Development Update: Week of August 5, 2019

August 5th, 2019

Marriott International Headquarters

Week of August 5, 2019:

Underground utility work along Woodmont Avenue continues while related work along Norfolk Avenue is nearing completion. This week, underground utility work is expected to begin along Wisconsin Avenue, occurring primarily during nighttime hours to ensure traffic runs smoothly during the day, and is anticipated to continue through November of this year. Meanwhile, the final phase of mass excavation and hauling operations along Wisconsin Avenue is nearly complete, with most excavation equipment removed from the project site. Material deliveries are increasing as concrete operations are in full-swing and will continue through 2020.

Throughout this project, the approved Montgomery County and State Highway traffic control plans will ensure minimal impact to traffic flow around the construction site. At all times, two-way traffic will be maintained as reasonably as possible. The timeline for all upcoming phases of the utility work is estimated in this site plan. Please note, this plan does not include anticipated work performed by Pepco.

Meanwhile, sidewalk closures remain in place along sections of Woodmont, Norfolk and Wisconsin Avenues (view map of closures here). During this time, please be vigilant and pay close attention to detour signs and flagging operators as they direct traffic to minimize disruptions. Our number one priority is the safety and security of commuters and pedestrians around the construction site.
