IN SERVICE MONITORING OF A38 MOTORWAY OVERBRIDGE, BRISTOL

This bridge is a 3 span continuous reinforced concrete deck of varying thickness both transversely and longitudinally with an 8 degree skew, supported on rubber strip bearings at the abutments and 2 intermediate piers. Built in 1966 its form is similar to many structures over the M4 in this area. The assessment of the bridge highlighted significant inadequacies. Various options were considered before equipment was installed to monitor the performance of the bridge in service. The paper describes the steps taken in this process and the results to date, together with advice for those pursuing this path in the future. (A) For the covering abstract see IRRD 882313.
