NOTE: The speed flow, overhead sign messages or other information shown on our live traffic speed flow map is updated every few minutes. We cross check the data and aim to provide warnings if there could be a delay or an inaccurate speed reading. There can be occasions, beyond our control, and despite our best efforts where the speed flow could be inaccurate. We cannot therefore guarantee the speed you can expect on any stretch of the motorway is always accurately shown. However we hope you will find our live traffic speed flow map a useful tool in trying to plan your journey. Safe driving.

Traffic drops by a fifth past the junction
| Stretch | All vehicles a day | Lorries | Miles |
|---|---|---|---|
| J18 to J19 (south of the junction) | 110,877 | 19,440 — 17.5% | 3.3 |
| J19 to J20 (north of the junction) | 88,994 | 12,322 — 13.8% | 3.5 |
The stretch north of the junction carries 21,883 fewer vehicles a day, about a fifth less. That is a net figure — traffic joins here as well as leaves — but it is consistent with a large share of the M1’s traffic south of Catthorpe heading for the M6 and the A14. The lorry share tells the same story: 17.5% south of the junction, the 3rd highest on the M1, against 13.8% north of it. J18 to J19 combines two count points either side of a local-authority boundary that report the same measurement, published once.
Rebuilt from 2014 to 2016
The interchange was rebuilt between 2014 and 2016. Work ran from 06/01/2014 to 22/12/2016 at a cost of £191 million, the Highways England figure. A figure published in December 2019 put more than 157,000 vehicles a day through the interchange.
Two movements you cannot make
There is no link from the A14 to the M1 southbound, and none from the M1 northbound onto the A14. If either is your route, plan it before you set off rather than at the junction.
The M6 towards Birmingham
Spaghetti Junction is about 29 miles along the M6 from here. Our sister site M6 Traffic carries the news for the whole M6. Before the M6 existed, the route west was the M45 at junction 17, two junctions south.
The A14 towards the A1
The A14 is one of the main crossings between the M1 and the A1: it meets the plain A1 at Brampton, near Huntingdon. The full list is on our M1 and A1 link roads page; for news on the A14 itself, see Traffic News England.
