KILLARDRY BANK RECORD · 8 SEPTEMBER 2026

What the Killardry footage actually shows

Both cuts in one frame. Junction ahead. Bridge to the right.

There are three photographic moments. They must not be mixed.

Moment A is the tight crop of the toe — stones and clods on the grey seal, near-vertical face, hedge still on the crest.

Moment B is the May walk-through: 42 seconds from the junction, around the bend, onto the deck. Horse-chestnut candles date it. The memorial is already there.

Moment C is later summer growth on the same bank. It proves the face was never finished. It does not prove the night.

Walk Moment B as a driver.

Zero to eight seconds. The road is a tight left-then-right into the bridge. Sightline through the chestnut is short. The right-hand cut and the blue pipe mouth sit in the peripheral field as you commit to the turn. A vehicle parked on the junction grass shows how little verge remains on the left.

Eight to fifteen seconds. You are on the bend. A patch sits in the wheel path. Dark damp streaks run across the seal. Water is using the carriageway.

Fifteen to twenty-five seconds. You are on the deck. Dirt strip, flowers, low broken stone, then the river. That is the already-documented residual parapet. The memorial is not evidence of cause. It is evidence of where the road ends.

The engineering sequence in one continuous shot is: raw cut and open pipe on the approach → tight bend → unprotected deck.

The pipe interiors belong with that sequence. Twinwall, silted, no headwall, daylight through. The later summer frames belong after it: bare soil still there, coloniser weeds in the mound, established butterbur higher up where the old bank was not cut.

What the footage does not do is put clay under a specific tyre at 22:00 on 24 April. What it does do is show the source term — an uncovered cohesive face and stones at the exact line a front tyre uses on the turn — and the absence of the measures Irish rules required if that face was still open after dark.

TRL tests on clay-contaminated asphalt found that a legal tyre on clay behaves like a tyre on a wet road, not like a tyre on ice, unless the tread is gone. Denis Wood Associates already found that this bend demanded a large speed reduction in the wet at the posted 60 km/h. The footage is the condition of the edge those numbers meet.

“The camera recorded an unfinished edge in the radius of the turn. The standards say that state was not to be left live at night.”
