Northwick Park hospital and the University of Westminster Harrow campus are just across the border in Brent. Northwick Park roundabout was built during an era when cars were thought to be the future of transport. Walking and cycling links to the university and hospital are very poor, but there is plenty of scope for improvement without reducing capacity for motor vehicles.
Northwick Park Roundabout has multiple lanes and no signals, encouraging high vehicle speeds. The roads leading to the roundabout are dual carriageways only for short sections, so this extra road space does not create extra useful traffic capacity. There is currently a subway on the southern arm and an inconvenient two-stage toucan crossing on the western arm, but no pedestrian crossings of the other arms. We propose cycle lanes on all approach roads and signals on the roundabout.
Watford Road currently has slip roads leading to the hospital which encourage high speeds. Cyclists and pedestrians are squeezed into a narrow shared footway but there are 4 or 5 lanes for motor traffic. We propose removing one motor vehicle lane, tightening approach roads and providing zebra and cycle crossings across access roads.
