A421 resurfacing and junction improvement near M1 junction 13
We’ve been carrying out work to widen the entry and exit slip roads on the A421 junction with Salford Road. We are now also improving the road surface on the A421 near junction 13 of the M1 at Milton Keynes.
We’re carrying out work on the A421 junction with Salford Road. Work will include widening of the entry and exit slip roads, a speed limit reduction and improvements to signage and road markings.
The entry and exit slip roads to and from Salford Road to the A421, plus Salford Road itself between the slip roads, will be closed.
Traffic using the A421 roundabout south of the M1 will not be affected.
Once work is complete, drivers will benefit from a safer and better-defined road surface.
