M1 MOTORWAY, WILSTHORPE LODGE BRIDGE

This paper describes the assessment of Wilsthorpe Lodge Bridge, a three span concrete overbridge spanning the M1 motorway. The findings of the inspection, including details of the observed defects, are presented and the methods adopted for the assessment are described. The Principal Inspection covered the visible parts of the structure only. The carriageway surfacing prevented inspection of the upper surface of the deck slab, however no reflective cracking was observed. The assessment indicated that the capacity of the cantilever slabs was inadequate. A Special Inspection was therefore initiated and on removal of the surfacing, transverse cracking of the reinforced concrete section was visible. The paper outlines the additional assessment work undertaken to develop solutions whereby the reduced capacity of the structure could be acceptable in the short term.
