M56 Thorley Lane Scheme
Part of our programme of improvements (generally with value <£10m)
What is happening?
Works will be carried out to improve the load capacity of the bridge carrying Thorley Lane in Altrincham over the M56 near junction 5 the Manchester Airport exit. The existing bridge is to be demolished and a new bridge built in its place.
These works are part of the national Pinch Point Programme. The Pinch Point Programme forms part of the UK Government's growth initiative, outlined during the Chancellor’s Autumn Statement in November 2011.
When and where is this happening?
Thorley Lane Bridge is located over the M56 at junction 5 the exit for Manchester Airport.
The construction started in May 2014 and is estimated to last until March 2015. Preliminary work is taking place on Thorley Lane at the bridge deck level but this will not affect traffic at the motorway level.
Why is this happening and what will it cost?
The existing Thorley Lane Bridge has deteriorated over time and has been assessed as being too weak to carry road traffic to current standards. A weight limit has been imposed on the bridge which causes a restriction on the road network. The bridge must be demolished and reconstructed with a new stronger bridge in order to maintain a safe local route over the M56.
The estimated cost is £5.5 million.
How will the scheme be carried out?
The scheme will be carried out in phases to minimise disruption to residents, businesses and the travelling public.
- The existing bridge and the pier in the central reservation will be demolished.
- The central pier will be reconstructed and the bridge supports either side of the motorway will be rebuilt, whilst the motorway is open to traffic.
- The new bridge deck will be constructed.
- The site will be reinstated to fully re-open to traffic.
What are the benefits?
As part of the Pinch Point Programme, this scheme aims to:
- improve safety by removing the current weight restrictions on the road network in the area
- boost the economy by removing traffic diversions necessitated by the weak bridge

Will there be roadworks?
Yes, roadworks will be needed. Thorley Lane itself is now closed to through traffic and during the works there will be lane and hard shoulder closures on the M56.
How will you manage traffic?
Traffic on the M56 will be managed by a combination of lane closures and 50mph speed limit.
Will there be diversions?
Clearly signed diversion routes will be in place during the closures of both Thorley Lane and the M56 between junctions 5 and 6.
Diversion route level 1: Using the motorway network.
Motorists travelling towards Manchester along the M56 eastbound will be directed off the M56 at junction 9 on the M6 northbound, to junction 21A, and on the M62 eastbound to junction 12. Motorists traveling to north Manchester and the east can continue on the M60 northbound/clockwise. Motorists wishing to travel to Manchester can continue on the M602. Motorists wishing to travel to west, south and east Manchester can follow the M60 southbound.
Motorist travelling westbound on the M56 will be diverted on the M60 northbound/clockwise to junction 12, then westbound on the M62 to junction 10, and on the M6 southbound to junction 20 to re-join the M56.
Diversion route level 2: Alternative Route using A roads.
Motorists travelling towards Manchester along the M56 eastbound will be directed off at junction 7, and right at the roundabout onto Dunham Lane, Woodlands Road, Stockport Road, Shaftesbury Avenue and Altrincham Road to re-join the M56 at junction 3.
Motorist travelling from Manchester wishing to travel on the M56 westbound will be diverted onto the M56 eastbound to junction 3 and left onto Altrincham Road, Shaftesbury Avenue, Stockport Road, Woodlands Road and Dunham Lane to re-join the M56 at junction 8.
Diversion route level 3: A538 and Airport Traffic Only using the local road network.
Motorists travelling towards Manchester Airport along the M56 eastbound will be directed off at junction 6, under the motorway and left on to Runger Lane, which becomes Thorley Lane, and left on Outwood Lane West to the airport. Traffic travelling to Manchester will turn right on Outwood Lane West, round the roundabout and following the slip road back on to the M56 at junction 5.
Motorists travelling from Manchester along the M56 westbound will be directed off at junction 5, left at the next roundabout and left into Thorley Lane, which becomes Runger Lane, and back onto the M56 at junction 6.
