Aces - What time does it open ?

Thinking of doing another time lapse piece Saturday morning, but I want to head down early to get a good run on the A406 ( and maybe a little excess speed )…

A little light says about 7am, is this still the case ?

Clocked it last night and it was 23 miles in 30 minutes ( commuter traffic ) , so early in the morning I’m thinking I could fly it on down without the bottle necks at Enfield etc etc .
