Beginning Monday, November 15, the NPS will begin the first phase of a seven-phase, 18-month project to repair and reconstruct various portions of the Rock Creek and Potomac Parkway from P Street, N.W. to Calvert St. N.W., including portions of Cathedral Ave.
During this phase, construction crews will close 1) the northbound lane of Shoreham Drive from Cathedral Avenue, NW, to Calvert Street, NW, and 2) the southbound lane of Cathedral Avenue from south of Woodley Road, NW to Shoreham Drive, NW.
This work will affect traffic patterns. For AM rush hour, traffic will be able to enter Shoreham Drive from Calvert Street, NW. and proceed to Rock Creek and Potomac Parkway. During all other times, including PM rush hour, traffic will be able to proceed northbound only on Shoreham Drive to Calvert Street, NW. There will be no entry to southbound Shoreham Drive and the Rock Creek and Potomac Parkway from Calvert Street, NW except during morning rush hour.
