The inner Ring Road is the worst spot for accidents, particularly to the south of the city centre. Three junctions in succession have a poor safety record: those with Trumpington Road, Hills Road/Regent Street, and Mill Road/Parkside. Improvements have been announced for the Hills Road junction, but local cyclists are sceptical that they’ll actually make a difference.
Mill Road itself is avoided by many cyclists. Though there’s a 20mph limit, it still has a high collision count. You can often piece together a backstreet route as an alternative, but unfortunately it’s almost a mile north to the next bridge over the railway, at Coldham’s Lane. Take care on the other arterial routes, too: Milton Road’s shared-use path should be safe, but exasperatingly gives out at crucial moments, requiring you to mix with the traffic.
