1. Conversion of an existing hard shoulder as a running lane,
to provide additional capacity.
2. An alternative to road widening that provides:
• similar capacity and throughput
• greater trip time reliability
� no loss of safety
� the ability to remotely close lane(s), when needed
� construction and operational cost savings
� environmental benefits (air quality; noise)
� significantly faster deployment (no need for land take)
What is Hard Shoulder Running (HSR)?

• Introduced in 1995, near
London Heathrow airport
• Opened in 2006 – used to
prove the concept of hard
shoulder use
• Rollout began in 2009: 7 locations
now operational
• First scheme opened 2014. 10
locations now operational, +25 in
