March 22nd, 2019

Marriott International Headquarters

Week of March 25, 2019:

Beginning March 25, the development team is adjusting the Woodmont Avenue utility work schedule to minimize the impact on neighboring residents and businesses, as well as commuters passing through the area, in an effort to address some concerns about disruption and inconvenience. The development team and general contractor have visited neighboring properties to hear their feedback and discuss the construction timeline, and continue to make accommodations whenever possible.

The revised schedule for all noise-related construction activities will be Monday through Thursday, beginning with traffic control operations at 6 a.m. and work occurring between 7 a.m. and 6 p.m., along with brief, less-intrusive activities during lunchtime hours from approximately 11:30 a.m. to 1 p.m. While the main activities will occur during these hours, there will certain portions of the work will need to occur during the overnight hours from 6 p.m. to 5 a.m. In the case of inclement weather, work may take place Friday through Sunday.

Underground utility improvements and restoration work continue to move northbound along Woodmont Avenue toward Norfolk Avenue. This work, which includes stormwater, sanitary and domestic water lines, is anticipated to continue through July. During this time, two-way traffic will be maintained as often as possible with temporary steel road plates in use as needed. The timeline for all upcoming phases of this 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.

Beginning the first week of April, 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. Meanwhile, mass excavation and hauling continue at the construction site, with intermittent bedrock blasting, if required. This process is anticipated to continue through July. It is anticipated that concrete operations will begin 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. Our number one priority is the safety and security of pedestrians and commuters in and around the construction site.
