A4174 Improvements: A Better Route Deserves Better Alignment
South Gloucestershire Council has finished major A4174 upgrades. Here's what smoother roads and resurfacing mean for wheel alignment and suspension in Filton.
Good news for anyone driving the Avon Ring Road: a number of sustainable travel improvements along the A4174 ring road have been substantially completed, with over 4km of improved cycle lanes and footpaths between Wick Wick roundabout and Coldharbour Lane. The council's announcement, published 12 November 2025, confirms the scheme has reached a major milestone for local travel.
According to South Gloucestershire Council, the work includes new paths, widening of existing paths, resurfacing and new pedestrian crossings, along with an additional left-hand lane for vehicles on Coldharbour Lane and new speed limits on parts of the ring road. Some elements are still being finished off: final stages of resurfacing the ring road are still underway along with traffic light improvements at Quakers Road junction, due to be completed by mid-December.
What smoother tarmac means for your Porsche
Fresh resurfacing is genuinely good news for any car's suspension and steering components. Fewer potholes and a more even surface mean less repetitive jolting to bushes, dampers and tie rods. But it's worth remembering that the months of roadworks, temporary surfaces, and diversions that led up to this point may have already left their mark on vehicles regularly using the A4174 corridor between Wick Wick and Coldharbour Lane.
Uneven road edges, temporary lane narrowing, and resurfacing joints are common culprits behind knocked-out wheel alignment, even when there's been no obvious impact or pothole strike. A Porsche's precise steering feel and even tyre wear depend on all four wheels sitting exactly where the factory intended — something that's easy to lose without ever noticing a dramatic clunk.
A practical checklist for local drivers
- Watch for uneven tyre wear on the inner or outer edges, a common sign of alignment drift.
- Notice if the car pulls gently to one side on a flat, straight stretch of the ring road.
- Listen for new knocks or clunks over the remaining rougher sections near Quakers Road, still being finished.
- Get suspension components checked if you've regularly driven through the roadworks over recent months.
This isn't about assuming damage — it's simply sensible housekeeping after a long period of altered road conditions. If you've noticed anything off in the steering or handling, a proper geometry check is a quick way to confirm whether your Porsche is running true.
