Traffic advisory

August 12, 2022

National Capital Region—The northbound lane on Colonel By Drive, between Avenue Road and Mount Pleasant Avenue, will be closed from Monday, August 15, to mid-October. This closure will be in effect on weekdays, from 6:30 am to 5:30 pm. Users should expect delays during this time.

Outside closure hours, both lanes will be fully open and operational.

The closure is to allow rehabilitation work on the Colonel By Drive retaining wall. This work is necessary, as some portions have been damaged over the years from snow and road salt. We will be removing the existing retaining wall and replacing it with a new one.

During the work, flag persons will be on-site to direct users. The National Capital Commission urges users to exercise caution, respect working crews and equipment, and obey signage and flag persons on-site.
