Work will start on demolishing the M56 Bowdon View Bridge on junction 7 in south Manchester this weekend.
The M56 motorway will be closed eastbound from its junction with the M6 at junction 9 and westbound from junction 6 at Hale Barns from 10pm on Friday 15 October until 5am on Monday 18 October, as demolition work is carried out on the bridge, linking junction 7 of the M56 and the A556.
A new £3.2m bridge has been constructed on a site alongside the motorway to replace the old bridge, which has become corroded.
A giant multi-wheeled vehicle will jack-up the 1,830 tonne, 74-metre-long bridge, carry it 500 metres along the M56, and slowly manoeuvre it into place over the motorway.
As the new bridge is moved into place the following weekend, the same closures will happen from 10pm on Friday 22 October until 5am on Monday 25 October.
The Highways Agency said the M56 junction 7 westbound exit slip road will remain closed to traffic throughout that week, reopening at 5am on Monday 25 October.
