A46 Newark to Widemerpool Improvements, Farndon Underpass, Newark

At the northern end of the road, an underpass provides a pedestrian link between the village of Farndon and Newark. To allow the maintenance of maximum traffic flow during construction, ABM’s sectional Portal Frame System was installed in three phases.
