a roundabout created when the road was built from Towcester in 1991. This roundabout was dangerously unsuited to the traffic volumes but was upgraded with traffic light controls during the first half of 2015. A flyover may need to be installed when the expansion of Towcester begins in 2018–2022. Continuing towards Northampton, it by-passes Blisworth and Milton Malsor villages, before reaching the M1 at junction 15A, at Rothersthorpe services. This stretch has four dangerous crossover junctions - one from Towcester via Old Towcester Road, two from Tiffield and one from Blisworth, unlike the rest of the route from the M40 where the junctions are either fully graded, as at Silverstone, or have roundabouts. M1 to Corby From M1 junction 15a the A43 runs concurrently southbound on the M1 to junction 15. It then follows the A45 Nene Valley Way up to the Lumbertubs Way Interchange. From here it splits from the A45 and continues via dual carriageway where it meets the Round Spinney roundabout. North of Northampton, it rejoins the old course of the A43 and passes through Moulton. A new 1.6 km dual carriageway bypass is currently being constructed which will link the Round Spinney roundabout with the existing road just north of the Moulton roundabout, which is due for completion in Spring 2018. Following this, the road has a straight, rural stretch before reaching a roundabout at Broughton. After bypassing Broughton, it continues towards Kettering. It overlaps the A14 at its Junction 8, to bypass Kettering. At Junction 7 the A43 re-emerges on a new dual carriageway bypass. The old route of the A43 through Kettering town centre is still intact. After bypassing Kettering, the road previously travelled through the historic village of Geddington. The old road is still regularly used, possibly due to poor signage or lack of SatNav updates. A new bypass, called the Corby Link Road, opened in 2014, from Barford Bridge on the A6003 to the A43 west of Stanion. Continuing from here, it passes the Euro-Hub site at Corby, and then it passes Corby and reaches several roundabouts. Corby to Stamford After bypassing Corby and Weldon, it heads out on a rural stretch, past Deene Park, and then bypassing Bulwick, the only village on this stretch. It passes some splendid woodland, and then heads towards Duddington. Bypassing Duddington, it meets the A47. After it passes through Collyweston and Easton-on-the-Hill. Then it meets the
