THE eastbound lane of the M4 between Junctions 15 and 16 will be closed overnight tonight and on Friday night from 8pm to 6am.

This is being done to remove traffic management for the construction work on the Wichelstowe Southern Access underpass, including removing the temporary 50mph speed limit and returning the narrowed lanes to their original alignment.
