Development Update: Week of June 24, 2019

June 21st, 2019

Marriott International Headquarters

Week of June 24, 2019:

This weekend, the installation of two tower cranes will begin at 3 a.m. on Saturday, June 22, and continue through Sunday. During this operation, southbound vehicular and pedestrian traffic patterns along Wisconsin Avenue will be redirected around the project site. These paths of travel will be closely monitored and carefully controlled by the general contractor in accordance with the approved traffic control plans. 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.

Meanwhile, concrete operations and other activities on the construction site are increasing and anticipated to continue for the next several months. As these activities ramp up, this will likely require limited detours of pedestrian access along Woodmont Avenue. The final push for mass excavation and hauling operations along Wisconsin Avenue is underway to ensure these activities can be completed in July.

Underground utility improvements and restoration work also continue along Woodmont Avenue. The majority of this work will be completed in July, followed by the next phase of work along Norfolk Avenue toward Wisconsin Avenue. This work will be performed primarily during nighttime hours to minimize impact to the neighboring businesses, traffic patterns, and pedestrian access, with occasional daytime work as necessary.

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).
