A box (bridge-like) structure will be built over the M42, just north of junction 9 to allow the HS2 railway line to travel over the motorway.
Traffic management will be in place during construction, some lane and overnight closures may be required. When closures are required you will be able to find further information via the Roadworks Finder.
These works are being carried out by HS2. For more information you can find contact details on the HS2 website.
