The A28 is a modern dual carriageway with speed limits at 130 km/h, dropping to 110 km/h in rain. Between Rouen and Abbeville, expect tolls: roughly €10 for a standard car. From Abbeville to the Belgian border, the A16 is toll-free. Fuel stations are plentiful every 30 km, but prices near the border tend to be higher. Fill up in France when possible.

• Fuel: Rouen area (€1.80/L), Abbeville (€1.75/L), border (€1.85/L)
• Tolls: A28 Rouen-Abbeville €10.10, then free
• Rest areas: Every 20-30 km with toilets and vending machines

The route's infrastructure is excellent. Road quality is uniform on motorways, but the final approach to Knokke-Heist on Belgian N49 can have rough patches. Winter driving rarely requires snow tires, but fog near the coast is common.

For budget-conscious travelers, using a fuel card or avoiding A28 tolls via the D915 from Rouen to Neufchâtel-en-Bray saves money but adds 30 minutes.

Between Rouen and Abbeville, the A28 cuts through the rolling Pays de Caux, a plateau of arable land punctuated by deep valleys. At Saint-Valery-sur-Somme, a detour onto the D940 offers views of the Baie de Somme, a UNESCO-listed estuary. The bay is famous for its seals and migratory birds.

• Seal colony at Le Crotoy: best early morning
• Hike the GR120 trail along the cliffs
• Local cheese: Neufchâtel (from the village of the same name)

Further north, the A16 passes through the flat landscapes of French Flanders, where hop fields and brick farms dominate. Near Dunkirk, the coastal dunes of Malo-les-Bains offer a contrast. Local commerce thrives in the markets of Bergues (Saturdays) and Hondschoote, where you can buy Potjevleesch, a terrine.

The natural landscapes are intimately tied to local commerce: cider in Normandy, beers in Flanders, and seafood at every coastal stop.

Safety on this route is high. Motorways are well-lit with emergency phones every 2 km. On the A16 near the border, watch for sudden fog banks. The approach to Knokke-Heist involves roundabouts and local roads; reduce speed accordingly.

• Emergency number: 112
• Service stations: Aire de Poix-de-Picardie has playground and clean toilets
• Parking at Knokke: paid zones in center, free at the station

Family suitability is high. The Baie de Somme offers mini-trains and puppet shows for children. Parc du Marquenterre bird reserve has elevated walkways. Pets are welcome on most beaches in Belgium outside summer months, and service stations often have designated dog areas.

Fatigue management: The straight highways can hypnotize. Plan stops every 90 minutes. Abbeville (picturesque hilltop) and Saint-Omer (cathedral and marshes) break the drive. For hidden off-route spots, visit the Château de Rambures (a medieval fortress) near Oisemont.
