About the project

Type of application: Highways

The project comprises the improvement of the A66 between the M6 at Penrith and the A1(M) at Scotch Corner. The existing route is 80km in length and intermittently dualled with approximately 30km of single carriageway, within six separate sections. The scheme comprises upgrades to the existing single carriageway sections of the road to dual carriageway. The scheme also includes junction improvements, minor improvements to the existing dual carriageway sections of the A66. On completion, the project will result in an 80km route with two lanes in both directions. This will improve journey time, safety and connectivity.

The Examining Authority will ask questions about the proposed development. The applicant and anyone who has registered to have their say can get involved and submit comments at each deadline in the timetable. You can also attend hearings that may take place. This stage takes up to 6 months.

What happens at the examination stage?

The Examining Authority writes its recommendation report. This must be completed and sent to the relevant Secretary of State within 3 months of the end of examination stage.

Making a recommendation.
