CONTRACTORS IN Glasgow were this week gearing up for a tricky bridge repositioning operation after replacing bearings on one of the approach viaducts to the M8 Kingston Bridge.
Main contractor Graham Construction will carry out a detailed survey of the strengthened deck's final geometry before repositioning it on the new bearings next week.
The central 150m insitu concrete section of the Stobcross on-ramp spans the M8 close to the Kingston Bridge, which has undergone a marathon 10 year strengthening exercise.
Recently, post tensioning subcontractor VSL Systems (UK) successfully added extra prestress to the tightly curved post tensioned deck box via external tendons (NCE 18 August).
This exercise took place while the deck was jacked up off its bearings and after new column heads had been constructed.
