Development Update: Week of April 22, 2019

April 19th, 2019

Marriott International Headquarters

Week of April 22, 2019:

Mass excavation and hauling operations continue from Wisconsin Avenue. It is anticipated that these operations will continue through July with concrete operations beginning in mid-May. Throughout this project, the approved Montgomery County and State Highway traffic control plans will ensure minimal impact to traffic flow around the construction site.

Underground utility improvements and restoration work continues along Woodmont Avenue and will continue through July. As the work at the intersection of Woodmont and Norfolk Avenues is quite deep, this work will be completed during nighttime hours to minimize potential impact on traffic and pedestrians. At all times, two-way traffic will be maintained as often as possible.

The timeline for all upcoming phases of the utility work is estimated in the attached 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). Additional temporary closures will 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.
