The M11 link road protest was a campaign against the construction of the M11 link road in east London in the early to mid-1990s. "A12 Hackney to M11 link road", as it was officially called, was part of a significant local road scheme to connect traffic from the East Cross Route (A12) in Hackney Wick to the M11 via Leyton, Leytonstone, Wanstead and the Redbridge Roundabout, avoiding urban streets.
The road had been proposed since the 1960s, as part of the London Ringways, and was an important link between central London and the Docklands to East Anglia. However, road protests elsewhere had become increasingly visible, and urban road building had fallen out of favour with the public. A local Member of Parliament Harry Cohen, representing Leyton, had been a vocal opponent of this scheme.
The protests reached a new level of visibility during 1993 as part of a grassroots campaign where protesters came from outside the area to support local opposition to the road. The initial focus was on the removal of a tree on George Green, east of Wanstead, that attracted the attention of local, then national media. The activity peaked in 1994 with several high-profile protesters setting up micronations on property scheduled for demolition, most notably on Claremont Road in Leyton. The final stage of the protest was a single building on Fillebrook Road in Leytonstone, which, due to a security blunder, became occupied by squatters.
The road was eventually built as planned, and opened to traffic in 1999, but the increased costs involved in management and policing of protesters raised the profile of such campaigns in the United Kingdom, and contributed to several road schemes being cancelled or reviewed later on in the decade. Those involved in the protest moved on to oppose other schemes in the country. By 2014, the road had become the ninth most congested in the entire country.
