Calderdale A629 Highway Development Scheme

Phase 1 of the Calderdale A629 Highway Development Schemeis a £22 million-pound venture that looks to reduce journey times, ease congestion, and enhance business access to the strategic road network.

Funded by the West Yorkshire Combined Authority (WYCA) for Calderdale Council (CMBC), the Calderdale A629 Highway Development Scheme Is a project comprised of a series of infrastructure improvements to the junctions and corridor of the A629.

Split into two parts, Phase 1a will act as an enabling element to the subsequent delivery of Phase 1b, covering adjacent sections of the A629. 

The key issues that led to the creation of the Calderdale A629 Highway Development Scheme consisted of problems such as; the scarce highway capacity in comparison to the increasing population and economic growth in the region, and its impact in delaying journeys amongst commuters traveling to work and emergency service response times. Additionally, the slow start and stop traffic causes environmental problems by deteriorating air quality within the area, particularly along Huddersfield Road where heavy vehicles must accelerate up steep inclines adding to the problems.

These aggregated matters contribute to the problems associated with the increasingly inefficient highway network, resulting in unreliable travel opportunities, presenting a barrier to economic growth and quality of life to residents of both Halifax and the wider region.

To solve these issues, a new signal controlled junction has been created to replace existing mini-roundabouts, with the A629 also being widened to continue the existing two lane provision northbound. Furthermore, a new highway link between the A629 and Stainland Road will be created, with a new roundabout at the Stainland Road junction to the western side of the new link formed.

Delivering Phase 1 will ease congestion and accessibility to and from Halifax and Huddersfield to support and increase local employment 

The project has witnessed challenges concerning the widening of the existing bridge. With constraints regarding the safety of barges in the canal below the bridge when attempting to widen it. Pell Frischmann have been able to review the highway model and look to find expert alternatives that will allow both safety and accessibility on and around the highway, mostly notably, the diverting of the road expansion to avoid the need to hinder canal access.

Additional challenges saw the buying of land to gain access for expansion, highlights the need to negotiate with current owners and complete thorough ground investigations to decontaminate the area. With Japanese knotweed also found within the area, cautious management would need to be undertaken to ensure successful clearing of the invasive species.

Delivering Phase 1 will ease congestion and accessibility to and from Halifax and Huddersfield to support and increase local employment in areas such as Copley, improve air quality around the area, and reduce levels of delays and queuing on the A629 through the Calder & Hebble junction.
