Did you know how much traffic uses the bridge, and what proportion are cyclists? Hampshire County Council ran traffic surveys in 2005 and again in 2011 to find out. The raw results are pretty complicated, but Cycle Hayling has done some hard work so you don’t have to.
Here are the highlights (remember this is now 4 years out of date) :
- The bridge averaged 26-27,000 vehicle movements every weekday during summer 2011. Nearly all would go straight on through Stoke, and it’s WAY, WAY OVER the DfT recommended load for a road of this type.
- And yes, over 400 were bikes! Including 3 or 4 a day between midnight and 6am!
- Cycling averaged 1.8% of all traffic movements during the summer month weekends, and 1.4% on weekdays.
- It’s almost certain that cycling went well over 2% during better weather, as the figures average over a month.
- Cycling grew by 18% between 2005 and 2011, whereas other vehicles fell by 2%.
- I believe the cycle stats are dramatically on the low side, due to the placement of the traffic counters :
- According to the ‘Site Map’ tab, I would never show on these stats, because at the Hayling end of the bridge, I’d be on the pavement, missing the road counters (118/120), and at the Langstone end I’d be back on the road, missing the pavement counters as well (117/119). And I’d guess that would apply to many riders.
- Furthermore, one would expect the North and South bound totals per day to broadly cancel out, as they do for cars. But they don’t – they’re as much as 19% different – which supports the ‘missing data’ argument above.
- So either lots of cyclists are doing one way by bike and carrying the bike the other way by car, bus or ferry, or the counters are missing lots of them.

We’re trying to find out if Hampshire have any more recent stats.
We think cycling has increased significantly in popularity in the 4 years since 2011 – what do you think?
