a.m. and work occurring between 7 a.m. and 7 p.m., with a reduction in activities during lunchtime (approximately 11:30 a.m. to 1 p.m). While it is anticipated that the majority of the work will be performed during these hours, there may be times that certain portions of the work will need to be done during nighttime hours. In the case of inclement weather, work may be made up on Friday, Saturday or Sunday. During this time, two-way traffic will be maintained with temporary steel road plates in use as needed. This proposed construction schedule is pending approval but is anticipated to go into effect the week of March 25, 2019.

Meanwhile, mass excavation and hauling continue at the construction site. In the coming weeks, daytime traffic along Woodmont Avenue is expected to lessen as the ramp into the construction site is relocated from Woodmont Avenue to Wisconsin Avenue. Throughout this time, the approved Montgomery County and State Highway traffic control plans will ensure minimal impact to traffic flow around the site. Our number one priority is the safety and security of pedestrians and commuters in and around the construction site. Concrete pouring operations will likely commence in May.


Sidewalk closures remain in place along sections of Woodmont, Norfolk and Wisconsin Avenues (view map of closures here), and additional temporary closures may be necessary during this time. Pedestrians will be detoured to the east sidewalk of Wisconsin Avenue during work hours and should take advantage of nearby crosswalks as needed. Please be vigilant and pay close attention to signage as detours may change occasionally.

The timeline for all upcoming phases of work is estimated in this site plan, including future phases along Wisconsin and Norfolk Avenues. Please note, this plan does not include anticipated work performed by Pepco.



Monthly construction updates

The developers and general contractor are committed to an open dialog with the community and they hold bimonthly construction updates for 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 County Regional Services Center, on the second floor in rooms A and B, located at 4805 Edgemoor Lane, Bethesda, MD 20814.

The next update will take place on Tuesday, April 2 at 6:00 p.m.
