French A7 closures around Lyon

Pierre-Benite works, A46 ring alternative and 2026 Bison Fute black days.

The A7 Autoroute du Soleil between Lyon and Vienne is the busiest interurban corridor in France and one of the top-three congestion blackspots in Europe. The Lyon section (PK 0 to PK 30) carries roughly 130,000 vehicles per day in summer, with recurring works at Pierre-Benite, the Fourviere tunnel and the A6/A7 junction. This guide explains which closures are permanent, which are seasonal works, what works in 2026, and the realistic alternatives if you are transiting north to south or south to north.

Permanent post-2022 changes north of Lyon

The biggest change long-distance drivers still miss is the declassification of the A6/A7 between Limonest (north Lyon) and Pierre-Benite (south Lyon). Since November 2022 this 20 km section is no longer an autoroute. It became M6 and M7, a city boulevard managed by Lyon Metropole rather than APRR. The speed limit dropped from 90 to 70 then 50 km/h, lorries over 7.5 tonnes in transit are banned (locally licensed deliveries only) and cyclists are now permitted on certain on-ramps. Sat-navs that still call this the A6 or A7 send you straight into the city. For through-traffic, the official long-distance route is now the A46 east-side ring or the A466 plus N346 west-side connector.

Active and planned 2026 works

APRR (the A7 concessionaire south of Pierre-Benite) and Vinci Autoroutes (further south past Valence) publish a rolling 14-day works calendar at aprr.fr and vinci-autoroutes.com. For 2026 the recurring items are:

Pierre-Benite viaduct (PK 5 to PK 8): structural strengthening on the Rhone river crossing, single-lane reductions overnight (21:00 to 06:00) most weekdays March to October. Resurfacing weekend of 27 to 29 June 2026 with one carriageway closed.
Givors interchange (PK 22): northbound off-ramp resurfacing, evening closures only, June to August.
Vienne-Sud (PK 30 to PK 35): noise-wall construction, no lane closures planned but speed limit 90 km/h instead of 110.
Vienne tunnel access: occasional weekend closures for ventilation works, one weekend per month August to November.

Exits that are permanently closed or repurposed

Several historical exits no longer exist as full junctions:

Exit 1 Perrache: closed since the A7 became M7. Approach via Lyon city streets only.
Exit 2 Confluence: kept open as a city boulevard exit; no longer a motorway junction.
Exit 3 La Mulatiere: northbound only.

Detour routes if the A7 is fully closed

On peak summer weekends (Saturday departures in late July and early August) or after a major accident, the A7 can be completely shut south of Lyon. The recognised alternatives:

A46 east + A47 then back to A7 at Givors: adds ~25 minutes in normal conditions, much less if A7 itself is jammed. Used by all long-distance lorries since the 2022 reclassification.
A47 via Saint-Etienne to Firminy then N88 / A75 to Clermont and back south: a 200 km detour over the Massif Central, but bypasses the entire Rhone corridor. Used only when the A7 is shut for multiple hours plus the A46 is also saturated.
National roads N7 and N86: parallel to the Rhone on both sides, free but slow (50 to 70 km/h limit, traffic lights through every village). Useful for short hops between Lyon and Vienne but not for through-traffic.

Bison Fute red and black days 2026 around Lyon

The French national traffic information service publishes a forecast calendar for the year. Around Lyon and the A7, expect these red and black days:

Saturday 26 July 2026: black in the direction of departures (north to south), classic chassé-croisé weekend.
Saturday 1 August 2026: black both directions.
Saturday 8 August 2026: red in the direction of departures.
Saturday 22 August 2026: black in the direction of returns (south to north).
Saturday 29 August 2026: red both directions.

On a black day expect 6 to 9 hours from Paris to Marseille (versus 7 hours nominal) and delays of 90 to 180 minutes around Lyon alone. Departure before 04:00 or after 22:00 is the only reliable way to avoid the worst of it.
