A12 Wellington Bridge Steel Beam and Concrete Repairs (ASF South)
The repair and refurbishment of Wellington Bridge, which carries the B1137 over the A12 between junction 20A and 20B near Hatfield Peverel, Essex.
Two recent bridge strikes had caused damage to the bridge steel girders and reinforced concrete deck. In addition to the repairs, maintenance work was carried out to the bridge and carriageway, which included work on expansion joints, painting and resurfacing.
The impacts had caused distortion to three of the beams, and these were returned to their correct geometrical shape by heat straightening. Trials were undertaken in-situ to ascertain the required heating patterns. Extensive surveys, geometric surveys plus the advice of Geoff Booth, a heat straightening expert were utilized to successfully complete the repairs.
