Each hour is compared with that sensor’s own free-flow speed rather than the speed limit, because some sensors sit on bends and slip roads that never reach 70 mph. Quiet hours carrying under 600 vehicles are left out, so overnight roadworks are not mistaken for congestion.

Questions about the A45

Is the A45 closed right now?

4 closures were in force at our last check of the National Highways feed (1:38am today, UK time): 7.5t weight restriction; A45 southbound Queen Eleanor exit slip road lane closure; and Thrapston roundabout lane closure, plus 1 more. This covers planned roadworks and lane closures, not accidents.

Is the A45 closed tonight?

National Highways has 2 closures booked on the A45 in the next 24 hours, the first due from 8pm, so it may already be in place: A45 southbound Queen Eleanor exit slip road lane closure; and Lane closure including roundabout northbound. Plans can change on the night.

When will the roadworks on the A45 finish?

2 schemes lasting a week or more are listed. The first due to end is A45 lane closure eastbound (16 Nov 2026); the last is 7.5t weight restriction (31 Mar 2027). End dates are National Highways’ own schedule and can move.
