This is one version of the Jubilee Quietway in Westminster. It can only be implemented after CrossRail moves out of Hanover Square in 2018. It includes contraflow cycling in Holles Street and Harewood Place and the north end of Harley Street.
The northbound route uses Wimpole Street, as shown on the map. The southbound route uses Harley Street, as shown on the map for the version via New Bond Street.
