3.9 miles of second chances: the bypass built to outrun Kex Gill’s moving hillside

The Kex Gill bypass has opened on the A59, shifting traffic away from one of North Yorkshire’s most failure-prone hillsides and ending years of diversions on a route that would not stay still.

A road can fail without a crash, a flood or a pothole.

At Kex Gill, the problem was the hillside itself. The new Kex Gill bypass is now open to traffic on the A59 in North Yorkshire, taking drivers away from a stretch that had become known for landslips, closures and the sort of long diversion that turns a routine cross-county trip into a small expedition.

In brief:

• The new Kex Gill bypass has opened on the A59 in North Yorkshire.
• It replaces a landslip-hit section of road that had closed repeatedly.
• North Yorkshire Council said the route will bring major benefits for communities in the county.

Kex Gill bypass opens to move the A59 off unstable ground

This is the kind of scheme that makes sense the moment you look at it from above. Instead of trying to keep patching and propping up a road on unstable ground, the answer was to move the road. That sounds obvious. It is not cheap, quick or simple.

Landslip damage is awkward because it attacks the thing beneath the thing drivers can see. Resurfacing fixes the top layer. Drainage can help if water is part of the trigger. Local repairs can buy time. But where the slope itself keeps shifting, maintenance starts to look like an argument with geology. Eventually, the sensible move is to stop insisting the carriageway stay where the hill clearly does not want it.

The A59 is an important east–west route across North Yorkshire, linking communities and carrying everything from daily commuting traffic to freight and visitors heading across the county. When Kex Gill shut, the disruption spread far beyond the closure signs. Diversions on roads like this do not just add minutes. They redirect traffic onto places that were never designed to carry it, affect bus services, stretch journey times for emergency trips and leave nearby businesses wondering how many customers will simply give up and go elsewhere.

That is why bypasses of failed sections matter differently from bypasses of settlements. This one is less about taking traffic away from people’s front doors than about keeping a strategic local route open at all. Reliability is the prize. Drivers tend to notice roads only when they break. Engineers, less romantically, spend years trying to stop that happening.

There is also a lesson here about the limits of reactive highways work. A patching gang can fix a defect. A surfacing scheme can renew a worn carriageway. A slope that keeps moving is another class of problem entirely. It sits closer to civil engineering than routine maintenance, and it usually takes more design, more land and more patience than the public sees. For readers who have followed other long-running closures on major routes, the pattern will feel familiar: once the road underneath is compromised, everything around it gets harder too, from traffic management to programme risk. We saw a different version of that on the M1 closure between J26 and J27, where one blocked route quickly turns into a much larger operation.

At Kex Gill, the public-facing moment is the ribbon-cutting equivalent: traffic moving again. The real story sits in the decision to abandon a troublesome line and build a new one. That is a bigger admission than it sounds. Highways authorities do not lightly replace live road alignments, especially on established routes. Doing so means the old fix-repair-reopen cycle has run out of road.

Malcolm Taylor, who oversees highways at North Yorkshire Council, said the route would “bring major benefits for communities in the county”. The wording is measured. The effect is likely to be more visceral for people who use the A59 regularly. A road that repeatedly closes starts to train its users not to trust it. Opening a bypass is partly an engineering job and partly a confidence job.

For the sector, the scheme lands at a time when resilience has become a plainer word for a more expensive reality. Wetter winters, sharper rainfall events and aging assets all make road authorities more conscious of weak points. Some failures are dramatic. Others are slow and repetitive, which can be worse politically because they look, from a driver’s seat, like the same problem happening over and over again. In truth, they often are.

The bypass now gives the A59 a route less exposed to the slope conditions that kept undermining the old road. For residents and businesses, that should mean fewer disruptive closures and a more dependable connection through this part of North Yorkshire. For drivers, it means one less road where a routine journey could be rewritten by a moving hillside.
