Rock Creek and Potomac Parkway: Introduction

Every weekday at 6:45 in the morning, four or five United States Park Police officers throttle up their motorcycles, drop into traffic on the Rock Creek and Potomac Parkway, and start placing barricades. By 9:30 a.m., the entire four-lane road has been reversed - what was northbound is southbound, what was southbound is closed. In the afternoon, between 3:45 and 6:30 p.m., they do it again in the other direction. The changeover takes thirty minutes from end to end, which means the parkway functions as a one-way commuter chute for only about two real hours each rush. The rest of the time it does what it was designed to do in 1923: carry cars slowly through a wooded river valley, framed by sculpture, parallel to a creek the rest of Washington forgot.

Rock Creek and Potomac Parkway: A Parkway, Not a Highway

The Rock Creek and Potomac Parkway, built between 1923 and 1936, was conceived in the era when Americans believed roads could be works of landscape art - winding, scenic, hostile to commerce. Trucks have never been allowed. Stone-faced bridges arch the cr...

Drivers entering during a changeover sometimes find themselves alone on four empty lanes wondering whether they have made a serious mistake. After t...

The Rock Creek Park Trail runs the full length, from the Lincoln Memorial to Connecticut Avenue, and continues north along Beach Drive. The Shoreline section along the Potomac, the oldest piece, predates 1967. T...

Rock Creek and Potomac Parkway: The Hidden Valley

Mon, 01 Jun 2026 00:00:00 GMT

Photo credit Famartin, CC BY-SA 4.0. From the air, the parkway and creek together carve a wooded green stripe right through the densely built capital - a vein of forest that runs from the Potomac up past the National Zoo and continues into Maryland. The contrast is the point. On either side stand embassies, the Nava...
