The
A45 is a major
road in
England. It runs east from
Birmingham past the
National Exhibition Centre and the
M42, then bypasses
Coventry and
Rugby, where it briefly merges with the
M45 until it continues to
Daventry. It then heads to
Northampton and
Wellingborough before running north of
Rushden and
Higham Ferrers and terminating at its junction with the
A14 road near
Thrapston.
The road used to run to
Felixstowe but most of the route was re-designated as the
A14 in the mid-1990s.
Birmingham to Coventry The former route of the A45 through Coventry exits at a junction as the A4114, in the part of Coventry called
Allesley, the western end of the Coventry bypass. At the staggered junction with the B4101, there is the factory of
Massey Ferguson, now owned by
TRW, and a
Sainsburys supermarket in Tile Hill. The road passes over the
West Coast Main Line, then enters Canley near a roundabout which is the main exit for the
University of Warwick. There is a traffic-light junction with the
A429, heading to
Kenilworth. There is a roundabout with the B4113, then a GSJ with the
A46 and A45. This busy section has many
speed cameras and overlaps with the A46. The next roundabout near Tollbar End, called the Tollbar Island, is one of the busiest in the Midlands. It has exits for the A46 north/Coventry Eastern Bypass,
Coventry Airport, and B4110, the former route of the A45. There are plans to build a GSJ here - the A45 will go under the other roads.
Where the road crosses the
River Avon, the road re-enters
Warwickshire. The A423 exits to the south-east at a GSJ near the UK factory of
Peugeot. The main road from
Warwick, the A445, meets near
Ryton-on-Dunsmore at traffic lights. This section has many speed cameras. Further east, there is a roundabout with the B4455, the
Fosse Way. There is a
grade separated junction ("GSJ") with the main road for
Rugby, the A4071, and the B4453. There is a
Texaco garage here. The next roundabout near
Thurlaston used to be very busy before 1972, when the
M6 opened. It is now the start of the
M45. The former A45 passes through
Dunchurch as the B4429. A junction was built on the M45 in 1991 to allow traffic to head south-east onto the A45, and to alleviate traffic congestion in Dunchurch.
Coventry to Dunchurch Heading towards
Daventry, the road is fairly wide and single-carriageway. The road passes a
prison at
Rye Hill and a
Young Offender Institution next to it at
Onley. After
Willoughby, the road enters
Northamptonshire, where it crosses the
Oxford Canal and
Grand Union Canal near
Braunston. The
Jurassic Way crosses the road here. The road enters Daventry, home to large distribution centres for
Ford Motor Company,
Tesco and
Diageo. The road briefly runs concurrent with the
A425 heading to
Leamington Spa, then heads south-east on the Daventry bypass, called the
Stefen Way. The road meets the B4038 at a roundabout where the A425 exits. The road heads west past
Dodford to
Weedon Bec, where it crosses the West Coast Main Line and Grand Union Canal, then meets the
A5 at traffic lights. The road passes through
Flore, then meets the
M1 at junction 16.
Dunchurch to M1 at Northampton Until 2004, the route of the A45 headed east along the dual-carriageway from junction 16 towards Northampton, but now it has been diverted to follow the M1 south, then to join with the route of the
A508 north from junction 15, to join the main flow of traffic on the Northampton bypass. Although slightly longer this route involves fewer roundabouts. From the point as which it meets the old route at the A45/A508 GSJ, near
Northampton High School, it crosses the
River Nene and
Nene Way, then there is a large GSJ with the
A428. This section is the Nene Valley Way, and overlaps with the
A43, which exits at a GSJ near
Weston Favell. The GSJ with the A5076 is also the exit for
Billing Aquadrome.
The former route of the A45 to Wellingborough is now the
A4500. The road has a GSJ with the B573 near
Earls Barton, which has a famous
Saxon church. The road meets the
Wellingborough bypass (A509) at a roundabout. It runs concurrently with the A509 to the GSJ near the bridge over the River Nene, where the A509 exits south near
Irchester Country Park.
East of Wellingborough, the road crosses the
Midland Main Line. There is a GSJ for the
A5001, which heads to
Rushden. There is then a roundabout with the A5028. This is the point where the new road (post-
A14), heads north-east rather than due east. The old route, now the B6
45, heads through
Higham Ferrers, which is now bypassed by the A45. The bypass runs alongside the
River Nene. At the roundabout with the
A6 near
Irthlingborough, it starts the follow the former route of the A605. The section of dual carriageway from the M1 now ends at the next roundabout. This is the start of the
Raunds bypass. The next roundabout is with the B663. The route bypasses
Ringstead and the A45 finishes at a GSJ with the A14 near
Thrapston.
Annexed section The original (1923) route of the A45 was Birmingham to Ipswich. The road was extended to Felixstowe in 1935, replacing the A139.
When the new A14 A1-M1 link road was opened to traffic in the mid-1990s, the Cambridge to Felixstowe stretch of the A45 was redesignated as the A14; from the former A605 to the A1 it was downgraded to B645; and from the A1 to Cambridge it became part of an extended A428.
