Development Update: Week of May 27, 2019

Marriott International Headquarters

Week of May 27, 2019:

Mass excavation and hauling operations continue along Wisconsin Avenue and are anticipated to conclude in mid July. Underground utility improvements and restoration work continue along Woodmont Avenue and are anticipated to conclude in late July. Work at the intersection of Woodmont and Norfolk Avenues is currently being completed during nighttime hours to minimize potential impact on neighboring businesses, traffic and pedestrians. Meanwhile, concrete operations are expected to begin in the next couple of weeks.

In June, two tower cranes will be installed at the construction site, which will take place on the weekends with traffic being detoured around the construction site along Wisconsin Avenue. Installation of the first crane is scheduled for Saturday, June 8. Installation of the second crane is anticipated to be June 22.

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.

Sidewalk closures remain in place along sections of Woodmont, Norfolk and Wisconsin Avenues (view map of closures here). As additional temporary closures may be necessary, pedestrians will be detoured to the east sidewalk of Wisconsin Avenue using nearby crosswalks as needed for their safety. Please be vigilant and pay close attention to signage for any detours that may be necessary. Our number one priority is the safety and security of pedestrians and commuters around the construction site.
