The MC32 is a route in Amersham, consisting of Rectory Hill, Church Street and Whielden Street. Whielden Street is the former A404.
Beginning in Amersham on the hill, on the edge of the centre, at a mini roundabout on the A416 outside Dr Challoner's Grammar School, and heads down Rectory Hill. After passing under the railway the road is in woodland, with a Scout Hut on the right - after which the road becomes NSL, then narrows to only just being wide enough for a centre-line, and begins its steep decline down the hill after some driveways for big houses.
At the bottom of the hill, the limit returns to 30mph, there is a side turn, a Puffin Crossing and a mini roundabout with School Lane all within quick succession. The road's name changes to Church Street and becomes built up. After passing the end of the church the road meets the MC64 in Old Amersham's Market Square.
South of here, the road takes Whielden Street, a former Roman Road, and from 1935 until the bypass opened, the A404. After passing the Hospital, it passes under the bypass, before meeting the A404 at a limited access at-grade junction.
