A505 Baldock By Pass – This twin bore tunnel was constructed on a fairly steep incline, and had two changes of direction within its length.  The wall forms were designed and supplied by Special Formwork  who also manufactured the curved forms for the semicircular soffit.  The soffit forms sat on a mobile gantry designed and supplied by RMD Kwikform using proprietary equipment.  The main contractor was Norwest Holst Ltd and Boretech Ltd were concrete and steelfixing subcontractors.
