Corridor Improvement Programme Phase 1

The Corridor Improvement Programme (CIP) is a programme of low and medium cost highway interventions on strategic highway corridors on the Key Route Network (KRN). CIP aims to deliver benefits for all road users with an emphasis on reducing journey times, in order to improve connectivity and accessibility to economic growth sites including those located in spatial priority areas.

The Headline objective for the CIP programme is:

“To reduce congestion on priority highway corridors/junctions on the West Yorkshire Key Route Network, such as A61, A62, and A647, by 2025, which is constraining growth associated with new housing and employment sites in the Spatial Priority Areas”

In order to achieve this objective the programme aims to deliver the following target outcomes:

  • 8% reduction in journey times (all traffic);
  • 12% reduction in journey times for buses; and
  • 7% increase in bus frequency.

Phase 1 comprises of numerous projects across the City Region to delivery junction improvements by 2021.
