The A6 Broughton Bypass eases congestion in Broughton Village, which had over twenty thousand vehicles passing through it every day. HOCHTIEF delivered two kilometres of new road and five junction improvements, including building a roundabout within the live carriageway and a new junction joining the M55 Junction 1 eastbound slip road.
- 2km of new road
- 5 junction improvements
- 2.5km footways
- Retaining wall in a watercourse
- 8km kerbing
- Street lighting
- 10km drainage
- Traffic signals
- Site clearance (150km²; 50,000m² within an ecological zone)
As minimising the impact of the works on the local community was a significant objective for Lincolnshire County Council, HOCHTIEF developed solutions which limited disruption while reducing the programme and cost. By redesigning the Brooklands Bridge foundations using a CFA pile design, we saved £3 million and removed 16 weeks from the critical path. We also saved £85k by proposing an alternative pavement design using cement bound granular mixtures (CBGM) B C16/20 rather than costly High-Density Macadam.
We closely supported LCC’s commitment to answering public queries and met regularly with the Broughton Bypass Review Group. Positive stakeholder relationships led to practical solutions, such as enabling us to arrange alternative parking with the local hotel while we built a new car park, allowing us to access a larger portion of the new site, which reduced the build time.
We completed the bypass on time and budget and achieved a Considerate Constructors Performance Beyond Compliance award.
