Coventry to Northampton
The journey begins on the A4600 Sky Blue Way in Coventry. Heading eastbound, the road intersects with the A444 and A4082 before crossing the A46 Eastern Bypass to enter Warwickshire. The route transitions from urban environments through the village of Binley Woods into more rural landscapes, where it meets the Fosse Way and crosses the River Avon at Bretford.
Approximately 3.8 miles (6.1 km) further, the road enters Rugby, passing Rugby School and intersecting with the A4071 and A426. After exiting the town via the suburb of Hillmorton, the road crosses the A5 near the Daventry International Rail Freight Terminal (DIRFT). It then reaches the original terminus of the M1 at junction 18, bypassing the towns of Crick and West Haddon, and passing the Althorp family estate before entering Northampton.

Northampton to Cambridge
Continuing east from Northampton, the A428 passes through Little Houghton, Brafield-on-the-Green, and Yardley Hastings. It then enters the City of Milton Keynes in Buckinghamshire, meeting the A509 at the Warrington roundabout. As the route progresses toward Bedford, it passes through Lavendon and Cold Brayfield.
Upon crossing the Great Ouse, the road enters Bedfordshire at Turvey and continues to Bromham, where it meets the A422. To avoid the center of Bedford, the road follows a new alignment—leaving behind the former eastbound route (now the A4280)—and crosses a new bridge over the Great Ouse to merge with the A421 south of Kempston.

The Transition and Final Stretch
At this point, the A428 loses its identity as the route continues as the A421, bypassing Bedford, Great Barford, and Roxton until it reaches the A1 at the Black Cat roundabout. The route regains its A428 designation after leaving the A1 via a grade-separated junction south of St Neots. After crossing the East Coast Main Line, it enters Cambridgeshire.
The final section follows the path of the former A45, which was redesignated as the A428 following the opening of the A14. It meets the A1198 (formerly the A14) at the Caxton Gibbet roundabout near Papworth Everard. The road then becomes a dual carriageway, bypassing a single carriageway section near Hardwick, before terminating at the Girton interchange. Here, it merges into the A14, connecting traffic from the M11 junction 14 and A14 junction 31.
