Just got this roadworks warning courtesy of the VBOA for anyone attending the Open Day

Dear All,
If you would normally use the Junction 10 exit from the M1 (Luton Airport) to reach the Heritage Centre, then ongoing road works will require you to take a different route at the roundabout at the end of the motorway spur road (Junction 10A)
Do not take the usual second exit at the roundabout (Airport Way) but instead take the first exit towards Luton town centre. Then first right at the lights into Cutenhoe Road. Down to the bottom of the hill (speed bumps all the way down) and then left at the bottom into Park Street, and the Heritage Centre car park entrance is 250 yards along on the right.
