Fort Road and Rail Bridges carried a side road and redundant railway to Catterick Garrison over the A1. Successive weekend closures each of 34 hours duration were required to the main A1 carriageway. A 500 Tonne crane was situated adjacent to the bridge and used to lift the 2 sections of the railway bridge onto road transport as these were to be re-used by a Heritage Rail Company. Each piece weighed 47 Tonnes. The road bridge had the concrete deck broken out and the steel beams removed. The debris was cleared and the main carriageway swept and reopened. The following weekend the A1 was closed again and the north and south abutments were broken out using 8no. excavators and breakers varying in size from 50 Tonne to 21 Tonne. 1200 Tonnes of debris was removed from site for reprocessing and reuse in the new works.

Kneeton Manor Accommodation Bridge consisted of a single carriageway 4 span concrete bridge carrying a private access road over the A1. The demolition works were undertaken during a 16 hour A1 closure between 20:00 hours Saturday to 12:00 hours Sunday. 5no excavators and heavy breakers were used to break out the bridge deck, concrete beams and piers. During demolition an asbestos cement pipe encased in the concrete deck needed carefully removing before demolition work could continue. All material was removed from site on road wagons for reprocessing off site. The demolition and debris removal was achieved within the planned closure period and the A1 reopened on time.
Following the reconstruction of Brompton North, South and Catterick Railway Bridges (Phase 1), all traffic was diverted onto the new bridge decks which enabled the remaining old north bound decks to be demolished. As the A1 traffic was now partially on the new construction this gave us increased working space, this permitted working during daytime with no requirement for main carriageway closures. There were residential properties within 50 metres of the site requiring timed execution of noisy activities.

Tunstall Road and Manor Farm Bridges carried side roads over the main A1 carriageway. Demolition required the breakout of the concrete deck, removal of steel beams and total removal of the abutments. Main carriageway closures were not required as the A1 had been diverted onto the new construction some 200 metres to the west of the old A1. The concrete decks were broken out using 50 Tonne excavators and heavy breakers, the steel beams were removed and cut up to be reprocessed and the abutments broken out to the required level. All material was crushed for reuse.
