A509 The road begins at a roundabout with the A418 and the A4146 south of Leighton Buzzard as a wide A-Class Primary Route. The road passes through two roundabouts as a single carriageway, and acts as the Leighton Buzzard Bypass. To enter Leighton Buzzard from the A505, an advisable route is to use the A4012 North from the roundabout at Billington. Southbound on the A4146 from here will take you towards Hemel Hempstead and Whipsnade Zoo. Continue along the A505 along a 50 MPH stretch with speed cameres to reach the A5. The A505 continues in Dunstable. The A5 south allows you to reach Luton and Dunstable. There are speed cameras again on this piece of road. An east turn in Dunstable takes you to Luton on the secondary A class road, A505. The A505 will reach the M1 motorway at Junction 11. Going northbound will take you to Milton Keynes, Northampton, Birmingham and Leeds, whilst Southbound is heading towards London and St Albans. Prior to this is a roundabout with the road number A5065. Taking the A5065 into Luton is a replacement to the A505 which resumes after Luton as a dual carriageway. The route through Luton is as follows: A5065; A6 South East to the Airport; A505 North, or use the M1 (M1 South; Exit at Junction 10 and travel North on the A1081 and rejoin A505) A4146
