Connecticut Avenue NW Reversible Lane Safety and Operations Study Environmental Conditions Inventory Report

Connecticut Avenue NW is a six-lane roadway in NW Washington DC. Prior to the COVID-19 Pandemic, from 7:00-9:30 AM and 4:00-6:30 PM, a two-lane reversible lane system operated along Connecticut Avenue NW. This system extended for approximately 2.7 miles through the neighborhoods of Chevy Chase, Cleveland Park, and Woodley Park, to manage the utilization of the six travel lanes. The reversible system operated as four southbound lanes in the morning peak period and four northbound lanes during the afternoon peak period, with the two middle lanes reversing during these peak periods. Poll-mounted dynamic and static signing adjacent to the outside lanes provided instruction to motorists on how to utilize the reversible lane system and the correct lanes of travel when in operation. During peak periods, parking and commercial loading is prohibited; however, bus stops remain in service. Prior to the Pandemic, during non-peak periods, Connecticut Avenue NW operated with two travel lanes in each direction with the outside lane allocated for bus stops, parking, and commercial loading.
