An eighty-eight million pound scheme to ease congestion on the M4 the other side of Bristol gets underway today.

There'll be overnight closures and lower speed limits between junctions 19 and 22 - but the hard shoulder will be open as an extra lane there and on the M5 between J-15 and 17.

If you're likely to be heading up that way after ten P-M you're advised to allow extra time.
