A4146 is a major junction from Springhill Avenue to Stephens Road.
The A4146 is an A-class road in England running from (near) M1 junction 14 at Milton Keynes, around Linslade and Leighton Buzzard to join the new A505 dual carriageway to Dunstable. In Milton Keynes, the road briefly follows the H6 Childs Way from Junction 14 of the M1 Motorway before turning south onto the V11 Tongwell Street, west again onto the H10 Bletcham Way and once more to the south where it joins with the A5. It then separates again at the Kelly's Kitchen roundabout to bypass the southern flank of Bletchley. At the end of this single-carriageway bypass, from a point just south of the Water Eaton estate, a new alignment has been built for the road to continue west on a short stretch of dual carriageway bypassing Linslade and Stoke Hammond and to hug the West Coast Main Line for most of the way south towards Leighton Buzzard. The route is planned to tie in with a proposed A418 Wing bypass.
