New bridge for M4 motorway
A new bridge will be lifted into place on the M4 in Wiltshire, closing the motorway overnight on Saturday.
The bridge is being placed at South Leaze near Swindon between junctions 15 and 16. The motorway will be closed in both directions and traffic diverted.
The closure will start from 1900 BST on Saturday and the M4 is due to re-open by 1000 BST on Sunday.

Another new bridge will be installed at junction 16 between 1900 BST on 30 May and 1000 BST on 31 May.

Dave Frampton, of the Highways Agency, said: "The new bridge replaces previous structures built in the early 1970s which had reached the end of their working lives."
