I see that the roundabout at M1 junction 10A is going to be removed next year and replaced with a radical new road layout which will mean a new route to the M1 for car travelling from Luton town centre and Harpenden and from Luton to Harpenden direct. Cars heading between the M1 and the Airport will have nothing to slow them down as the roundabout will be replaced by an additional length of duel carriageway that will cross the former roundabout.
