The Klingle Valley Trail will be constructed along the closed section of Klingle Road NW from just east of Cortland Place to one block west of Porter Street. The trail will continue along the Ramp to Beach Drive and will connect to the Rock Creek Park Multi-Use Trail. The project falls within the Cleveland Park, Woodley Park, and Mount Pleasant neighborhoods. 


Construction started in July 2015. The project is scheduled to be completed in the Spring of 2017.
